Great Jorb! Not for me though, I've become a 98Lb. weakling in my advancing age. But, it's nice to see those 32700 cells being put to use (that's what's inside of my AimsCorp '50AH' (47.5AH?) 600 W Bluetooth enabled LFP battery that I paid big money for last month! But, I complained about how over-sized & over-weight it is for two weeks... until I got very satisfied that I will be able to cycle it for like 14 years before it gets too tired and only has 40AH. Will Prowse motivated me to build a portable power source when he started the Milk Crate builds!!!

Nice work! You can calibrate the voltage which is read by the balance leads... not sure if you can do it on the app but you can do it with a windows computer and a USB to serial adapter... the software is a free download. It may be worth checking to make sure the voltage of all the cells are what the BMS say they are. I've had to calibrate 2 out of 3 of my BMS's.

Hey look!! It’s @DavidPoz !!! This guy & you, David, are the nicest and easiest to watch people I follow on CensorTube!! It’s so awesome to see you come over to support a “competitor” (even tho I don’t often see him looking at comments like u do.. 😬 no offense Lithium man! Love ya! 😂) - David, i messaged you in the past about working with a FULL Smart FORTWO battery pack in factory condition, but you didn’t see it. I’m in NJ literally 2 minutes right off exit 16 on the NJ Turnpike (on the way to Battery Hookup!) - would you be interested in giving me some help or doing a collaborative video with me where you’re the brains of the job while I do all the physical work and video it all??? PLEASE??? I have professional videography & editing capabilities, so ALL YOU’d BE DOING is coaching me here and there while taking full credit for the video... It would sort of be a motivational video showing people that (with a little help from a friend) ANYONE can salvage batteries and create potentially lifesaving powerwalls or portable “generators”... For a little background on the battery - I obtained this battery directly from a friend who’s a technician at a local Mercedes Benz dealership... The battery was producing an “error code” on a brand new Smart FORTWO that corporate decided to just send a replacement battery to the dealership over (since they DO NOT allow technicians to even open these battery units, let alone work on them!) - The dealership received the battery in a beautiful $800 wooden elevated shipping crate and were told to “SHIP THE FAULTY BATTERY BACK TO THEM” .... “AT THE DEALERSHIP’s COST......!!” - As you know, all dealerships are privately owned, and the owner said “F U” and never sent it back.... The technician knew I was interested in building batteries, got it “OK’d” by his boss, and dropped the crate off in my driveway!! All 700 POUNDS OF IT!! Since I’ve been following you for a long while, I’m well aware that you managed to make a DAMAGED FORTWO useful and you know your way around it in ways that most other people in the entire world DO NOT. You’re the ONLY PERSON I’d be able to ask and my skill level simply isn’t at the point where I could even begin to dive into this massive beast... So, again, PLEASE consider my offer. A free, inspiring, detailed (and basically FULLY EDITED) video for your channel, plus some cash or goods for your time & expertise in exchange for simply making yourself available around YOUR schedule to give me some telephonic walk-thru assistance until completion.... Cmonnnnn buddyyyyyy!! My email is at protonmail - d0t - C0m- and you just add my KZfaq handle to the front “flojotube @“ I’ll also leave a copy of this message on your most recent video and I’ll try to find your email as well. I think it will make for a potentially GREAT video (as I’ve seen other channels doing “DIY REPAIRS” on this battery with 1M or so VIEWS) that I’ll be sure to produce w/ HIGH QUALITY video/audio and editing to meet your standards while you help me reach the level of security during a blackout that I’m wishing to get to so my kids and grandma have some peace of mind... ✌️

Nice job, anyway I would mount a fan and take off the blue plastic wrap, so that air can circulate among cells. Such big arrays of lithium cells need cooling, and with the plastic wrap the core of the array can get hot, while the periferical cells, where the thermal sensor is, may not get hot as the center. Thus the center cells can fail sooner than the external cells.

I would have taken the nickel strip used, folded it in half to crease it, spot weld one half to the Pack with the positives, and spot welded the pack with the negatives, then would have folded the pack into one another, and also put the barley paper in between. But that's just how I would, doesn't mean it was done wrong here. Great Video!

