Recommendations for a BMS that can be put in series (12v)

[gilcontr]

Hi, can anyone recommend a BMS that can be placed in series 12v-24v? I have 2 280a eve battery packs. Only problem is that they are different generations and the dimensions are different. Noone is buying the batteries, so the next best thing is to place them in series. Going to use them with a 24v growatt

Thanks!

Get a 8s bms (24v) rather than two 4s bms. That way the lowest cells control the whole battery. It really won’t save you anything by having two 4s bms’s (unless you want to keep the option of using them as 12v batteries in the future).

I used 4s Overkill bms in a small battery I made and like it. I believe it can be hooked up in series - but check with them.

I've been running 2 of these in series for 24v.

Thanks! Are you running the 150 amp?

Looks like I ordered the 100amp since the cells were only 100ah.
