I have a weird charging issue,
I have the Zivian Charger, 2001 E825 2 seater GEM car.
I have 6 - AGM batteries.
The charge reader seems all over the map.
I will charge it for a day - it might read 100%, might read 30%.
I will drive a little, turn it off - it bounces to 20%.
I will then charge for a few minutes - it jumps to 80%.
The charge reader does not seem to keep an accurate account of the battery charge.
