2Pcs 3S 11.1V 12V 12.6V 60A with Balance 18650 Charger PCB BMS Protection Board Li-ion Lithium Battery Charger Protection Board Balance Charging Module for Drill Motor

Used on a 10ah 12.6 lifepo4 battery, soldered to the battery leads and double sided taped to the battery in a case. Charge terminals wired to a small solar charge controller. Easy build, extremely useful. Haven't had any issues yet, very reliable. Folks if your board is overheating or failing, the 60 amp rating is not for charging. And if you don't know that you should be paying for new boards don't fault the product.

After getting DOA boards that couldn't be returned, it was pleasant to receive these 2 perfectly working boards. Awesome! 5 stars! Thank you! Charges to 12.6, handles loads within parameters, and small enough to fit in 18650 holder space.

I've had problems with some BMS 3s. These work perfectly. I don't use them at more than a few amps. So the 60Amp rating seems a little crazy. But for 5 amps these work.

Good

One of two boards arrived defective, and the other popped instantly when I accidentally shorted the battery terminals while connecting a load. Don’t depend on these for short-circuit protection. They also get quite hot, but they do basically work when they work.

Funciona bien

I recently ordered these BMS boards for my project and the last items I got have defect. One does not load on higher current and the other board will not detect and stop the battery discharge voltage. I believe those boards have never gone through any inspection at all. This is 50% of the devective boards I received from them!

works well, if installed properly
