3 Strings 12V Volume 18650 Lithium battery control protective board 25A30A40A60A same mouth separation band balancing charging

Scope of application: Lithium battery suitable for nominal voltage 3.7V and full voltage 4.2V (including 18650, 26650, polymer lithium battery, no limitation of shape size)

Product size: 41*55*3.4mm (enhancement version)

Product weight: 8.8G (enhanced version)

Charging voltage: 12.6V -13.6V

Continuous discharge current (upper limit): 40A (if the cooling environment is not good, please reduce the use of load current)

Continuous charge current (upper limit): 20A

Enhanced version: Applicable to electric diamonds with a power of less than 80A and less than 130W.

Note 1: It takes 3 15C-20C power batteries to successfully start the electric diamond, or 6 10C-15C power batteries (ordinary 18650 cannot start electric drills!);The above copper wire (Nickel tablets cannot be used!!!!).

Precautions 2: Strictly follow the figure 0V, 4.2V, 8.4V, 12.6V, don't deliberately short circuit.

Note 3: When charging the battery, the "430" resistance fever is normal, indicating that the balanced circuit is working; if the "430" resistance is also heated in a state of non -charging, please check whether the wrong wire is connected.

For some customers with poor electronic foundations: Do not use good batteries and different batteries together! The capacity/internal resistance of the 3 sets of batteries, the better!= The use of 3 difference batteries).
