The protection board size and device description;
The size of the protective plate is 46.7 * 23 * 3.15mm
Welding point Description:
B + connected to the battery positive;
B-connected battery negative;
MB connects the battery 1 to the connection point before the battery 2;
P + connected to the charge / discharge side of the positive (charge side / discharge side shared);
P-connect / discharge terminal negative (shared with charge / discharge).
Tips: the battery pack when the battery voltage, capacity, internal resistance must be a good match, the battery voltage in the rated voltage of about 3.7V appropriate, the group did not output a good battery pack, with 8.4V voltage can be charged.
