I purchased an old E-Moto ebike that was missing the battery.
I replaced the controller with a 36V controller and bought a 36v bottle battery off ebay.
The original controller ran at 24V, but I am over volting it.
Here's the problem:
After trying to climb a steep hill (Full throttle and pedaling as hard as I can), the motor just stops giving me any power.
Sometimes it will come back right away if I release the throttle and re-engage it. Other times, it will only give me a 1-2 second spurt before dying again. These issues continue even once I'm on level ground.
If I let the bike sit for a while, it will usually be fine again.
I know I am putting too much strain on the motor. My plan is to ride it until the motor dies, then replace the motor.
What is causing my issue?
1. Battery. I have an LED display that stays lit throughout all of this. In fact, the LEDs jump up to indicate a full battery as soon as the motor cuts out. (This is typical of the cheap display. When under load, it has 2 LEDs. At rest, all 4 light up.)
2. Controller. I don't have fuses anywhere yet and could be hitting a thermal cutoff. The display is driven by the controller, though, which never turns off.
3. Motor. Is over-volting a decade old motor on a steep hill just too much for it?
