Looking for simple LFP-BMS for 8S1P 100Ah battery

[rilonau]

Hello,

i want to build my first LFP battery (for testing purposes) and want to equip it with a rather simple BMS for protection (deep discharge and overcharge) with capability of 40...50 Amps. It doesn't need to have any software or programmable features but should be as efficient as possible regarding power consumption. What can you recommend? Any suggestions welcome!

I strongly recommend one with software and programmable features.

How about: (try to disregard that they cannot spell LiFePO4)

Overkill bms is a good choice with a fantastic warranty

You'll likely receive it a couple weeks sooner too.

Never heard of JDB BMS. What about JK? Imho the simpler the more stable and reliable. Software can be faulty (there was recently a bug/flaw in JK firmware where LFP-settings were automatically reset after a longer idle period back to li-ion without any notice!). I would like to have it as simple, yet reliable and stable, as possible? With software and bluetooth etc. you might have more options and information - right - but is it really needed?
