BMS 7S 50A 29.4V Lithium Battery BMS Board For Ebike Battery Lifepo4 Lithium Ion Battery With Bms

Product Description

A lithium battery’s Battery Management System (BMS) acts like a battery bodyguard. It wards off unsafe situations and helps extend your battery’s lifespan.

  • BMS Three-Fold Battery Protection
  • Your battery (and your investment)
  • Your vehicles/applications
  • You and your family

The battery management system prevents your boat, RV, or other application from being damaged by the battery. It also protects you and your family.

But that’s not all. The battery management system manages your battery’s performance. It measures energy, regulates temperature, and more. This makes it a crucial component of your LiFePO4 battery

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!
