Review on 🔋 Premium 5PCS 1S 3.7V 4A 18650 BMS Charger PCB Protection Board for Li-ion Lithium Battery Cells by Maria Gray

Building a ham radio project that requires a rechargeable battery using three 18650 Li-ion batteries and a battery management system for protection/charging. I searched and ordered several before I found this one. These were the only ones that didn't break down when plugged in because the others I got had completely wrong wiring information. This model had a wiring diagram on the vendor's Revain page showing exactly how the batteries and charge/output wiring should be connected. Once installed, this BMS system did a wonderful job of charging/balancing single cells with a 11.7V Li-ion charger. I've only used 2 of the 5 boards that came with it, but am already thinking of a few more projects that would benefit from the remaining 3 boards. I will definitely buy more if needed! Aubrey Sheldon
