My Gem e2 gel batteries are finally dying, after many years of faithful service. I have the R4F blue motor but everything else is stock. Used primarily for going around the neighborhood and for golf.

Looking for suggestions for converting to Li ion, with minimum other revisions.

I had a couple of the newer 2016+ Gem that I installed the Litime 51.2v 100ah and was very happy with performance and ease of installation.
