Your welcome. Thanks for watching.

@@DavidPozEnergy I literally liked and subscribed your channel at 0:36 because I realised you do this. You are a legend among american youtubers. Much love from down under

True, we are an international audience and the ONLY country to still use pounds is the US.

I was just about to comment exactly that! Thanks!! No need to pause and Google "163 us pounds to kg" 😂👌🏼👍🏼👍🏼

if you have an issue with any of your purchases ... how do you contact them??

@@websterbrauzer8373 phone or email I think

Could you please help me connect with them to buy some batteries right here in this comment section or I could write you my email a phone number or some way to contact them

Your welcome. Thanks for watching.

DavidPoz watching from U.K.

Absolutely! I look forward to testing them.

Nice! When you get them up can you send me a picture? (maybe facebook) I'd love to see them.

DavidPoz will do! It’ll be next month or Jan... waiting for the Sol Ark 12k inverter to come in. It ships in December.

Awesome! I can't wait to see someone with the Sol-Ark 12k installed. That thing looks like perfect on paper. It checks every box on a wish list.

@@DavidPozEnergy Curious if you've found a way to capacity test these yet?

@@DavidPozEnergy So... after seeing a super awesome deal on the SMA Sunny Island($1500/ea) I couldn't turn that down. So, instead of the Sol-Ark, I went with the Sunny Island. I have 3 buildings that I'd like to eventually place panels, so this would make it really easy to AC couple them with Sunny boys back to the island. Thanks again for your work and impressive builds!

Thanks for checking out the video. 18650's are great too. Anything that helps us get more energy independent!

Thank you, means a lot coming from you.

Im a huge fan of both channels. Thanks for making such great videos!

Thanks for using the link. Are you planning a 48v setup?

@@DavidPozEnergy yes. I want to add these to the battery bank I currently have. I have 16 Sol-Ark 12volt PCC's in 4 strings for total 920ah. I have never had to wire up a BMS. Which one do you plan on using for these?

I took a look at your system. The Sol-Ark looks like an amazing machine. It seems like it can do everything. I'm surprised you didn't buy more of the Sol-Ark batteries, I think they are AGM, right? As for my BMS, I think I will try the Chargery 16s BMS.

@@DavidPozEnergy Not that I didn't think about the Sol-Ark batteries but they were $700 each they are partial charge carbon. The hookup ones were a much better deal. Just have to work out the BMS for them. They will be added in parallel to the Sol-Ark ones. The Sol-Ark system is very flexible, they just came out with a 12Kw unit.

Hi proto, Thanks for sharing with us how these would be installed. That's interesting. As for cables, I am planning to make my own. I could not figure out what these posts are called, or where to source the female version of them.

@@DavidPozEnergy I have an idea, you could use some sort of metal cable clamp on them, instead of cable you clamp onto the post. Then use the clamp mounting hole to attach the power cable, using a nut/bolt.

That's great. I saw your other comments. What are you planning for BMS wires? Will you run your own direct to the cells?

DavidPoz I like the wire setup they come with but i have a box of 18awg color variety I bought on eBay or amazon 100 ft each roll that would make cell ID easy enough. How many S Chargery bms were you looking for? Mine is 16s good for 48v setup.

Yes, I felt really bad for my van. I didn't know how much they weighed when I went down there. I had done a back of napkin calc assuming 120 pounds each. LOL. That would have been right on the edge of my payload. I was wrong. Thanks for using the link. I just found out about the affiliate program yesterday, after I already bought the batteries.

six? they are heavy beasties! your mpg is gonna go down ;)

These units are 4.5kWh each now, originally rated at 5.4kWh

@@BenMitro in renewable energy, we dont express battery capacity in Kwh...because wattage goes down as voltage goes down....however you can have a constant amperage draw till your batteries are drained....thats why

@@t00ls742 kind of. Except that amperage goes up as voltage goes down because your load is a constant wattage draw. These modules are originally listed as 5.4-5.65 KWh. There is nothing wrong with describing a battery in KWh capacity.

DavidPoz So is it 100$ per modules when you brought it’s. Am I reading it correctly? On the website is say 450$.

Sorry to disappoint Mark, but I had to sell the Volt pack to help pay for these.

Fully agree, I payed £250 for 8x60AH used Sinopoly cells a couple of months ago

just looked and the guy has increased the price to £350 plus shipping :o

Are leaf batter good for backup power wall? I heard they degrade fast

@@jollygreen4662 I hope not, but I just got mine a few weeks ago. I wish I would have waited to see this deal. If you oversize it, you can use like 15%-20% of you capacity so it will last longer. I just cooked, dried clothes and turned the water heater on with 81% battery left for the rest of the night. Definitely oversize as much as possible.

