It’s definitely a great value battery! Glad you liked the grading scale! Should serve you well on your camper! Have fun be safe! 👍

110V inverter they set it at 110 to so they can ship to countries that use 100V 60hz or 120V 60hz.

Super humid here all the time! Usually get 80-100” of rain a year. Had 130” in 2019! .

@@THEOFFGRIDMOUNTAINHOMESTEAD we are in North central WA state. We are on the dry side. The Pacific Ocean dumps it all on Seattle 9 months per year. We get about 30-35 inches per year. Humidity levels are very low. Plus we are 3K feet up in the mountains surrounded by national forest

Heres a video to the copper bus bars from my other comment to you. Didn’t want to take away from XZNY video kzfaq.info/get/bejne/j8qGg7Coks-YiHk.htmlsi=CsP3t4mq41-7G9ca

@@THEOFFGRIDMOUNTAINHOMESTEAD yep I saw these. I subscribe to Dave as well. That’s how I found you. What are those red switches on the wall? Thanks for you info! 😂I wish you were my neighbor. With what I am learning from you I will pass this on to our off grid group!

Each series set of 2 batteries has its own OCPD Fuse and disconnect. The red switches are the 350A blue sea disconnects for each set. Isolating portions or a single set in case there’s ever an issue. He didn’t want breakers wanted fuses. Glad to hear that I’m helping! That’s what I enjoy most!

Correct 2 batteries in series for 48V 6V@400Ah X 8 batteries is 48V@400Ah. 48x400Ah=19.2kWh with 50%DOD for lead is only 9.6kWh usable daily for longer service. The lithium in the video 25.6V@100Ah (2.56kWh) X 2 in series is 51.2V@100Ah (5.12kWh) 4 of these 2S x 2P is 10.24kWh more than your current “theoretical safe 50%” daily discharge. 8 would equal more than your lead acid nameplate capacity but with 100% available capacity and part state of charge capability. You’ll have to add in a bus bar setup and I recommend overcurrent protection device for each series set of batteries. Connect battery to OCPD, then to positive bus. Positive bus bar has its own OCPD between it and the inverter rated for your inverter and wire. Negative goes to bus from each battery then bus bar to negative inverter. All chargers would tie to bus bars with OCPD as well. This is the quick course lol.

@@THEOFFGRIDMOUNTAINHOMESTEAD you have no idea how much I appreciate this. A negative bud bar would just be a copper bar with standoffs. What would a positive bus bar be? Seems it would have to be protected physically somehow unless I am missing something? Any particular brands/suppliers you recommend? Using only 4 of these at $1200 would be cheaper than 1 of the SOK brand batteries I caught up on a few of your videos today. Also shared with a friend…

Many brands of bus bars that are rated for 48V and higher! Victron/Blue sea make them with covers. Or you can use the 1/4” solid copper bar style and fabricated a lexan or plexiglass cover or put them in and electrical enclosure or midnight solar makes DC combiner boxes. Many safe options depending on your budget and taste!

@@THEOFFGRIDMOUNTAINHOMESTEAD already looking ! Thank you! You have steered me in the right direction my friend

I have plenty of 4x12 setups. This requires a balancer $70. More wire and terminals for a 4 unit series connection $30. Only time I’ve had a 4x12 pack stay close without a balancer over time is sequential serial number units. You are correct a 4x12 has lower cost from a replacement aspect if battery fails in the string. But that’s only 1.28kWh. So half price of a 2.56 kWh (24V) battery! Or one could keep a spare BMS for $50 and be back up quickly. During warranty period this isn’t a concern.

​@@THEOFFGRIDMOUNTAINHOMESTEAD Good point, hadn't figured in the warranty, although with a cut-rate a company, I wouldn't put much stock in it.

Thanks! Will do!

It’s an awesome battery! Planning to use it some for the house system with dc to dc charger so I can rob energy from it on rainy days from the cart!

@@THEOFFGRIDMOUNTAINHOMESTEAD I't will be great to watch ! TAKE CARE..

I calibrate at the top of charge! They are very close even done this way, maybe only 2-3% off. I never go much below 50% SOC anyway so it’s ok with me! It’s recommended for max accuracy to deplete the battery bank and let it count the energy coming in. Hope this helps!

On this 12V system I use 4/0 windy nation cables to victron 600A bus bars. I have the 3000W inverter fuse de-rated to 300A. Never go much above 70% load. I always oversize and underutilize! Battery cables are 1/0 with each battery having its own 100A OCPD.

