Electronic Car Lithium Battery BMS

Product Description

Enerkey BMS 3S 4S 50A Lithium Battery BMS Board Li-Ion Battery Protection Board For Electronic Car 

Product Description

This lithium battery protection board (EK-B3Sr4S50AR) adopts 3S and 4S integrated solutions. The required number of strings can be flexibly selected according to the wiring diagram provided by our company.
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.

 

Because overcharging, over-discharge, and short circuits of lithium batteries may cause the battery to be scrapped. The BMS plays a protective role. During use of the lithium battery, every time it is overcharged, over-discharged, or short-circuited, the battery will be reduced. life.

In serious cases, the battery will be scrapped directly! If there is no lithium battery protection board, directly short-circuiting or overcharging the lithium battery will cause the battery to bulge, and in severe cases, leakage, decompression, explosion, or fire may occur.

In general, the BMS acts as a bodyguard to ensure the safety of the lithium battery.

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!
