It is best to charge lipo's at 1C, so you would charge that 4500mah pack at 4.5 amps. Or the 5000mah pack on 5.0amps. If your charger can charge the packs at full power, then it should take roughly an hour, or hour 15 minutes.
I also find that weird that the higher ma pack is lighter... Could it possibly be because of the taps used (or are they the same?) Or the connectors maybe?
I have one of the 4500 packs in 5s. They are 30C packs so they tend to be heavier than the 25c. Also it has ridiculously heavy 8 gauge wire in it. I posted pictures on a thread about it when I got it cuz I laughed so hard at how fat the wires were.
Here is the thread. So far the seem to be good cells. I only have 4-5 cycles on them so far though.
I can't decide if its more fun
to make it...
or break it...
