The 14 battery ezgo txt read 58.8v fully charged. The lithium charger goes into constant voltage mode at that peak voltage (58.8v) as I spec'd out with QC (on-board charger) and it shuts off when current drops to less then 1 amp.

The Alltrax controllers can accept up to 60v so this is about the limit.

The 14 battery pack (120Ah) weighs ~120 lbs compared to a pack of 6 T-875's (378 lbs) or 8 T-105's (496 lbs). I also have much less voltage sag with these lithiums then with FLA so performance is many times improved from weight loss and higher steady battery voltage.

The ezgo txt above had a long travel suspension, 25" tires and managed 42 miles on a charge. I built it to keep but did end up selling to build me this 2010 yamaha drive. The yamaha is lighter stock then a txt. I will keep less then 20" tires on it and expect to break 50 mile range with a 14 battery pack.
