Using a protection board to connect an LED display can more intuitively monitor changes in battery parameters and more effectively battery safety. Efficient heat dissipation,The metal heat sink dissipates heat more efficiently, continuously protects the battery and ensures efficient operation of the battery. Supports two parameter adjustment methods: APP and computer, you can freely choose the adjustment method. Smart Bluetooth APP is connected to adjust parameters, realize collection, reading, viewing, analysis settings, battery real-time data and historical alarm records, etc. Type: Smart charging only Battery pack quantity: 65-285 Discharge current: 150A Bluetooth function: with Bluetooth, support Android Voltage support range: 15V-118V Shutdown power consumption: Less than 80UA SOC estimation accuracy: error 8% Standby power consumption: Less than 100UA Charging temperature reset: 0-100 Size:112.17x33.7x12.8mm Charging current: 12A Short circuit protection: support Battery Chemistry: Lithium Ion/LIFEPO4 Temperature detection: -30-125 Maximum battery voltage: 120V Temperature detection quantity: 4 () Working power consumption: Less than 40MA (UART/CAN) Charging protection temperature: 0-100 Note: For 4.25 battery packs, each S voltage can only be set to a maximum of 28V Recommended operating temperature: -20-+75 Balance: 28MA@4.2V, passive balance Single cell voltage S detection range: 2V-5V, error value: 2MV Connector:A:XT60 Colour:As Shown Material:PCB Package Contents: 1set * charging protection board accessories Only the above package content, other products are not included.
