    Charge rate for Lipo Batteries Venom 50c 5000MAH and Venom 20c 4000MAH hard packs

    The 5000MAH states to charge at 1C (5.0A) which takes me about 90 minutes to charge. The 4000MAH I charge at 1C (4.0A) which takes an equally long time to charge. Can I charge these safely at a higher rate?

    I like the batteries, especially the 5000MAH but the charge time is forever.

    I charge with a Dynamite Vision Ultra

    Ask the battery manufacturer for max charge rates, 2c is common these days

    You will need a better charger to charge at higher rates

    To charge a 2s 5000mah sized pack at 2c (10 amps) requires a charger with at least 84 watts output

    My charger can charge at 7.0A which would be almost twice the rate I am charging the 4000MAH's at now. Will venom batteries handle this level of charging?
    What is a good charger with reasonable pricing that can charge faster?

    "Ask the battery manufacturer for max charge rates" because this is considered Support and Traxxas does not allow Support of third-party products on their forums.
