3S 4S 12V 100A Lifepo4 Lithium Battery Protection Board With Power Battery Balance/Enhance Pcb Protection Board

Description: 4S 14.8V Lithium Battery Protection Board with Balancing Function and Matching Connection Cable, Delivers All-round Protection for 18650 Li-ion Battery Packs to Extend Battery Service Life and Guarantee Usage Safety Features: 1. Reliable Voltage Protection: High-precision integrated circuit mounted on flame-retardant FR4 fiberglass PCB accurately monitors voltage of each single cell, automatically cuts off charging/discharging circuit when overvoltage or undervoltage is detected, effectively avoids battery damage caused by abnormal voltage and prolongs overall battery pack life by more than 30%. 2. Fast Fault Response Protection: High-conductivity copper conductive terminals plus built-in high-sensitivity current sensing resistor triggers protection within 10 milliseconds once overcurrent load or short circuit occurs, fully guarantees safety of battery-powered devices and prevents safety accidents such as fire caused by battery failure. 3. Excellent Heat Dissipation Performance: Thickened one-piece aluminum alloy heat dissipation shell rapidly transfers and dissipates heat generated during high-current operation, keeps circuit working within safe temperature range, ensures stable long-term operation even under 35A continuous high current load and fits for high-power application scenarios. 4. High-efficiency Cell Balancing: Professional built-in equalization control circuit automatically adjusts charging current of each cell to keep voltage of all cells at consistent level during charging process, improves overall capacity utilization rate of the battery pack and brings longer endurance for your powered devices. 5. Easy Plug-and-play Installation: Pre-tested 6-core PVC insulated connection cable with standard JST connector supports direct installation without extra soldering or complicated wiring work, greatly reduces assembly difficulty for both DIY enthusiasts and professional maintenance personnel and saves your installation time.
