We are upgrading to a Lithium battery and a charger/converter that will accommodate same. We are getting a 12 V 100 ah+ battery. My only problem is that it appears they all might be made in the same Chinese factory, but have different names. So, I have to look closely. I can not afford those made in U.S.A. as they are out of my reach. I hope to get either 1 or 2 100 ah and put them in parallel.
If anyone has purchased a Li LiFePO4 battery in the last year and likes it, please let me know the brand and if you have it the warranty contact information.
By the way, the battery I have now is a Diehard Gel, deep cycle.
