Microwave off Inverter. Volt drop with 3 batts parallel

Here's a vid of more of my set up. Running micro off inverter to see a better idea of volt drop with 3 batts parallel.

I dont make exciting vids but it shows more or less how I boondock..

I know this vid may not show anything at all as I only had the micro running a few minutes.. Probably a waste of youtube time... lolol


1. Rule one. Waste of time running the Micro off inverter. especially a modsine type. I just dont have enough invert power . You need puresine at least.

To me its a popcorn maker and coffee warmer.

And again as I discussed elsewhere I dont need to use the coffee pot or the toaster oven as I have a perculator and an RV oven.

But I am torn between keeping 12's or going 6 volt.

If I went 6 volt I will probably do away with the truck battery, as it will not be needed.

Plus I dont know the effects of ampdraw from the RV batts down the wire of 7 pin 20 ft of maybe #8 wire.

    The other way around - as I recall the OP has 2 G24 trailer batteries and a third G24 sitting in the engine compartment of his truck ... truck starting battery isn't involved in this. That G24 under the hood he has wired through a 7-pin Bargman - a poor solution when using heavy gauge booster cables would result in far less voltage drop.

    Horrible. :M Forget the Bargman cable and use heavy gauge booster cables, the heavier and shorter the better. I'd prefer to use at least 2 gauge but any sold around here are too long and too expensive so recently bought a 16' 4 gauge set but may cut it even shorter to reduce voltage drop even further when I load support my trailer battery with my truck.
