Any idea if I had a solar panel for charging would I need some sort of controller to charge these LifePO4 batteries?

If your old "Sealed Lead Acid" (SLA) needs replacing, here is an opportunity to get a 12 Volt 9 Amp hour LiFePO4 battery. I have been using these for several years and would never go back to SLA's.

Lots of RAS threads on LiFePO4 if you need more convincing.

These are a direct drop in replacement to your old 12V 7A battery but weigh only 2.6 pounds. Here's the link.

Craggy Aero also offers the same discount.
