1. Balanced output cable is 20AWG silicone cable, and main input cable is 14AWG soft silicone cable (400 cores), which can bear 200℃. 2. The overall voltage is more balanced and the difference of average voltage is smaller after the individual cells have balanced. 3. Compared with 6 times balance of single charge, once balance can shorten the charging time greatly, which has 6 times charging current and only needs 1/6 charging time with 6 battery packs in parallel. 4. Can supply balance charge for 1-6 batteries (containing Lipod, Life and Lion) in parallel and support 3 parallel charging boards for combined use to charge 18pcs batteries with the same nature simultaneously. 5. Can avoid overcharge of single battery to improve the balance efficiency and balance the charging cycle.
