Feature: 1. Multiple Protections: The battery protection board has built in smart chip with protection functions such as overcurrent, overvoltage, high temperature, short circuit, etc. 2. With BMS Solution: Integrated BMS solution, with the advantage of a single chip to control multiple strings of lithium batteries. 3. Using MOS Tube: Special high efficiency MOS tube, the lower the internal resistance, the less loss, and the stronger the power. 4. Resistance Heat Release: Use resistance heat to release the extra power of high capacity batteries to achieve the purpose of balancing and extend battery life. 5. Aluminum Alloy Heat Sink: Use aluminum alloy heat sink to quickly dissipate heat and ensure the safety of components. 6. For Electric Equipments: Can be applied to supporting lithium batteries for electric tools, electric scooters, electric motorcycles, electric tricycles, electric vehicles, etc. Specification: Item Type: Lithium Battery Protection Board Protection Function: Overcharge, overdischarge, overcurrent, temperature control, balance protection, etc. Overcharge Protection Detection Delay: 1S Balance Current: 30mA±5mA Detection Delay: 1S Over Discharge Current Protection Detection Delay: 1S Release Condition: Disconnect the load Short Circuit Protection Trigger Condition: Short circuit of external load Detection Delay: ≥250us Release Condition: Disconnect the load Temperature Control Protection Temperature During Charging: <-5℃, >50℃ Temperature During Discharge: -20℃-75℃ Self Consumption Working Power Consumption: 100uA Sleep Overdischarge Power Consumption: 20uA Temperature Range: -40℃-80℃.
