How long to charge 4S 5000mah?

Hey guys,

I'm just getting into multicopter flying and recently picked up a couple of lipo 4S 5000mah batteries.

I connected them to the Hyperion EOS0606i charger and have been charging at 6amps for over 1.5 hours so far. Is this normal? How long should it take? Seems a bit excessive?

My 4S 3300 pack takes just over an hour to charge at 5amps. I just want to make sure I'm not doing anything wrong here.

Thanks!

As I recall, the EOS 0606i has a maximum output power of 50 watts. As such, max charge current on 4S packs would be ~3 amps, even if you have it set at greater than 3 amps.

At 3 amps, a 5000mAh pack should take at least 90 minutes, and perhaps longer, depending on balance, internal resistance of cells in pack, and depth of discharge.
