BMS 5S 100A Protection Board

3S 4S 5S 100A Lithium Battery BMS Protection Board Balance Version

It does not charge the battery. It is for battery protection. It performs the balancing function.

     This protection board can be used commonly for 3s 4s 5s. The integrated circuit on the board shows stable performance. It has overcurrent protection, over-discharge protection and overcharge protections. The balance function is available.  The charging current is 60A. The discharge current is 80A. Low resistance mosfets are used. You can use it with 3.7V lithium / Lipo batteries.

Note 1: Successfully start the drill requires 15C-20C power batteries (recommended power battery models: VTC4, VTC4A, VTC5A, VTC6); 0V and 12.6V cable, Use copper wire above 4 mm2 (cannot use nickel plate! ! !).
In successful drill applications;  10C-15C batteries must be used. C: A standard that classifies batteries
Recommended battery models:VTC4, VTC4A, VTC5A, VTC6. The cable thickness must be greater than 4mm2. Do not use nickel plate.
 
Note 2: Strictly follow the wiring of the diagram 0V, 4.2V, 8.4V, 12.6V, do not intentionally short circuit. You must make the cable connection correctly. An incorrectly ordered connection damages the product.

Note 3: For some customers with poor electronic foundation, please explain: Do not mix good battery and poor battery! The closer the capacity/internal resistance of the 3 batteries is, the better! (The effect of 2 good batteries + 1 poor battery) = 3 use of poor battery).
For users with an insufficient electronics background; do not use good and bad batteries together. When you use a bad battery (worn out, degraded performance), the total performance of the system drops to the level of the bad battery.
