Product Description

3S 12V 25A with Balance Li-ion Lithium Battery 18650 Charger Battery Protection Board 11.1V 12.6V

Description:
The protection board has a function of protection against charging, the function of protection against discharge, current protection and the function of short-circuit protection.
The charge and discharge of the card are the same port, the card is included in the balanced circuit.
When the balance of charge, the card will be a bit hot, even after disconnecting the charger, some are still in balance, they will continue to heat up for some time until the equilibrium break threshold.
The protection card can not be used for the lithium polymer polymer battery (for other batteries, regardless of the material, as long as overvoltage and discharge voltage can be used for cutting), electric fish-machine batteries, batteries electric bicycles, protection.

Applicable to the following products (within nominal power):
Electric drill, motor 775 (6A-10A), small power inverter, small power vacuum battery, LED lamp, 12V standby power electronic products, 12V120W car wash pump, battery, surveillance solar bulb lamp and other products.
