Jiali intelligent control

　　The principle of the protection board is that as long as one section reaches (polymer 4.18V, iron-lithium 3.6V), this section starts to discharge. Keep charging, and then the highest section reaches (polymer 4.25V, iron-lithium 3.75V), it will protect all and cannot be charged. The battery packs connected in series are charged and discharged at the same time. This is your battery consistency problem, and the protection board is working normally.

　　The protection board, as the name suggests, "is protection", the protection board is to protect the battery, it has equalization function, but the equalization ability is limited, if your battery pack is not well matched according to the wiring instructions, just charge and discharge the protection board a few times. In order to achieve a very ideal balancing effect, balancing is mainly to prolong the battery life and make the consistency of the battery better, but the consistency of the battery cannot be determined by the balancing function, but depends on the battery difference of PACK.
