48V 14S BMS Protection Board for Ternary Lithium Batteries with Cable, 8A Charge/20A Discharge Balancing Module

Welcome to our shop! This lithium battery protection board is an essential component for ensuring the safety and performance of your batteries. Designed with a smart chip, it incorporates multiple protections against overcharging, over-discharging, overcurrent, short circuits, and temperature. It uses an integrated BMS solution, allowing a single chip to manage multiple battery cells in series. It is equipped with a high-efficiency MOS transistor, offering low internal resistance to minimize energy loss and deliver optimal power. A resistive heat dissipation system balances the charge of high-capacity batteries, thus extending their lifespan. An aluminum alloy heat sink ensures rapid cooling for component safety. Ideal for equipping lithium batteries in power tools, scooters, motorcycles, tricycles, and electric vehicles. **Technical Specifications:** **Type:** Lithium battery protection board.** **Protection Functions:** Overcharge, over-discharge, overcurrent, temperature control, balancing.** **Charging Voltage:** Number of cells in series x overcharge voltage (4.2V for ternary lithium-ion).** **Nominal Voltage per Cell:** 3.7V.** **Overcharge Protection:** Detection at 4.25V±0.05V (1s delay), recovery at 4.15V±0.05V.** **Balancing:** Activation at 4.18V with a current of 30mA±5mA.** **Over-discharge Protection:** Detection at 2.7V±0.1V (1s delay), resets to 3.0V±0.1V.* **Overcurrent Discharge Protection:** 1s detection delay, resets after load disconnection.* **Short Circuit Protection:** Detection in ≥250µs, resets after load disconnection.* **Thermal Protection:** Charging prohibited below -5°C and above 50°C.
