Main function:

Over charge protection, over discharge protection function, short circuit protection
function, over current protection function, band 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 all over the hole, the hole diameter of the pad is 3.5mm;
The battery charging detection interface with DC output in the form of needle. Do the same mouth
when the N- is not wiring.
