4S 100A BMS PCB 12.8V-14.8V Li-ion Lifepo4 4 cell 32700 Batteries Protection Board With Balance Protection 

This HX-4S-F100A based 100A BMS board is also called (a battery management system ). HX-4S-F100A is a protection board for lifepo4 26700/32700 cells. There are 10 MOSFET’S, a strong heat-dissipating aluminum sheet installed on it, and the continuous current limit is 100A. It is suitable for 3 series lithium battery packs such as inverter, xenon lamp, and solar street lamp.

Package Included:

1 x 3S 11.1V High Current 100A 3.7V Lithium Battery Protection Board With Balance

Note:

• The successful start of the drill requires three 15C-20C power battery, six 10C-15C power battery (ordinary 18650 can not start the drill!!).
• strictly according to map wiring 0V, 4.2V, 8.4V, 12.6V, do not deliberately short circuit.
• 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.
• 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. The The Discharge test, the voltage drop faster battery that group is poor battery.
• For some of the poor basis of electronic customers to explain: 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).
