BMS Board 3S 30A Balanced Version 11.1V 12.6V

New BMS Board 3S 30A Balanced Version 11.1V 12.6V

Scope: Suitable for lithium battery with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer battery, no size limit)

Product size: 41*50*3.4MM (standard) 41*55*3.4MM (equal)

Charging voltage: 12.6V-13.6V

Continuous discharge current (upper limit): 30A If the heat dissipation environment is not good, please reduce the load current.

Continuous charging current (upper limit): 20A

Equilibrium version: Suitable for electric drills with starting current below 60A, power below 130W, or resistive load below 378 with balanced charging function.


Note 1: Three 10C-20C power batteries or six 5C-10C power batteries are required to successfully start the drill (recommended power battery model: VTC4 VTC4A VTC5A VTC6)

Note 2: Strictly follow the wiring of the diagram 0V, 4.2V, 8.4V, 12.6V, do not touch any components on the board when soldering the wire, do not intentionally short circuit

Note 3: When soldering the battery for the first time or charging, as long as the single battery exceeds 4.2V, the 430 resistor will heat up and discharge (discharge to about 4.19V to stop heating). If the 430 resistor is severely heated (heat is not enough to touch, please check if the wrong line is connected)
