5S 30A 16v

Application: Nominal voltage of 3.2V, 3.7V lithium battery (including 18650.26650, polymer lithium battery).
Continuous discharge current (upper limit): 25A (if the cooling environment is not good, please reduce the load current use).
Continuous charge current (upper limit): 20A;Suitable for the drills with starting current below 60A, power 100W below.
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 deliberay short circuit.
Note 3: When the load of the motor brush is used, try to connect to the 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 separay 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 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).
Charging voltage: 12.6V - 16V

18V 21V Li-ion Lithium Battery BMS 5S 30A With NTC Battery Pack Balance Charger Cell Protection Circuit Board

Wiring precautions:
1. Installing the protective board requires a certain amount of technical electronic knowledge.
2. When wiring, first connect the B- wire at the soldering pad position to the total negative terminal of the battery (the B- wire should be soldered to a short and thick wire) and solder the wired terminal to the battery pack first, and then insert the protective plate.
3. The connection between the battery terminal B- and the protection board terminal B- should be short and thick, otherwise it will cause the protection board to charge and discharge in advance and malfunction.

4. You need to use thick wires when wiring P+/P-. Wires that are too thin and too long will burn the board!
