12.6V Lithium Battery Protection Board

Lithium Battery Protection Module / Battery Management System (BMS)

Protection Modules or Battery Management Systems are used to safeguard and control the charge and discharge of Lithium-Ion or Lithium-Polymer Batteries. These modules are typically categorized based on their current capacity and the number of battery cells they support.

This particular Lithium Battery Protection Board functions as a charger for single-cell lithium cobalt oxide, lithium cobalt, lithium, or lithium polymer batteries, with a maximum charging capability of 40 A. Key features include overcharge and discharge protection circuits, which prevent damage to the Lithium Battery.

The board also includes high-precision voltage detection and internal overcurrent detection. Additionally, MOSFET transistors allow the Battery Protection Board to effectively control both charging and discharging operations. 

Connection Instructions:

• B+: Connect to the positive terminal of the battery
• B1: Connect to the junction between Battery 1 and Battery 2
• B2: Connect to the junction between Battery 2 and Battery 3
• B-: Connect to the negative end of the battery
• P+: Positive terminal for charging/discharging
• P-: Negative terminal for charging/discharging

This Lithium Battery Protection Module ensures safe operation while maximizing the performance and lifespan of your Lithium Battery system.