This mosasaur is definitely lots of energy for your golf cart or solar power system. I’m planning to set up a dc to dc charging system to rob power from the cart back to the house on rainy days!

That’s what FedEx is famous for!

It’s better than most server rack batteries I’ve used! The contactor based BMS instead of mosfets is very nice!

@THEOFFGRIDMOUNTAINHOMESTEAD yes I like that as well. I like contactors because I am use dealing with them in my line of work.

Just another example of hillspeak lol

Minus $400 mosasaur coupon minus 13% THEOFFGRID coupon = $1304.99

Nice, thank you. ​@@THEOFFGRIDMOUNTAINHOMESTEAD

You’re most welcome! Take care be safe!

Definitely! Passes the drop test 😂!

got mine! $647 off!

Awesome! Glad you got yourself a deal!

​@@brandonryan3939 how?

I have yet to test the ultra mini, but I check battery prices often, I saw the mini for $189 a few weeks ago! Sorry I don’t have the exact price point for you! I wanted to try something different on this test , I couldn’t risk damaging the battery by opening it due to wanting a long term daily cycling test for these models! With a mini, most often the case has to be destroyed to get to the sensors! The ones I do cut open, I always use an ice pack first before resorting to anything colder. Most of the proper program BMS drop with a regular ice pack. The ones programmed wrong take the colder stuff to make them trip!

@@THEOFFGRIDMOUNTAINHOMESTEAD Yep - that's why it's good to see it legitimately demonstrated/working. Thanks!

Glad you liked it! Thanks 👍

Thanks for the subscription! Awesome that you are off grid! I’ll give you a condensed answer here, but I’ll make a video for you coming up to explain better! In a series set of 4x12 for 48v over time the voltage between each individual battery can stray away from each other, this can be from variance in cell resistance, and other factors. Eventually they can get so far out of balance capacity is diminished. The balancer keeps each battery at same voltage by taking energy from higher battery and putting to lower voltage battery/batteries in the string. This way each is at same SOC and one battery won’t reach low voltage cutoff or high voltage cutoff before the others! Hope this helps!

@@THEOFFGRIDMOUNTAINHOMESTEAD so for my 48V system, I have 8-6Volt 400 Amp hr Fullriver AGM batteries. Would a balancer be beneficial? What brand should I look at? At some point in the next 3 ish years I will want to replace these batteries with LiFePo’s. I see where the expensive SOK batteries last for 10-20 years. Mine are indoors and never get cold or hot. But these that you are showing are a fraction of the price. How long should they last? Thank you for the responses. Love your channel. I will be viewing some past videos to play catch up.

You can take a voltmeter and check each individual battery. If voltage is off by more than 0.25 you may want a balancer. Since it’s lead, your going to be absorb charging and occasionally equalize charging which is different than lifepo4. You may be ok! The LiTime balancers are good, they make a faint noise, the POWMr work good too make more heat than LiTime. Of course there are more expensive options Victron, Sterling etc. All my series packs stay between .00 to .02V apart using both The cells in LiFePO4 if true Grade A will last decades. Some studies have found 40000 cycles. The BMS is what will go. Most manufacturers estimate 10Yrs on a BMS. Lots of variables. There are quality and affordable units out there that sometimes deliver better performance than expensive units. Probably get double or triple the capacity for same $ with something like the XZNY. Glad you like the channel! I’m glad another off-gridder is here! Awesome!

@@THEOFFGRIDMOUNTAINHOMESTEAD and I am a retired electrician at that. Commercial industrial work for 36 years…I never did a lot with DC but am learning for sure. Your videos are great by the way. You explain things very clearly

Very good price point! Never thought LiFePO4 would be this affordable! LTC is a nice bonus!

You’re most welcome! Thanks brushbum!

You’re most welcome!

You’re welcome, thanks for stopping by!

I’m running several XZNY and they are doing well! Glad to hear you are enjoying your batteries! Appreciate you watching and sharing your experiences!

You have always got some of the best real world tests for batteries. Thanks for sharing the review of the batteries and look forward to seeing them tested.

Appreciate that kind sir! Try to keep it interesting lol. Didn’t want to risk damaging this one I’m running it for a long term test! Being a mini, the case would have probably needed cut to get to sensors anyway.

@@THEOFFGRIDMOUNTAINHOMESTEAD definitely

Snow would be perfect reflecting surface! You’d make BIG power!

