Thanks for the feedback. I think I will likely go with the 25 amp as suggested here. Not sure what year the electric system is, the conversion was mostly done when I purchased the truck, although not very well.
Those pictures of the exploded battery are scary. What brought this to my attention was when I was putting the battery back in after removal for the winter, I noticed it leaking around the positive post. Thought that was strange so put a battery tester on it. Tester said overcharging so tested with multimeter to confirm. Might have avoided a major issue.
Will wait for new VR to arrive and will post back.
Thanks again for the quick responses.
