7S 20A 24V Li-ion Lithium 18650 Battery BMS Packs PCB Protection Board With Matching Cable Automatic Protection Function

7S 20A 24V Li-ion Lithium 18650 Battery BMS Packs PCB Protection Board With Matching Cable Automatic Protection Function

Discharge products with above 3A current, battery discharge rate should be more than 3C.

Magnification calculation formula: 1C rate battery,2000 capacity equals 2AH x 1=2A working current;3C rate battery,2000 capacity equals 2AH x 3=6A working current. Short circuit protection, delay self-recovery, provides overcurrent, overcharge and over discharge protection.