I agree with over-sizing. The batteries will last longer. It's just the cost. I'd love 100kwh, but just the cost gets too much. We do what we can.

@@DavidPozEnergy buy 1 per month for the next 12 months, lol. But I completely understand that, I'm on that very same road.

Thank you for mentioning me. I'm sure it will all work out. I bought the batteries on my own and didn't even know there was an affiliate program. I was going to make videos about them anyways. The owner (Tom) suggested I get into the affiliate program.

@@DavidPozEnergy You are welcome, They told me shipping is 350 for as many as I buy, so 20 cost me same as one. Plus I got 10% off. How much was your gas plus time, I live in Portland Oregon and I am pretty sure my Prius is not up for the task.

20 is going to be one heck of a big system. I spent $130 on gas and tolls. But who knows how much damage I did to my shocks. I might have to replace them soon. LOL

@@DavidPozEnergy Yes, I generally have Les Schwab do a free inspection, because it is a safety issue. They will tell you if something bent or failed. I consume 50 kwh a day, so 2 days worth of power. This includes all electric heatpump HVAC, Heat pump water heater, led lights inside out, security systems, I tested enphase micro inverters for grid tie setup as majority of people, but I think offgrid system are superior. Your inverter setup is good, but as you mentioned you are planning to upgrade to better efficiency inverter, I would recommend trace sw4024 or SW4048 with 93 or 94 percent efficiency. They can be connected together to give you 8kw of 240v setup. You just have to search on craigslist. I only paid 600 each so 1200 for 2 of those.

@@wasifsyed1085 I am hoping to do a similar project to yours with a small garage with an apartment above. It's about 840 square feet total and it will be heated with mini splits. How big is the building that your are using 50kwh to power and heat?

Thanks.

@@DavidPozEnergy More than likely either the; electromagnetic radiation, caustic fumes, or perhaps accidental electrocution has affected David James in calling this a fixed jumper (sorry Dave). As an EE, any device that carries a high current load would use a solid high conductive metal connection between electrical junctions such as these to connect between batteries. This is called a 'Buss Bar' not a 'Fixed Jumper' which would allude to an EE that it is connected via an actual wire but because of the high amperage a solid core flat metal would be used as shown in this device. Where a (solid or stranded core wire) renders it a design flaw and electrical hazard due to the fact the electrical atoms (pos & neg) travel outside of a wire so available surface area is nominal that caused heat and over time failure of the connection itself. One would have to have a very large wire gage to equal the Amp carrying capacity of a solid buss bar versus a fixed (wire) jumper. However, there are exceptions and those vary from manufacture to manufacture in naming these devices just to make it more confusing and the fact to save on production costs and increase profits use of wire for a buss bar is readily used in the industry - just a way of saving money for the company and not the end user. It is common to see Buss Bar's being replaced with 'Jumper Wire' both stranded and solid core both in high end and low end consumer grade equipment. In industrial equipment you will see these 'Solid Metal Buss Bars'. Unfortunately, in this day and age increasing profits is the norm and what was once looked upon as ineffective or dangerous has now become acceptable design considerations with the risk they may impose by mitigating this risk with added fuses and other fail safe measures. We see this all the time with new buzz words (in reality old words) to make it sound like the newest high tech solution and thanks to the marketing department of the company, justify its design inefficiency to the user. This becomes apparent when reading the products data sheet and/or lack of proper information in the data sheet. Best advice I can give you is check your connections are they the best way to connect this device? Are they solid mechanically? Wear and tear possibility? Corrosion? Safe? Is this the best way to make this type of connection? Remember the path to least resistance for failure is you connections. Be safe, do it the right way and with quality equipment... Happy Energizing! Nicholas

He did say he's in Bahston

Last I checked I was averaging 14kwh per day. I hope this tides me over. LOL

They had a truck load worth, crazy they sold out already. But they are a great deal. Sorry you missed out. On their website they said they are going to get another truckload in 2 weeks.

They "were" GONE!!

LOL

@@DavidPozEnergy I will die to get few of those batteries for my inverter. Still iam DROOLING obout that battery

Thanks. What was your cost in kwh?

DavidPoz $417, with box and BMS, to my door. $1,001 for a 24v 100Ah. And I’m in Pa so I will he making a trip up there at some point.

Yes I should have rented something. As for stock, I think these will sell out fast. I didn't see a lot when I was there.

Yes, same place. I said Philly because it's just easier for the video.

@@DavidPozEnergy Did you have to make special arrangements to pick them up in Bensalem? Their website says no local pickup :-( That's a deal killer for me because I'm just a few hours away in central PA. No way I'm going to pay $300 shipping when I'm that close.

