I came across this Video titled:

The Lithium Ion battery has destroyed Solar Power as a Hobby!

There were two things that really stuck out for me when the guy was talking about his Lithium batteries versus his old Lead Acid batteries.

First off, the guy appears to have some real world experience operating his Off-Grid home using Solar Power with both Lead Acid and Lithium batteries.

The two things that really caught my attention were:

1) his Solar System is much more efficient with the Lithium batteries installed (he mentions saving 2 Kwh per day with Lithium).

2) there is nothing to maintain with the Lithium batteries, with the Lead Acid batteries there was always something that needed attention (watering, checking on their condition, de-sulfination).

I have to agree with his assessment, once your Lithium batteries are installed, there is really nothing to do but simply enjoy having a very reliable source of electric energy.
