It is 1C, not one amp. Empty 5000mAh packs= charge at 5 amps, empty 2400= 2,4 amps, etc.


For a nimh the charger keeps the amps constant , for lipo it keeps the voltage the same. So once the desired voltage is reached, the charger then starts decreasing the amps while charging. I hope this makes sense.

It doesn't keep the voltage constant until the voltage reaches 8.4v.

LIPO's charge with the CC-CV method. This is Constant Current - Constant Voltage. The charger will charge a 5000mah lipo at 5amp until the pack is at 8.4v. Then the charger maintains the 8.4v while decreases the amps down to .1 (or somewhere around there).

So, Constant Current (5amps or 1C) is applied to the pack until 8.4v is reached, then the voltage remains Constant until the amps are down to zero (.1).

So with theses hard-case lipos, how do you know if one of the cells has puffed up or not from sitting too long? This is my major concern about making the switch...

With the Orion LiPo packs it's very easy to see if the cells have even puffed a little, the case is sealed and each half of the case is stuck to the cells. So any puffing and you should immediately see the difference.
