    Charge Time

    I have a Duratrax Onyx210 Charger and im charging the stock traxxas pack. The lowest setting is 0.8 amps (im ussing) at 45min its only at 550mah is this right? The next setting is 1.5amps should i change it to that next time?

    2 amps is too high for the stock pack. You will seriously reduce it's life.

    550mah sound right for 45 minutes of charge at .8 amps.
    The pack is 1100 mAh, so a full charge at .8 amps (or .73C) would be around 83 minutes.
    I think I read that the back of the pack says you can charge at 1.5amps (I'm not sure, so check the pack), but I wouldn't charge it that high. I wouldn't charge a 2/3A cell (which these packs use) at over 1C (which would be 1.1 amps for this pack).

    Remember, the higher the charge rate you use, the more abusive it is to the battery.

    1amp is an acceptable charge rate for these packs. You might wear the battery out quicker than a lower rate, but you're not going to run the risks you would with 2amps.

    It's a 1200 mAh pack, so 1.2 amps is the "normal" charge rate. In my opinion, they are cheap batteries, so charging them at 1.5 or even 2 amps isn't worth worrying about. The slight reduction in life for the pack probably comes out to like 15 cents. You can get better lipos that fit for under $15 each.
