I've been trying to establish a range for my cart, figured installing a digital voltage meter would provide me with real time readings for diagnosis. Unfortunately, its opened up more questions than answers. So, here they are:
1. My pack reads 38.7V after its charged, and sits for over 12hrs. Doesn't this seem a little high? (I'm under the assumption it should be 38.3V, fully charged)
2. After about 6 miles of carting around the neighborhood. Stopping, accelerating, cruising at bursts of full speed, with the whole family, it read 37.3V. This was after I let it sit for about an hour after cruising. Doing the math, this means I get 4.3 miles for every volt. And assuming I run it down to the 50% SOC (36.3V), this means I only have a range of approx 10 miles?? Does that seem right?
For the record, they are Trojan batteries (T-105) , with a J13 code stamped on them (Batteries are over 2yrs old). My cart is lifted, with rear seat, upgraded cables, F/R switch, and 500A controller with the "Raptor" motor. And these readings were taken with about 575lbs of cargo (me, the wife, two kids, and the dog).
