Continuous discharge current (upper limit): 20A (If the cooling environment is not good, reduce the load current use)
Balanced version: Suitable for starting currents below 25A and below 50W power drills, or resistive loads below 168W, with balanced charging function.
Applicable scope: Suitable for lithium batteries with nominal voltage of 3.7V and full voltage of 4.2V (including 18650, 26650, polymer lithium batteries, without limitation on the dimensions)
Standard Edition: Suitable for starting drills with currents up to 25A below 50W, or resistive loads below 168W
Note 1: The successful start of power drill requires two 10C-20C power batteries, or four 5C-10C power batteries (ordinary 18650 can not start drill! ! !); 0V and 8.4V cable, use 2 square mm Above copper wire (cannot use nickel plate!!!)
Note 2: Connect 0V, 4.2V, 8.4V according to the diagram strictly. When connecting the battery for the first time, it needs to be charged before output.
Note 3: When the battery is charged, 430 resistance heating is a normal phenomenon, indicating that the equalizing circuit is working; if the 430 resistance is also heating in the state of not charging, please check whether the wrong line is connected.
Do not mix good batteries and bad batteries together! The capacity/internal resistance of 2 batteries should be as close as possible! (1 good battery + 1 bad battery = 2 battery use effect).
