dont buy that charger.
It will not charge any NIMH batts (3300s) properly. It was made only for Nicds.Novak's newer Ionic and their Millenium are their chargers that charge NIMHs.
If I were you, I would just go ahead and buy a top charger, such as a Turbo 35, one that discharges, cycles, charges, gives numbers, etc. I wish someone had given me that advise when I was looking for a charger, because a turbo 35 ended up being my charger after ditching 3 other ones...
Super Brain, Duratrax Intellipeak, Integy 16X5, then I finally bought the Turbo 35, and now I am happy, because I know the confirmed numbers on all my batteries, and I can compare them to the cell numbers with a 30 amp discharge. I know which pack to run in the main. Right now, I would not settle for anything less than a turbo 35, because that is what the industry standard is for matching cells (with the turbomatcher by the same company). With a top charger, you always know you can stay competitive. Though some of the lesser chargers will still do fine, I would just go ahead and buy the best, especially in 4-cell racing. Every hundredth of a volt counts!
