3S 40a Lithium Battery BMS Protection Card Enhanced Battery Li-ion 18650 12.6V Suitable for 3 pcs series 18650 batteries.

Battery does not charge.

For battery protection.

3 x 15-20C batteries should be used in drills.

Or 2x3 10c-15C batteries should be used.

Standard 18650 batteries cannot be used in applications such as drills.

The battery connection is shown in picture 2.

3 battery groups can be connected in more than 1 parallel.

Incorrect connection will damage the product and batteries.

Enhanced Edition: Suitable for starting current below 80a, power 135W below the drill.

With this module, you can quickly charge high-capacity 3S lithium batteries. Thanks to the voltage protections on it, it protects your batteries from charging at high voltages and prevents damage to the batteries by preventing them from drawing current from your batteries that are about to run out.

Batteries must be charged at limited currents.

Charging the battery without current control will reduce the life of the batteries.

Similarly, rapid withdrawal of high current from the batteries will damage the batteries.

Although BMS products seem to charge batteries, they do not perform current control.

It is suitable to be used only for protecting the batteries.

You need to charge your bms cards and batteries with a current control source.

Battery charging current should be at levels such as 1/10 2/10 of battery capacity.

Remember that charging or discharging too high current will reduce battery life while saving time/power.