I don't have the patience to work with the smaller cells like that, but if you need a higher voltage output, in a small(ish) package size, this is the way to go. At some point I'll have to build a 24v, ~50AH battery to run the trolling motor in my boat. What cells would you recommend for something like that?

Good build video and thanks! I might however suggest checking all cells and top balancing before spot welding. I recently received a 130 of these cells from Battery Hookup and found three cells had self-discharged to below 1V. After top-balancing a group of 40 cells including the three self-discharged cells, after 5 days those three cells as dropped between .5 and .8 volt, and when fully charged only delivered about 3800mah. After building a 20s X2 pack, I found another 4 cells that delivered between 4800 to 5000mah of capacity. The date on these cells is '09-20', so possibly two years old, so I may have got a bad or old lot. Batery Hookup has not responded to my messages. As Such, I might suggest buying a few extra cells if building a pack, I would be interested in the date of the cells you got are, and if anyone else has had a similar experience with these cells?

Yeah. You can't do that here because the packs have an even number of series connections making both +/- on the same side of the battery. You could do 6-5-5 instead of the 6-6-4 I did, but then you can't fit it in the toolbox because of the lip that I had to slid the 4-wide pack under. You'd need a larger toolbox or different kind of container. Thanks for the idea though :)

That said, the 2170s that Big Battery sell (or high-end 18650s) could fit over 9 kwh in that same space. Still, the LFPs are safer in general and should last longer.

@@DavidHalko I haven't used any specifically for LTO, but you could use something like the below link. That said, I wouldn't get a high amp bms for LTO. Better to use a relay attached to the bms. It will waste some power, but not usually a big deal. I also wouldn't trust any bms alone. Every 5s is basically a 12v setup. 10s=24v, 15s=36v, and 20s=48v. If you use for a solar/wind system, make sure that they either support LTO or that you can adjust max voltage. It is much safer and unlikely to have issues as long as you stay close to the max voltage. www.aliexpress.com/item/1005001360189653.html?spm=a2g0o.productlist.0.0.4dfe532cBjUmNX&algo_pvid=1369bc49-6fb9-4657-941c-3133ccd3894c&algo_exp_id=1369bc49-6fb9-4657-941c-3133ccd3894c-8&pdp_ext_f=%7B%22sku_id%22%3A%2212000020266819002%22%7D

Thanks for the video. Considering building a 48v off grid battery bank using the same cells as these. Since these are lifepo4 do you think there's any need for cell level fuses in a big battery setup?

A sodium battery could be used in front of any condo parking spot charged all night and day slowly, then a higher discharge charger cold be used for a good five to eight hours of good vehicle charging. All this could be done easily for a condo renter or owner to have a power company to install a power connector from the living unit being charged for a little power used at low peak times.

open barrel lugs are by far the best way to go. all these other connectors, like solder ring inside heat shrink type junction connectors, squeeze over tap connectors, etc. they are all crap. open barrel is the way to go. as a bonus, you can also solder these without melting off your shielding. go with some harbor freight marine grade heat shrink, with the glue in the center, over your open barrel lug, and you will now have a water tight connection that Will rival some of the best factory connections. 😏💯💯💯

That's really cool! I ordered a bunch of those k2 energy cells they have right now, and I'm planting on building a solar generator and a 12v RV battery.

Wondering why didn't you use the XT90 ?? I mean the littles 60's would do but with that kind of power I would have go for the safe than sorry thing... great video.. I really like it ! !

just for ref .... pelican cases make better battery boxes. They're non-conductive, usually "weather proof", don't rust, are easy to put ports/holes in without sharp jaggies, etc...

Battery is a very small part. Peak tourque and current of Motor matters. If 48v I'd assume 30A drawn which means at rated RPM and load u can do max 2 hrs (84AH battery)

so with that uneven voltage in the end (unballanced cells) ... if you wait an hour or two ... let the cells ballance ... you can still get quite a bit of power out of it. right?

You forgot to mention that you have to make sure the cells are charged to a similar level when you connect them in parallel with the nickel strips

I did not do any pre-charging before assembling Doing so would have helped the balancing issue during capacity testing though...

@@LithiumSolar yeah I’m pretty sure you were safe, but that’s assuming someone bought new genuine cells. Il they usually get with pretty close voltage. My comment was more for people that diy packs with their own tested cells. Cheers!
