Review on πŸ”‹ DZS Elec 2PCS 2S 18650 Lithium Protection Board 7.4V 8.4V 8A BMS PCM Charger Protection Board for Li-ion Lithium Battery Cell with Enhanced SEO by Barb Cook

Revainrating 4 out of 5

Balance the batteries before connecting.

Missing information, hence only four stars. For those having trouble, make sure the two batteries are balanced and not at full capacity. Then charge the batteries through the BMS, then your BMS will work properly. I went through a bunch of them thinking they were all bad until I found some good documentation about them. They are designed to stop working if the batteries are too badly unbalanced.

Pros
  • Few competitors
Cons
  • Unreliable
