3S 11.1 12.6V Battery Charging Module PCB BMS Protection Board For 3 Series lithium LicoO2 Limn2O4 18650 26650 battery (5A)

Product description: A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and balancing it.

Specifcation: 1. 3 string (for 3 18650 batteries or polymer lithium battery series combination) 10.8V (rated voltage for polymer battery) 11.1V (18650 or 3.7V lithium battery rated voltage) 12.6V (lithium battery is fully charged after the voltage) Overcharge detection voltage: 4.25-4.35V±0.05V, Over-discharge detection voltage: 2.3-3.0V±0.05V 2. Supply Voltage: 12.6V, Over-discharge recovery voltage: 2.5v ± 0.05v, over-discharge-delay-time: 144ms 3. Maximum discharge current: 10A, Maximum working current: 5A-8A, Transient current: 9A-10A, Quiescent current: <6uA 4. Internal resistance: 30,000hours, Please not the board color may vary between red, blue and green based on availability 5. Short circuit protection. Overcharge protection. Over-discharge protection. Overcurrent protection. Can be applied to various 3.7V lithium core. Compact size and lightweight. Ensure the security of battery pack

Note: 1. The successful start of the drill requires three 15C-20C power battery, or six 10C-15C power battery (ordinary 18650 can not start the drill). 2. strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit. 3. When the load of the brush motor is used, try to connect a non-polar capacitor (withstand voltage above 25V, capacity 10uF-100uF) to the motor's positive and negative terminals to prevent the reverse spike from the motor. Break the MOS tube. 4. 3 groups of batteries in series, please ensure that the voltage of each group of batteries, if not the same, please fill each battery separately and then use in series. In Discharge test, the battery that has faster voltage drop is poor battery. 5. Balanced charge is only auxiliary functions, try not to put a good battery and poor battery mixed together. 3 sets of battery capacity / resistance closer to the better! (2 good battery +1 Poor battery use effect = 3 poor battery use effect).
