Just had an idea about battery metering...
One of the indications of the battery discharging is that the voltage sags under load.
The degree of voltage sag (for a given battery) is dependent both upon the charge state of the battery, and the load it is under.
So would a battery meter that measured both the voltage and the current and then compared against a notional "table" of charge statuses produce better results than the common "just measure the voltage" type of meters?? (Maybe it could be made more useful by either recording a rolling average or a peak "sample and hold" type arrangement)
Discuss.
Cheers
