    charging help for a 2s battery?

    i just got a 'pede 4x4 with the 8hr charger and i wanted to know how fast i can charge a 2s lipo battery.

    my main charger is a ac6 and it charges at 5amps and the battery i want to get says its max charge rate is 10c... what does that mean?? also the battery is a 5800mah

    in that case 1c=5800mah?

    also how long would it take to charge a 5800mah battery at 5amps?

    thanks

    A 10c rate would be 58amps on a 5800mah battery. It will take over an hour at 5amps to charge a 5800mah pack.
    My tranny case is stock :D

    Ok so the C rating 1c 2c 5c is the charge rating. A 2s 4000mah lipo with a 1C charge rate can be charged safely at 4 amps. a 5000mah 5 amps a 6000mah at 6 amps and so on.. Someone please correct me if im wrong but a 2c you can essentially double the charging amps... a 4000mah 2s with 2C charge rate could be charged at 8amps 5000mah 2s @2c 10amps and so on.. Being a 10C charge rate i doubt you have a charger that could put out that kind of current...

    The top chargers right now can push about 40amps so their is no way to charge a 5800mah pack at 10c right now, unless you have built your own monster charger.

    charging help for a 2s battery?

    I believe the iCharger 4010DUO could with both channels in parallel. The rating in that case is 70 Amps.
    Something to remember is that doubling the charge rate does NOT halve the charge time due to the CC/CV charge algorithm. 2C charging should be 1.7X faster than 1C charging. Even faster rates yield a diminishing rate of return.

    See the top of page here:

    I forgot the 4010i could be run in parallel.

    My venom 5 amp charger takes about 45 mins to charge my 2s 5000mah lipo. So a little longer for yours.
    My Black & Blue Rally is faster than your color...
