Let's just say you have a 5000mah LiPo pack...if you have any hopes of charging the pack in an hour... you will need a charger that will deliver at least 5 amp charging rate and 37watts of power. I would say if you are planning on just 2S LiPo packs... find a charger with at least 50 watts of power and at least a 5amp maximum charge rate. That would do you just fine...as long as the charger has a "storage mode" function (most do, but some don't).
Watts Needed (37) = Battery Voltage (7.4) x Charging Amps (5)
Watts=Volts x Amps
And someday if you decide to get a 3S 5000mah LiPo (11.1volts) pack, you would need a charger with 55.5 watts of power to charge the pack @ 5amps to achieve an approx. 1 hour charging time.
