Review on 🔋 VNSZNR BMS 4S 40A 12V LiFePO4 Lithium Battery PCB Protection Board with Balance Leads Wires: Ideal for 18650 LiFePO4 3.2V Cells Battery Pack by Cody Cobbs

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 why they don't hire anyone to look professional. But at least they contained something. It also comes with a schematic that most people will need. Even in colour. So far very satisfied, great price for size and quality, happy to recommend.
