Description

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.

Trust Endorsement
CE/FCC/RoHS certified, PICC insures product liability insurance.
Cumulative shipments have exceeded 500,000, and cooperative customers include XX electric vehicles and XX energy storage brands (LOGO walls can be placed).

Application compatibility
• Applicable scenarios: electric vehicles, energy storage systems, industrial equipment (such as AGV robots)
• Applicable battery types: ternary lithium/lithium iron/lithium titanate/sodium ion battery packs (parameters need to be adjusted according to the number of strings)

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!
