I've used Novak, Competition Electronics, MRC, Hyperion, Thunder Power, Revolektrix. The BC168 balance charger charges 1 to 6S at up to 8 amps through the balance tabs only. It also discharges and is super adjustable. It's like six separate and precise 1S chargers in one package that will charge your packs in a hurry at cell level. So there's no bleeding off of voltage on the cells that charged faster while the others are catching up during a balance mode that can take hours and WILL damage your batteries. This thing charges real quick and does not damage the cells. Find them on ebay at under $80 each and try to find free shipping. Comes with a parallel harness and a temp probe.
