you can choose the amp rating for charging. 1c would be 5 amps for a 5000mah pack. the 3s pack will only charge at about 4.4 amps because of the charger's watt rating, but it will still charge up pretty quick.

for example, i like to charge my lipos at 4amps and my ni-mh batteries at 2.5amps. the amp rate on the charger goes by .1amp increments.

make sure you plug in both plugs on the battery into the charger. also make sure you choose the lipo balance setting or the fast charge setting. in the fast charge setting, it will charge at the same rate, but it will save about 15-20mins by not trying to squeeze those last few hundred mah into the pack. i always use the balance mode as it only takes about 50-60mins for a charge for me, or about 70mins if i drain the pack down to the low voltage cutoff.

if your esc doesn't have a low voltage cutoff build in, i recommend you get one.
