Re: Top speed and acceleration drops dramatically after few miles
42.7v when cruising at top speed??? That sounds ridiculously low to me.
Especially since your fully charged V is good. When I still had lead acid batts they would not hold a full charge and I don't have a float charger so I'd start my trips with 50.1 or 50.3v and when I nail the Go pedal it'd drop to 46.x V then when it got to full speed I'd see the V increasing again and it'd settle in the upper 48.x range. On bad batteries. At the end I had about 1.5 miles of usable range then it started to slow.
I have a 2011 TXT48 with 23" tires and at the time it had stock controller still/motor. Now I have a better controller and lithium batteries.
