4S 60A BMS 3.7V PCM Battery Protection Board BMS PCM With Balance for lithium LicoO2 Limn2O4 18650 li Battery Features: 1. Specifically designed for 4-series lithium battery packs, supporting 21700/18650 cells. 2. Maximum continuous output of 60A, instantaneous current up to 110A. 3. Built-in temperature control protection mechanism, automatic power off and cooling at 60℃. 4. With active balancing function to improve battery consistency. 5. Equipped with overcharge and over-discharge protection for more comprehensive safety. 6. High-density PCB layout, strong anti-interference, and more stable operation.

Product Parameters: Overcharge detection voltage: 4.25V Overcharge release voltage: 4.19V Over-discharge detection voltage: 2.8V Over-discharge release voltage: 3V Port specifications: 1.25mm interface Default maximum output current 60A, with temperature controlled charge and discharge protection at 60℃ Uses 6 high-current, ultra-low internal resistance nMOS transistors (single nMOS internal resistance as low as 3.4mR), instantaneous maximum 110A, stable output 40A, heatsink recommended for extreme conditions. The ports on the board can be used to connect the battery balancing wires, or you can solder them yourself according to the wiring diagram. Uses BM3451 as the main control chip, the lithium battery protection board comes with a balancing function, perfectly matching 4S battery packs. Wiring Precautions: 1. Requires a certain level of technical electronic knowledge. 2. The wires connecting to the battery should be short and thick.
