Features:
Protection circuit board is the heart of battery
pack, must to have to
avoid battery pack from explosion, fire and damage. 
It will protect battery pack from overcharging,
over-discharging over-current and short circuit.
The protection board with balance has equilibrium function to keep each cell in balance and good service life.
Choosing the correct protection board and applying it appropriately is vital to the longevity your batteries.
Quiescent current＜ 30uA, so power consumption is small.
