Monitoring Amps
I recommend installing a TriMetric battery monitor model TM 2030. This will show you your real amperage or wattage usage in real time, as well as record usage logs. It will show you amperage remaining, time until charging needed, and many other parameters. It is manufactured by Bogart Engineering, and I am not connected to them in any way.
The monitor takes ALL the guess work out of where you are in terms of voltage use, and voltage remaining.
