I have 16x 280ah REPT cells wired 8S2P with 2x 200a JK BMS, one on each 8S but they are constantly throwing up wrong data. For...

It was about 3.40 when I noticed it bulging. If I can somehow bring the voltage right down that's what I need. How to drain a 3.2v cell...

Fantastic, just what I needed to hear. There's a bomb in my garden! :rolleyes:

How low temperature? At the moment it's outside in the garden. About 25C day and 15C at night.

I purchased 4 cells from china, and after charging one has seriously swollen up. It's voltage is 3.33v. How can I dispose of it? Or...

Yes I do mean batteries. I don't have a problem putting them in parallel I'm just wondering how I would wire up the two BMS. Which...

Well that's me convinced. Thanks very much!

You lose single cell monitoring. You cut your current to the limit of ONE BMS rather than most of the two. You lose redundancy - if one...

I have 2x JK 200a BMS which ive been using for a while. I will just connect the 2 cells in parallel and continue. Does anyone have a...

A 16S bms is for 48V. Two cells in parallel are a single cell. Connect them in parallel as two separate 8S batteries each with their...

Yes of course you're right. But what about if I put 2 cells in parallel and just use one BMS?

I have 2x 8S 24v 280ah LifePO4 battery packs which I want to combine to create 1x 24v pack. I have 2 separate BMS which are 24v 8S...

Can anyone tell me what size the 300a red wire would be?? Black wire is 25mm2 and the red is roughly double.

No not Alaska. AK is the first two letters of my surname. I live in southern Spain.

Yeah after I clicked submit I realised they are simply two wires crimped together into one. It's just difficult to find the wire size...

Buy a good crimper and make them yourself. Two wires reduces the amperage on each wire. Smaller wire is less strain on the connection...

I bought a battery box 'kit' from Alibaba which came with a 200a BMS, and these 25mm2 thick wires and an even thicker positive wire...

Yeah so my 200a BMS and 100a charge controller is more than enough. Even this time of year it's giving me 1200w, 6 hours a day.

If you used 280AH cells, they can discharge at 280A for 1 hour o take 140A Charge for 2 hours. The JKBMS default is too low and many...

It is, but i have absolutely no idea yet how to do that. (I've only had them a few days). For now, ive set the inverter max 60a.
