3S 30A 11.1 12.6V Battery Charging Module PCB BMS Protection Board For 3 Series lithium LicoO2 Limn2O4 18650 26650 battery - with Balance Function (30A)
A battery management system (BMS) is an 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.
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!!).
Note 2: strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
Note 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.
Note 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 the Discharge test, the battery that has a faster voltage drop is poor battery.
Note 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).
Suitable for 3 string 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)
Charging voltage: 12.6V - 13.6V, overcharge detection voltage :4.25±0.025V overcharge Lift the voltage:4.15±0.05V over-discharge detection voltage :2.50±0.08V over-discharge Lift the voltage:3.00±0.1V
Continuous charge current (upper limit): 40A; Continuous discharge current (upper limit): 60A (if the cooling environment is not good, please reduce the load current use) (Natural cooling 15A, add heat sink 20A and above), Maximum instantaneous current 40A
Internal resistance: Less than 45 m Ω, Service life: >30,000hours
With Balancer, Short circuit protection Overcharge protection Over-discharge protection Overcurrent protection, Remove protection condition automatic recovery, without activation
