Prevent Overcharging: Li ion battery protection board is suitable for power charging, which can be used to prevent electric bicycles from overcharging Specification: Item Type: BMS PCB Protection Board Material: PCB Number of Strings: 13S Wiring Mode: Split port Applicable Battery Type: Ternary lithium battery Balance: Yes Purpose: Used to prevent overcharging of electric bicycles Applicable Scene: Power charging Item Details Specification Unit Discharge Continuous discharge current 35(maximum) A Instantaneous discharge current 100 A Charge Charging voltage 54.6 V Charging current 8 (maximum) A Overcharge protection Overcharge detection voltage 4.28±0.05 V Overcharge protection delay 100 mS Overcharge release voltage 4.08±0.05 V Electric quantity balance Cell balance detection voltage 4.2±0.025 V Cell balance release voltage 4.2±0.05 V Cell balance current 60±5 mA Over discharge protection Overdischarge detection voltage 2.55±0.08 V Overdischarge detection delay 50 mS Overdischarge release voltage 3.0±0.1 V Overcurrent protection Overcurrent detection voltage 150 mV Overcurrent detection delay 15 mS Overcurrent protection current 120±5 A Overcurrent protection release conditions Disconnect load Short circuit protection Short circuit protection conditions External load short circuit Short circuit detection delay 200 uS Short circuit protection release condition Disconnect negative switch Temperature protection(can be set) Temperature protection / ℃ Internal resistance Main circuit conduction internal resistance ≤15 mΩ Self consumption Working current ≤50 uA Sleep current (when the battery is over discharged) ≤10 uA Operating temperature Temperature range -30~+80 ℃ Package List: 1 x BMS PCB Protection Board 1 x Patch Cord Set Note: 1. The Difference Between the Split Port and the Same Port: The default charging current of the split port is 8A, and the positive and negative poles of charging and discharging must be separated; the charging current and discharging current of the same port are the same, and the charging and discharging are at the same positive and negative level. 2. Without Equalization and with Equalization: Equalization is to discharge the high voltage cells with resistors during charging, and wait for the low voltage cells to charge up the voltage to achieve the consistency of each voltage and improve the performance of the entire battery pack. 3. Before installing the protection board, the batteries must be well matched (the voltage difference of each battery is not more than 0.05V, the internal resistance difference is not more than 5mΩ, and the capacity difference is less than 30mAh). The better the battery consistency, the farther the distance can be run. The working performance of the protection board is better. 4. The batteries should be connected in parallel and then connected in series, and ensure that the welding is correct (18650 batteries are spot welded with nickel plates, and other batteries are welded with solder). Do not use screws, it is easy to burn out the IC of the protection board.
