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

Wire Diagram
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!
