charger help - what charge rate

[simplechamp]

At 1C a pack should take about an hour to charge. So what that implies is that the said Hyperion pack can be charged at 5C (12 minutes, 1/5 of an hour). For that 5000mah pack a 5C charge rate is 25A. Any lipo pack should be clearly labelled with it's max charge rate.

To calculate charge rate you take pack capacity (in mah), divide by 1000 (to convert to Ah), and multiply by charge C-rate (1C, 2C, 5C, whatever value you want to charge at)

3000mah pack charged at 2C would be: 3000/1000 = 3, then 3 x 2 = 6, so 6A
