Best not to post a Zip file.... as I agree with SJ.

So... Will. Are you up to the task of seeing what makes up and Antigravity battery? I did some searching and do not find too much about them. Just a thought, thanks.

Well, realistically they should be the same. But actually it really depends on the maximum current that is expected to flow. So, as long as the smallest combined group of wires handles the load, then it really does not matter.

Yes, that is how I have it. I just have them labeled... but essentially, on the far right is negative connection for BMS' and left is positive, both banks in parallel.

Here are a couple of pictures of my install. 2 banks of 12vdc of 280ah each bank. Things are tight, but it all worked out.

I have two banks of four 280ah cells (12v), each with a 120 amp Overkill Solar BMS. My question is, why do they not load balance? I had one giving out 10amps and the other 1amp. What am I not understanding? Thanks

I would string them out like you show. I would also limit your charging to about 3.5v or less per cell. You will probably have a bit of expansion, but considering your load, should really not be a real problem. The cells will probably not last as long if not compressed, but I think they will...

Thank you for the replies.... this confirms what I was thinking... that I should go to a higher voltage.

I am only planning to have my cells go up to 3.375 v. So I am top balancing them to this voltage. My question is... is this an acceptable practice? Or should I go to a higher voltage? Are there pros and cons to balancing at a lower voltage? If I am going to set my BMS to a max cell voltage...

Yes and no..., I will have less than 50amp load on it and less than 25amp charge for it. I will have to see how it works out and make changes if necessary. This will be covered out of the elements (but very unlikely a possiblity of water getting splashed nearby), so if necessary, I will...

I have installed my BMS in a "water proof" box... as you can see in the pictures. I think it worked out fairly well.

I have found a plastic water proof box that I plan to mount my OverKill BMS within. It is a 7.9 x 4.7 x 2.2 inch box and I will be using glands to run the cables through, thus no air circulation and such. My configuration will be two banks of 280aH batteries with two Overkill BMS, each in...

I picked up from the Houston warehouse last week 8 EVE 280aH cells and brought them back to Tampa. All in great shape and all about. 3.3vdc each. I am currently topping them off and balancing them for my project to replace my AGM batteries in my RV. Amy was great to deal with and the pickup...

Well, should negotiations fail with the boss, I can quit being the driver and the boss goes nowhere. So, I pick the battles based on weapons on hand. Based on what I think, with the capacity I am going to.... I think I will be good for a long while.... I have found a flat waterproof box...

I would have considered that... but the boss is unwilling to give space. I can lock my battery box, so that helps. As far as temps go... yes, but at different times it gets hotter inside than outside. Cold is not a problem. If it becomes so, I have a DC warming pad that I can place in the...

Thank you, this helps a lot.

No ReBel batteries. Batteryhookup is out of stock and the one they have only supports 100ah, I am wanting a bit more.

Can anybody tell me the height/length of the EVE 3.2V 280Ah cell with a terminal/stud/bolt installed? I have a very close tolerance I need to work with and do not know the stated spec of 202mm/7.95" includes the studs/bolts? Thanks for the help...

Bob, That is what I am currently now working on.... I am in contact with Amy regarding price and availability in Texas. I think I wanted CATL batteries, but they are out of stock. She only has EVE. not sure I should be concerned... but... And then I am trying to figure out which BMS...

Well.... the real reason is I am a damn geek and electrical engineer.... and I just always seem to want to know what is going on. Do I really need it... no, but.... Did I tell you I am a geek? But now, if I try to use SOK's, I can put only one in my battery location and would have to put...

I am looking for answers, thoughts and comments on my RV battery project. Summary: I have a metal battery box welded on the front frames of my travel trailer. It has a hinged cover and though not water proof, water would not splash directly on the enclosed components. The size of the box is...

Well... I now think I am on to figuring out a different approach... as it appears SOK does not give you anyway to REALLY monitor what is going on with their stuff. I had high hopes for them, but not now!

Yes, it shows them to be very good batteries... but I yet see how to get any information on what is going on inside. Other BMS systems have Bluetooth were you can go and get all sorts of information on what is going on inside of the battery... like individual cell voltages. But can you get...

I am considering getting some SOK batteries... I like what I see about them EXCEPT I do not see how you can really monitor them and see what all is going on with the individual cells and.... When a questioned SOK.... they just sent me a link for a shunt and a monitoring system, NOT helpful...
