Lithium battery protection board designed for outdoor power supplies, inverters, UPS, car emergency power supplies, and other energy storage devices. Built with onboard low-resistance MOSFETs and thermally conductive silicone pads for heat dissipation during 100A high current operation. Includes disconnection protection function for battery pack. High Current Capacity: Maximum continuous current of 100A. Disconnection Protection Function: Automatically cuts off the output when a cell connection is abnormal or the cable is disconnected. Protection Functions: Overcharge protection, over-discharge protection, overcurrent discharge protection, short circuit protection, and temperature control protection. Parameters: Number of cells: 3 cells (3S), suitable for 12V/12.6V/14.6V platforms. Overcharge protection: Detection voltage for a single cell is 4.225±0.05V; release voltage is 4.15±0.05V. Over-discharge protection: Detection voltage for a single cell is 2.75±0.05V; release voltage is 3.0±0.1V. Balancing parameters: Detection voltage: 4.2±0.025V; Balancing current: 42±5mA. Continuous discharge current: 100A Charging current: ≤30A Main circuit conduction resistance: ≤10mΩ Operating temperature range: -30℃~+80℃ Color: Yellow Material: PCB Package Contents: 1 x Protection Board, 1 x Cable (Color may vary). Note: Colors in images may vary due to light reflection and display settings. Measurement tolerance +/- 1-3cm.
