I've got a 250w 24vc scooter controller and a 24v 6ah Lipo battery I'm using in an older Peg Gaucho. It was stock 12v.
I'm using a 5v throttle and was able to retain the stock high/low/reverse.
Long story short...the thing rips when you drive it for the first time. But after about 5 minutes of continuous use, its starts to slow down...and then after 7-8 minutes its only able to go about half the speed it was when it start.
The battery gauge on the lithium batteries (Batteries have their own BMS) show still 3/4 full...and there is no way they would have lost half their voltage.
I'm thinking that either the controller is overheating (is that even possible?, or would it just quit working if it overheated) or the motors are getting heat soaked.
I've seen some guys run heat sinks for the motors...is this why?
First I thought it was the batteries, but I had a second 24v 10ah battery (totally different brand) that I tried and same results...so it leads me to believe its the motor or the controller.
Need advice so I know how to fix. Thanks!!!
