7S Battery BMS With NTC 24V 20A Lithium Li-ion 7S BMS for Base Station Energy Storage
7S 20A BMS 18650 Li-ion Lithium Battery protection device and charge balancer for lithium elements of type 18650 are essential for safely charging lithium-ion elements.
The model in question can manage and stabilize the charge of a group of 7 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 that require an accumulating battery with a critical operating current.

Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.
4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
