Guys,

I'm trying to model a satellite battery life in excel. (lion polymer batteries)

I know how much power i'm getting from solar panels, and I know how much power and current I'm draining on a minute to minute basis.

I have a 3.75 Ah battery and have their Voltage vs. Capacity curve charts and stuff.

Anyone know how to go from Watts to Ah? I'm having trouble applying it to a minute by minute basis

help?
