LiitoKala 20-cell 3.7V Ternary Lithium Battery BMS Electric Vehicle Battery Protection Board, 20S...

1. Designed specifically for 20S 72V ternary lithium batteries (Li-ion / NiCoMn), suitable for high-power electric motorcycles, heavy-duty electric tricycles, four-wheeled low-speed electric vehicles, RV auxiliary batteries, and medium to large-sized home energy storage systems.
2. Supports continuous discharge current up to 50A and continuous charging current up to 25A.
3. Adopts a common interface design, sharing the same interface for charging and discharging. The PCB uses 2OZ thickened copper foil, resulting in stronger overcurrent capacity and lower internal resistance.
4. Equipped with a disconnection protection mechanism. When any cell in the battery pack fails, or any voltage acquisition cable is accidentally disconnected, the BMS protection board will immediately trigger and cut off the circuit, entering a safety protection state to eliminate potential safety hazards from the source.
5. Built-in mature and stable integrated circuit (IC) control scheme, supporting battery balancing function and automatically correcting individual cell voltage.
6. Provides high-precision overcharge and over-discharge protection, significantly extending the lifespan of high-voltage battery packs.
7. Surface covered with a large area of ??blue anodized aluminum heat sink, with extremely high heat conduction efficiency, maintaining ideal operating temperature even under high-load continuous discharge.
8. Includes a matching 20S color-coded voltage acquisition cable; the socket structure is compact and shockproof, preventing it from falling off.
