How to maintain the battery in E-PTO

The most important part of the battery’s maintenance is balancing the battery. Battery balancing is a technique that improves the available capacity of a battery pack with multiple cells and increases each cell’s lifetime.

Every second week the battery should be fully charged and left alone for a day or so. It assures that every single cell has full capacity. Why is it important? Because the cell with the lowest capacity determines the total battery capacity.