Glad to see you back sir! Was thinking about you the other day. Hard to do anything without google accounts nowadays! As for your PV, that depends on what you’re wanting to achieve, if I remember correctly your system is grid tie no battery. So you would have to think in terms of investment. Is it worth the $ for panels to offset usage or get some payback from utilities depending on your metering agreement. OFF GRID, it’s a different matter. If you’re weren’t keeping up with loads and getting batteries charged it definitely would be good to upgrade. Good to see you back in the comments! Reach out with further questions if needed my friend!

@@THEOFFGRIDMOUNTAINHOMESTEAD I am still grid tie only but come tax time next year I'll have my initial install paid off and will be looking to add batteries to the system. The main reason I asked though was because they sized my system for yearly average use so it never seems to be enough to break even in the summer or winter months. Though I'll have to see what happens with the batteries first I may look into either more panels or higher wattage ones. Once I get the batteries done I wanna put in a garage and MAY put solar panels on that roof as well later on. Not for running the garage specifically but for adding power to the entire system. But that's a bridge to cross in another lifetime as of right now. Also my potatoes failed again this year... did 20gal grow bags with windows on the side and they did the same thing they did last year where they came up, looked good for like 3 months and then died... dug them up and got 2 tater tots out of 7 seed potatoes. IDK what Im doing wrong.

I’m late in replying! Sorry! Always glad to see you in the comments!

@@THEOFFGRIDMOUNTAINHOMESTEAD You Bet ! TAKE CARE..

Surprised by the cheap glass, mines been holding since initial sight in. Might have got lucky! Was going to upgrade after this video, but it does what it needs to do!

No it’s from China, like 99% of the others! Even US based companies just assemble batteries with China made cells! Two US companies are supposed to come online this year for EV cells, no info on consumer/solar market though!

I have heard similar things about Ecoworthy! JJN is legit and makes real power!

The charger can go up to 85VDC! This unit is cable of 400W sound like your wall charger is 900-1000W Solar energy is free though after you buy the hardware!

I was surprised to see how well it was made! Very nice cell pack in this one!

Awesome! They are worth it! I was impressed with the power! In further testing even early AM with sun way off to the side and low the panel will pop 100-110W. Actually doing better percentage wise than my QCells.

Good to hear you use JJN and are happy! I’m thoroughly impressed with JJN myself! Glad you enjoyed the video!

Thanks!

JJN puts sales on quite often. Price always seems to be lower on Amazon vs their website too!

Honestly I have no idea what would cause this. All the videos have the same settings on my end. That’s very odd. Thanks for going through the extra effort, I’ll send a message to YT creator support and see if they have any suggestions.

@@THEOFFGRIDMOUNTAINHOMESTEAD Interesting... I went back to grab a screenshot of the error... and now it plays. But it happens somewhat regularly... next time it happens, I'll grab a screenshot... although I think it's just a generic message... but maybe it will be helpful. One does whatever is necessary (within reason) to gain useful information.

Bifacial have been out for a while, just now getting more popular and manufacturers are producing more of them so the price has come down close to standard panels. Expect them to be more common.

Definitely pleased with its performance! The standard 200W monofacial was making 115-125 at same temps. 1800W of Hanwha Q cells making 1200W in same temp.

Phillip, I definitely will do a dedicated charging video! Solar charge is preferable because it’s free! But yes I’ll go over some AC powered chargers for these batteries and what voltages and procedures to use! Great suggestion, thank you my friend!

Thank you for all your help.

You’re most welcome!

I’m torn about giving them more airtime but if it will help you, I’ll be glad to test it out! I’ll include it in an upcoming video for you!

@@THEOFFGRIDMOUNTAINHOMESTEAD. Thanks a million:). I live up in Minnesota and looking to power up my shed and this was one of the least expensive self heating batteries available. I was thinking about getting 4 of them. Really appreciate you replying!

You’re most welcome! I’ve got 2 batteries on the test bench at the moment. Might be a week or so before I get to the Vatrer! I’ll also discuss some other generic battery heating options for you during the Vatrer video! Glad to be able to help my viewers! Thanks!

Yes they do hold a little more gravel than a BFG AT style but Wrangler has more of a mud terrain heritage so the wider lug spacing tends to pick up some gravels

I’m in contact with Sigineer, Sungold, and Aims on their 240V split phase models. Sigineer has some nice options coming late summer. I’m going low frequency with this build regardless of brand!

I try to get 2 to 3 videos out per week depending on work schedules! Content has shifted to more of the solar and energy storage topics since starting! Fun to test all the different options out and try to find best products for everyone!
