Balanced Version 4S 40A Lithium Battery Protection Board BMS Lipo Charger Module

 

Description

1. Scope of application: Suitable for lithium batteries with a nominal voltage of 3.7V and a full voltage of 4.2V (Including18650,26650, polymer lithium batteries, no restrictions on the size)
2. Product size: 45 * 60 * 3.4mm
3. Charging voltage: 16.8V ~ 18.1V
4. Continuous discharge current (upper limit): 40A (if the heat dissipation environment is not good, please reduce the load current)
5. Continuous charging current (upper limit): 20A
6. Suitable for electric drills with starting current below 80A and power below 230W, with balanced charging function.

 

Note 1: Successful start of electric drill requires 4 10C-20C power batteries, or 8 5C-10C power batteries(recommended power battery models: SONY VTC4, VTC4A, VTC4A, VTC6), 0V and 12.6V connecting cables, Use copper wire of 3 mm squareor more (no nickel sheet !!).

 

Note 2: Connect 0V, 4.2V, 8.4V, 12.6V, 16.8V strictly according to the figure. When welding the wire, do not touch any components on the board. Do not intentionally short circuit.

 

Note 3: When welding the battery for the first time or charging, as long as a 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 extremely hot (not hot enough) (Dare to touch), please check whether the wrong wire is connected.
