If you are just using a wall adapter plug like charger, the Triton would definitely be an upgrade from that. I was looking at it, but went with the AstroFlight 109 instead. I only needed/wanted to have a new charger for LiPo's only, and didn't mind spending the $$ to save packs, and I believe that the Triton did everything form NiCd's-LiPo's including NiMh's.

Charge rate - from what I understand 1C = 1 unit of current capacity (so to speak), a 1C charge rate = mah of battery pack / 1000ma (to get to amps) x 1C = amps for charge rate.

So a 2100mah pack divided by 1000ma = 2.1amps times 1C rating = 2.1amps = charge rate at 1C -- Just as an example a 2C charge rate would be 2100ma/1000ma = 2.1amps x 2C = 4.2amps

It is more of a recommended charge rate deal than a what battery can handle issue.

When you look at what a pack can handle as far as output, for example a 2100mah pack that is rated at 15C - 2100/1000 = 2.1amp x 15C = 31.5amps

Hopefully this helps in understanding it some. I had to go through the numbers a lot fot it to make sense to me.
