4 Series 15 A 18650 Lithium Battery Protection Board 14.8V

4S 15A BMS 18650 Li-ion Lithium Battery 4 Leaf protection device and charge balancer for lithium elements of type 18650 is essential for safely charging lithium-ion elements.

The model in question can manage and stabilize the charge of a group of 4 cells; monitors the individual voltage of the cells by limiting the current in the element to a charge level higher than another, allowing the perfect balance of the voltages of the individual elements and interrupting the flow of current during the fault conditions, overheating and short circuit.

Specifically for robotic applications and devices in general, which require an accumulating battery with the critical operating current.
