LiitoKala 4S 12V 100A BMS LiFePO4 Battery Protection Board Balanced Charging Lithium Iron Phosphate Battery Management System

Features:

1. Comprehensive Protection Mechanisms This module offers comprehensive protection, including overcharge protection, over discharge protection, overcurrent protection, short circuit protection, and temperature control protection. These extensive features ensure the safety and longevity of connected batteries.

2. High Discharge and Charging Currents The module supports a discharge current of up to 100A and a charging current of ≤60A on the same port. This high current capacity makes it suitable for demanding applications where quick charging and high-power discharge are essential.

3. Advanced Equalization Functionality The advanced equalization functionality ensures balanced cell voltage by detecting voltages at 3.5±0.025V and providing an equalization current of 30±5mA. This helps maintain battery health and optimizes performance.

4. Low Power Consumption With a working power consumption of ≤40µA and sleep over discharge power consumption of ≤10µA, the module is designed for energy efficiency, minimizing battery drain even when the system is idle or in sleep mode.

5. Robust Design for Extreme Conditions The module operates efficiently in a wide temperature range of -20°C to +80°C, making it ideal for various environmental conditions. The short circuit protection with a quick response time of ≤300µs further enhances its reliability under extreme scenarios.

1. First connect the B- wire to the total negative electrode of the battery (be sure to weld the short wire of the B- wire), and then connect the bar wire (before connecting the bar wire, be sure to remove the bar wire from the board).

2. Connect cables from B-, where B- connects to the total negative terminal of the battery, the second line B-l connects to the positive terminal of the first battery, the third line B-2 connects to the positive terminal of the second battery, and the fourth line B-3 connects to the positive terminal of the third battery..... And so on

3. Finally, measure whether the total voltage of the battery is equal to the output voltage of the protection board. Equal protection board is working normally.
