3S 12V 25A 18650 Lithium Battery Protection Board

This is a 3S 12V 25A 18650 Lithium Battery Protection Board with a balanced circuit, overcharge/over discharge overcurrent, short circuit protection function, and 11.1V/12.6V high current. The board has a balanced circuit and uses the same port for charging and discharging.
Even after removing the charger, some of the heat from the charge balance will remain in the board, causing it to warm up until it falls below the equilibrium break level.

Iron lithium polymer batteries (or any other battery, regardless of material, as long as the overvoltage and high voltage can be used for cutting), electric finish machinery, electric bicycle batteries, vehicle starting batteries and motorcycle starting batteries are not compatible with the protection board.

The following products (within the rated power range) are eligible for this: 12V standby power electronic products; car washing pump; battery; solar street lamp monitoring standby power supply; electric drill; 775 motors (6A-10A); small power inverter; small power vacuum massager battery; LED lamp; and other products.
The maximum rated current is 25 A, and it cannot exceed 50 A in 0.5 seconds.