I made a guess, 50/50 chance. Go figure I guessed wrong. LOL

Victory First He for sure didn't do them any favors , do the minivans make audible noise like cars ???

Aaron What general part of the country are you located, Florida doesn't want you to have it , and California almost mandates it, here in the Midwest seems like they don't care one way or the other.

@Michael PacNW I have friends making money putting more into the grid than they need. Not every situation is the same. Most I know break even but will be in the green after paying off their panels

I'd love to hear more about the Kilovault. Are you on Facebook?

@@DavidPozEnergy I actually did fully charge the car off my solar system. It just shutdown several days later. The charger for my car says theirs a fault in the cord I used to initially charge the solar batteries. Next time I charge them I'll use my new cord plugged directly into the wall socket. What do u want me to tell u about the Kilovault batteries. They say they have their own BMS sensors and not to use a separate temperature sensor. No, I'm not on FB. They stop me at the door when they want u to sign in just to look at their site.

LOL, no, not the block. I sold the Chevy Volt battery to buy these, and 4 of these modules are going to a buddy. The 8 that I'm keeping should be around 35 kwh of capacity, which should about double what I had with the Volt battery.

Lysol ! Look into Alibaba.com Hunan Auk Energy Co. Bruce Wong. Same cost for new in your situation. I opened an account and you don’t have to be a company to purchase there. I purchased 32 lifepo4 200ah at $110 each $800 shipping to Philippines + customs + $100 ups contractor bogus “customs storage fee” which ups refunded and fined the contractor. Yay! Anyway they accept PayPal in most cases. Dave should start buying and selling this way. 150ah batts are the cheapest because they are most popular.

I think the shipping is a fixed cost of $350 if you buy 1 or more. Good luck grabbing them next time they get a shipment.

I'm planning to use these batteries to power my whole house. I'm going to pair them with solar, inverter, charge controller, etc. Actually, I've been powering my house off-grid most of this year. Up until now I've been using Chevy Volt batteries. Now I'm going to double or triple my storage capacity with the new batteries. If you want to see my whole system check out this video: kzfaq.info/get/bejne/bZhierGI0auyYZs.html Another resource I suggest is from Alt-E. They are a store that sells solar components, or full systems. They help you design your systems too. But they also have a series of design videos that get down into the details. I really like the videos. www.altestore.com/video/

Hi Salvador, thanks for checking out my channel. I don't recommend these batteries. They turned out to be more of a nuisance. I spent a lot of time trying to get them to work perfect, but constantly required my time to balance. I have taken these cells out of service. If you are trying to build your own, I'd use better cells. Use a 16s BMS, with LiFePO4 cells. That means 16 cells in series, and the exact chemistry of the battery is Lithium Iron Phosphate. This is a great way to make your first battery: batteryhookup.com/products/new-battery-hookup-lifep04-32650-3-2v-5000mah-cells-1 This kit comes with 4 cell modules. You would need 4 kits to have 16 cell modules total. Those arranged in series would give you 16s, for a perfect 48V battery. Then you need to add a 16s BMS. Battery hookup is currently sold out, so try this one: overkillsolar.com/product/bms-100a-16s-lifepo4/ I have a coupon code with Battery Hookup: DAVIDPOZ which gets you 5% off, and helps out the channel through affiliate program.

Battery Hookup is selling them for $450 per module.

I'll sell you one for a grand. Delivered!

Me too! LOL. I ordered a Chargery BMS16s to test. I hope that works. It's not here yet, probably take a few weeks.

@@DavidPozEnergy Please show that built in BMS more. that is doing way more vs just sending out voltage and temp to some unknown external device. Did you see a date code any place on the pack or bms? how old are these things.

Hi Pablo, I posted lots of close-up photos of the computer board on my facebook page. facebook.com/DavidPozEnergy/

I still plan to use a BMS. I simply don't know how to write a computer code for whatever language the built-in BMS might use. I'll be installing an external BMS.

According to a spec sheet I found, if we can get a one of the master BMU units, it should talk native CAN bus to a Victron GX module. (Color control or Venus, or similar) David, can you post any model numbers you can find off the unit? I'll do some googling around. (I already placed an email order for 3 for my Skoolie and hopefully can go pick them up from Besalem next weekend.)

The battery is Model: ABSSM. I have e-mailed BYD, and sent them a message through facebook. No response on either. I was trying to get a spec sheet for the cells. Specifically I wanted to find out voltage for 95%SOC and voltage for 20%SOC. So that I can program my charge controller and inverter.

Keep us in the loop. :)

Try Ship Freight. BYD is from China.

Thanks yep. I ordered my 2 today. Thanks

Yes. I have to kill my van before I can justify buying a pickup. LOL

@@DavidPozEnergy I like your thinking!

