Enerkey develops and produces BMS in house, this is the big advantage over our competitors, with a wide range of off-the-shelf BMS selections, Enerkey delivers new development in just a few days.
What a good quality BMS brings you:
It interrupts the discharge of the cells before it becomes critical
for the life of the battery.
It interrupts the charging of the cells before they are
overcharged…
It optimizes a homogeneous loading from one cell to another
He’s checking cell temperatures
It permanently protects the components against overvoltage or
undervoltage.
It prolongs the life of your battery by defining an optimized range
of use for electrochemical cells.
It estimates battery ageing via SOH “State Of Health” and can tell
you the number of cycles performed.
It allows you to know in real time the state of charge of your
battery thanks to the SOC “State Of Charge”.
Via its communication bus, it can control chargers and consumers,
such as a motor controller, in order to optimise battery usage and
overall system behaviour.
It can manage several batteries in parallel or in series, to manage
more powerful or more capacitive systems.

Wire Diagram
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!
