3S 12V 25A 18650 Lithium Battery Protection Board

214.00 Excluding tax

Spread the components
This is 3S 12V 25A 18650 Lithium Battery Protection Board 11.1V 12.6V High Current With Balanced Circuit Over Charge Over-Discharge Over Current And Short Circuit Protection Function. Board charging and discharging are the same port, the board includes the balanced circuit. When the charge balance, the board will be a bit warm, even after disconnecting the charger, some are still in the balance, will continue to warm for a while until below the equilibrium break threshold.
The protection board cannot be used for iron lithium polymer battery (for other batteries, no matter what material, as long as the over voltage and put voltage can be used for cutting), electric finish machinery, electric bicycle batteries, car, and motorcycle starter battery protection.
Applicable to the following products (within rated power): Electric drill, 775 motors (6A-10A), small power inverter, small power vacuum massager battery, LED lamp, 12V standby power electronic products, 12V120W car washing pump, battery, solar street lamp monitoring standby power supply, and other products. Rated current cant over 25A, it cant exceed 50A per 0.5 seconds.