I'll be charging them with solar. I have some panels if you check through some of my videos you will see them, but here is an overview of my system (soon to be changed up) kzfaq.info/get/bejne/bZhierGI0auyYZs.html Thanks for watching.

Let's talk on facebook. It won't be my last time getting down there. I'm at facebook.com/DavidPozEnergy/

Yes. I will be mounting an aftermarket BMS on the pack. The eventual goal will be installing shunt-trip breakers so the BMS can open the circuit to the battery. Plenty more videos to come.

You could easily remove the aluminum heat sinks and make the whole thing 6 3/8 inches tall. But I wouldn't break it down beyond that.

I'm going to look at one tomorrow and test if this is possible. I think I may get away with angle grinding between 4-5th cell, riveting a metal loop on both sides and then parallel 1:5, 2:6, 3:7 and 4:8 and then keep the form factor... OR I may have to gut it like they are preparing deer! If one works, you can be darn sure i'm getting a second! Who wants to spend 1500$ and a orion BMS 800$ for Valence batteries?

Where did they come from?

Hi Alan, Here is someone breaking this battery to 12v: kzfaq.info/get/bejne/r9SkfcV8y9LVpnk.html

Hi James, You might be able to help me here? I'm trying to nail down my charge/discharge voltages. For example, with my Chevy Volt pack I used 4.05v/c (volts per cell) for charging, and 3.50v/c for discharging. I thought that made the most sense for capacity vs. cycle life. But these are 3.2v nominal. The literature I find says 0%-100% is 2.5v/c to 3.65v/c. Do you have any suggestions on what set voltages would be good for perhaps a 20%SOC and 95%SOC?

@@DavidPozEnergy you got all you need to find the answers yourself. Bmv712, the mppt 250/100 from victron, you select the lifepo4 settings on the charger and use the active ballancer for the upperbalance on the cells(3,55v as the charger is set for absorb.) Than start the discharge till the weakest cell reach let's say...3,05.I find this safer. Then check the ah consumed on the bmv and you that nr. write it down in the bmv.712 on the capacity settings. And you're good to go. I would recomand a 48v system 2s6p in your case. Hope it helps.

Hi Marko, Thanks for your question. I agree that it's confusing. I've read through several BYD documents. This is a LIFePO4 battery. It seems BYD is using "Li-ion" as a broader term for the lithium family rather than a specific chemistry.

My favorite meter for measuring SOC (state of charge) is the Victron Smart Shunt. I'm running one on my battery bank. www.victronenergy.com/battery-monitors/smart-battery-shunt If you are on Facebook, then I suggest joining the group DIY POWERWALLS I'm on there, and it's filled with helpful people. And you can attach photo's.

It looks like the heat sinks are attached with 4 screws, so it should not be hard to remove. But it probably only saves you 1% of the weight. The cells are really big and heavy. If you are building something for a mobile application, like a van build, then save the weight and go with something else.

I just posted an update video on them. kzfaq.info/get/bejne/iq1ka8ZmnJeoZn0.html

Depends on chemistry. The ones in this video are LiFePO4 and 16s makes a good 48v. But in some of my other videos I use Li-NMC and they want 14s for 48v. I clear this up in a video: kzfaq.info/get/bejne/ech4dKWjuda3e4k.html

Hi Roy, I don't do service anymore. But let me check in with a friend who does and see if he is willing to let me give out his number. Please send me a private message on Facebook. facebook.com/DavidPozEnergy/

If you can get in touch with them, they might have a few that they did testing on or something. Alternative, they sell those cool Nissan Leaf batteries (full out of the car). Those weren't available when I bought these, but would be what I'd try next. You can use my coupon code "davidpoz" for 10% off anything.

@@DavidPozEnergy Thanks David. I'll give them a call tomorrow. I'd probably avoid the Leaf batteries. They are lithium-manganese-oxide which have a very short cycle life as far as lithium batteries go. They are only rated for 400-600 cycles when new, and those are pretty well used up. They'd probably go downhill quickly. I suspect these LiFePO4 batteries have 1000 - 2000 cycles left in them before they become unusable. Seems like a better deal to me. EDIT: Just noticed a few comments about bad modules and some very weak cells. Maybe I'll steer clear of all of these used BYD packs and just go with building my own from new Liitokala cells.

Wikipedia says 2,000 cycles. This generally is until you hit 80% capacity of the original factory specs. These are used batteries, taken out of service and are about there. I'd be happy with another 2,000 cycles down to 60%. But there are lots of different versions out there. I've seen some manufacturers claim 8,000 cycles. I can't find original documentation for these batteries, so I don't know where exactly they fall on the spectrum.
