“Powerful” hints
A couple things I am currently doing to help keep my battery use low;
– Buy a set of clip on LED lights and use them instead of interior trailer lights
– Buy a rechargeable LED flashlight and use it instead of interior trailer lights
– Use the laptop battery while working. Use it, power it off, then recharge it as you drive down the highway using your engine-battery and a small inverter. Use caution here and unplug it every time you stop. You do not want a dead engine battery!
– Avoid foods that require refrigeration. Find; Canned meats instead of fresh or packaged, mustard and catchup packets over jars, dry milk instead of fresh.
– Get you solar panels facing the proper direction (South). 30 watts of my solar panels are mounted on top of the van facing straight up. The sun does not get to them until 10-11 am and stops hitting it by 3-4 pm. These are great for those days sitting in a Walmart parking lot as I’m still getting some charge even when I can’t whip out all my panels. However, I have left all my other panels unmounted so I can face them directly into the sun when I use them.
