Ok, I hooked up a need battery voltage/current and energy meter in my trailer last night. Had lots of fun turning things on and off to see the effect. It also allows me to set high and low voltage limits and alarms. We plan on doing a lot of boondocking and I am curious as to how well the battery power will hold up. The meter shows a cumulative Wh value and allows me to reset it. Long term, I'd like to add a solar panel controller to allow me to make up what I have used if the sun cooperates.
I have replaced all of the lights in my 21 ft TT with LEDs. And I think that that water pump and furnace blower are the only other 12 volt consumers (for now, will add an inverter to get some 120 volt outlets later). So my questions are:
What is the typical Wh's that I can get out of my battery? I am sure it depends on the battery type and load-over-time profile. Are there battery capacity specs on the battery label that should indicate what to expect?
What about voltage? Of course lights will get dim, and fans/pumps run slow, but is there a voltage "limit" that most use, perhaps from over-depleting the battery? I set my monitor to alarm at 9.5 volts, just seemed like a good number to me.
TIA,
JH
