This is a 4S power range rated lithium-ion 18650 battery management system pack protection board which operates up to 30 amperes of current at 14.8 volts.
The power range described applies to the following products:
Massager battery pack, LED lamp backup power supply, 12V electronic products, solar streetlamp battery pack, monitoring backup power supply, and other products.
Specifications

Short circuit protection function: available: disconnecting the load can cause self-recovery.
Dimensions:45x56mm
Wiring: 12 inch long stranded 22 AWG wires with 5 position female PH JST connector: wire cut, stripped and tinned 1/16” one extremity
Main function:
Over charge protection, over discharge protection function, short circuit protection
function, over current protection function, balance.
Interface definition:
Charging port of the plate and the discharge port is the same, both positive and B- connecting battery"-", P- charging port and port on the negative electrode;
B-, N-, P- pads are full of holes for heat dissipation, the diameter of the pad is 3.5mm;
The battery charging detection interface with DC output is in the form of a needle. Does the same when the N- is not wired.
Note: For products with a current above 3A, the battery discharge rate must be above 3C.
The magnification calculation formula: 1C battery, 2000 capacity is equal to 2AH*1=2A working current.
3C rate battery, 2000 capacity is equal to 2AH*3=6A working current.
The battery will heat up during use, which means that the battery rate is not applicable. In this case, it cannot be used for a long time, and the battery will be damaged quickly.
