Overview1.Sepecification Battery Type: Li-ion / LiFePO4 /LTO (Please choose the right model for your battery type) Type and Strings: R10K( 3S-10S), R24K (11S-24S) Current Range: 40A/60A/100A B-P- Cable Specification：10AWG(40A/60A) 7AWG(100A) High Power Pre-charge: With pre-charge function Parrallel Current Limiting: Build-in parallel current limiting module Software Features: APP/PC/IOT Balance Mode: Passive balance Balance Current: 100mA ±30 Data Storge: EEPROM 512Kb Communication Interface: UART x2 , RS485 x 1 , CAN x 1 SOC: using current initegration method Operating Tempreture: -40~85℃ Ralative Humidity: 5% -90% RH 2. Product Dimensions Product Size: L * W * H (mm) = 125*65*13 mm, 180g 3. How to select the BMS for your battery pack ? A. Battery Type Compatibility: LFP or Li-ion or LTO Battery Pack. B. Number of Cells in Series (S) ：For example, for a 4S battery pack (four cells in series), the BMS must select the 4S. C.  Current Rating (Discharge and Charge Current)：For example, if your battery can discharge at 60A, your BMS must support at least 60A continuous discharge. Also you can add a margin (e.g., 20–30%) for safety. D. Balancing Functionality: Passive Balancing: Dissipates excess energy as heat OR Active Balancing: Transfers energy between cells. E: Communication Features : CAN, UART, Bluetooth Module, Wi-Fi Module(Optional).
