in order to do Lipo you have to have a charger that is compatible with Lipo (preferably balance charger) or an external balancer, lik an Astro Blinky. You will also need to have a low voltage cutoff so you don't damage the battery. Then there's the whole C rating thing.
That works out like this C is the capacity of the battery. So say you have a 5,000 mah (=5Amp Hour) and its 20C that means your maximum discharge rate is 20 times the capacity or 100 amps.
they will have a maximum charge rate usually 1-2 C so 5 or 10 amps. So you can charge in 1 hour 1C or 30 minutes 2C or so.
And stay away from MaxAmps.
