Hanbaili Battery Protection Charger Module High Precision Battery Module with 12.6V 40A 3S Li-Ion Voltage Tester

Description

✅Hanbaili-Strictly follow the diagram to connect 0V, 4.2V, 8.4V, 12.6V, do not intentionally short circuit. ✅Hanbaili-Hanbaili Battery Protection Charger Module High Precision Battery Module with 12.6V 40A 3S Li-Ion Voltage Tester ✅Hanbaili-Successfully starting the drill requires three 15C-20C power batteries, or six 10C-15C power batteries (ordinary 18650 can't start the drill! ! !). ✅Hanbaili-When connecting 3 sets of batteries in series, please make sure that the voltage of each set of batteries is the same. If not, please fill each set of batteries separately and use them in series. . . In the discharge test, the battery with the faster voltage drop is the bad battery. ✅Hanbaili-For some customers with poor electronic foundation, please explain: Balance charge is auxiliary function, try not to mix good battery and bad battery together! 3 sets of battery capacity/internal resistance is as close as possible! (2 good batteries + 1 Poor battery use effect = 3 bad battery use effects).
