Balance charging and protecting 4s LiPO battery pack
A Protection Circuit Module (PCM) is designed to provide ''last-ditch'' protection which (hopefully) prevents damage if other circuitry fails. It is not supposed to be used as a substitute for a proper Lipo charger, or to turn the device off when the battery gets low.. Balancing modules are designed to equalize small capacity differences between cells, to ensure that they
