If you have a 11.1v 3Cell 1800 mAh lipo ( forget the count of the cells and the voltage), the C of the lipo pack is 1800Mah or 1.8 amps.
The C rating of the lipo is a discharge rating that the cell pack can handle, for example a 10C lipo is 10 x 1.8 ( or 1800mAH) which would giva a maximum discharge rate of 18 Amps, also the charge rate for the lipo would be at 1C, so the maximum charge rate would be 1.8 Amps or 1800mAh
Thanks...

As I understand it, the 1800mAh rating gives you the discharge rate of 1800/1000 (hence the "M" ) / HR or a 1.8 Amps per hour discharge rate.

At 18 Amps you would immediately dump all the energy in the battery effectively blowing it, as it would be at it's maximum rate possible.... like shorting the leads?

In the litrature they frequently state that all 11.1v LiPo's are ALWAYS "3C", (my ICE charger manual states this,) while the maximum LiPo charge rate is 1C.

The poster stated he had a 12C battery but I think he means 12 small batteries in a combination of parallel and series to get the right voltage, as some packs do. 12C would be quite massive wouldn't it?
