Enerkey BMS 6S 120A Lithium Battery Protection Board Compatible with Li-ion/Lifepo4/Lto/SIB Battery Pack
Product Description
1. This series of lithium battery protection boards is a power
management system (BMS) tailored for ternary lithium batteries.
2. This series of lithium battery protection boards uses
automotive-grade MOS, 2oz thickened copper foil and copper strips
for current sharing, making the protection board highly precise,
with ultra-low internal resistance and ultra-low heat generation.
3. On the basis of basic protection board functions such as
overcharge protection, over-discharge protection, over-current
protection, over-temperature protection, short-circuit protection,
etc., a balancing function, reset function, electrostatic
protection, dust-proof protection and moisture protection are
added.
4. This lithium battery protection board (EK-BM3R8S120A) adopts
3S/4S/5S/6S/7S/8S integrated solutions. You can flexibly select the
required number of strings according to the wiring diagram provided
by our company.
5. It is mostly used in the battery packs of electric scooters,
electric bicycles, power tools, car washers, small household
appliances, model aircraft and other products. Mainly plays the
role of protecting the battery pack.
Frequently Asked Questions (FAQ)
Q: Does it support iron-lithium batteries?
A: Yes, the overcharge protection can be adjusted to 3.65V (default
ternary lithium parameters, need to be customized with notes).
Q: Can it be used in parallel to expand the current?
A: Parallel connection is not supported, but a 200A version can be
customized.

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!
