Re: A Battery Warning query

But the issue is it appears that Lithium batteries deliver a higher voltage under load, and therefore have the potential to deliver more current.

The camera will use a regulator(s) to supply the various circuits inside it with power. If it is a simple linear reg. then it will run warmer with a higher battery voltage because it has to drop more volts, the current is unaltered although it is taking higher power from the battery. If it is a switching reg. then for higher a battery voltage the input current will reduce thus maintaining a consistent power dissipation in the reg. and power consumption from the battery. Since switching regs are much more efficient and can operate where the input is less than the required output (or both +ve & -ve lines are required) they are preferentially used.
