Upgraded My Batteries to Lithium - Woo Hoo!

I never know if I am doing the right thing. Sometimes I think I am over charging the batteries but isn't the converter/charger supposed to rationalize the power to the battery and only trickle charge as needed?

So then I go an unplug it and disconnect the batteries for a while, then plug it back in.

I have wasted a few RV batteries in my day albeit before the Airstream. So I can't trust myself with $3000 in batteries. My grandfather was an electrical engineer and I certainly didn't make him proud.

The lithiums actually have a storage procedure. And will store without the problems that Lead Acid have.

Changing out the stock Airstream charger is the first upgrade that anyone who is interested in their batteries and off grid electrical use should do. Left plugged in all the time will destroy your batteries fairly quickly. I know that some people report having no issues with the stock Airstream charger and leaving their trailer plugged in all the time, but in my opinion either they are cycling the "store/use" switch to prevent these issues or they just wouldn't recognize a good battery if it hit them in the face.
