2 series 8.4V18650 lithium battery protection board Type-C charging port power tools high current energy storage circuit

Working principle and role, when your battery voltage has a section of polymer 4.18V (LiFe3.6V), the protection plate on the section of the equalization will automatically open, equalization open after the protection plate on the equalization resistance will start to discharge (equalization open discharge, the protection plate will have a slight heat, this is a normal phenomenon.) This battery is charging and discharging, the other did not reach (polymer 4.18V, LiFe3.6V) is only charging and not discharging, and then when the highest one reaches (polymer 4.25V, LiFe3.75V) when the power will be cut off to protect the other batteries will all stop charging. This working principle can make your battery in charging, balance charging let your battery voltage to achieve the effect of balance, of course, if the battery cell quality is not good or not matched, the voltage gap is large, then the role of equalization function is also minimal.

The size of the battery capacity and the size of the current with this board is not directly related to the capacity is not a large current, mainly to see the continuous current, that is to say, the larger your motor you choose to protect the board continuous current should be larger, with your battery capacity is not directly related to
