Frequently asked questions
How do I wire the balance leads?
Connect the balance wires in order, starting from B- (negative) at the lowest cell up to B+ at the top cell, then connect the main pack leads.
Is it compatible with any number of cells?
Use it only with six Li-ion cells in series (6S). The 22.2 V rating corresponds to 6 x 3.7 V cells.
