3S 4S 5S 6S 7S 15A BMS Lithium Ion LiPo Battery Pack Balanced Equalisation Board

This protection board is for Lithium Polymer and Lithium Ion batteries only, it cannot be used for Lithium Iron Phosphate batteries.

Please ensure that the batteries are identical, preferably from the same batch and have the same state of charge.

Stable performance, support disconnection protection, over-current protection, over discharge protection, overcharge protection, with balanced charging and discharging.

Even when building a battery pack with identical and well matched cells, the individual state-of-charge of a long string of cells will diverge over time and charge cycling. This is due to small variations in cell characteristics and localized operating conditions, which can lead to small differences in self-discharge and load current.

Equalising or balancing a multi-cell pack helps to maximize capacity and service life of the pack by working to maintain equivalent state-of-charge of every cell, to the degree possible given their different capacities, over the widest possible range. Equalising is only necessary for packs that contain more than one cell in series. Parallel cells will naturally equalise since they are directly connected to each other, but groups of parallel wired cells, wired in series ( parallel-series wiring ) must be equalised between cell groups.
