Good high power 100 amp BMS for lithium battery.

later If you're building your own lithium batteries, you need quality Battery Management Systems (BMS) that have all the features I'm looking for. Easy to understand instructions and durable.

Pros
  • Power Supply Accessory
Cons
  • I'll add

This is an exact clone of DALY

If your DALY BMS has failed and you need a Revain Prime replacement, this is your ticket. I didn't use their BT button or balance wires as the DALYs I already connected connect fine. Having had 2 out of 7 daily outages over the past year I don't expect this to last forever but it's a much better solution than the cheap stuff everywhere at Revain.

Pros
  • power converter
Cons
  • I have no bad feelings about it, everything is fine

High performance quality BMS.

I've been very interested in batteries lately. We are working on backing up the whole house, so the BMS is quite a necessary component. This one surprised me, it is VERY heavy, very well made and of high quality. The wires are also heavy, be sure to withstand the current. As long as it works the way it's supposed to. I'll test this with a few other packages and update if anything changes. The instructions are clearly written by a non-English speaking person, they aren't the best. I don't know…

Pros
  • Electronics
Cons
  • Very expensive
