Energy Storage Bms 6S 7S 50A Lithium Battery BMS Protection Board With NTC For Electric Tricycle Cell Bms 24V
Over-current protection: When the battery discharge current or charging current reaches the first level of over-current, a warning message will be issued, and when the current reaches the second level of over-current, Enerkey BMS will automatically disconnect the power supply.
Short-circuit protection: When the circuit is short-circuited, the current increases instantaneously, and Enerkey BMS will automatically disconnect the power supply
Application fields: medium and large current power batteries such as AGVs, industrial vehicles, forklifts, high-speed electric motorcycles, golf carts, low-speed four-wheelers, etc.
The status management function is powerful, and each product undergoes strict quality testing before leaving the factory, including insulation testing, current accuracy testing, environmental adaptability testing, etc.
BMS monitors battery cell voltage, battery pack total voltage, battery temperature, charging current and discharging current in real time.

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!
