I'm looking for a simple and reliable 36v 250w sensorless controller for my PRIMA Powerbike and my wives Piaggio Albatros (technically the same).
The original controllers are sadly nothing but trouble, I know electronics and daily repair al kinds of equipment but these are just...italian..
So I'm looking for another alternative, I preferably keep using the original switches (one on/off and one eco/sport),
Batterypack is made from 32 GP 11ah nimh cells, (so after a quik charge cel voltage could easily be 1.5 volts times 32 equals 48 volts so maybe that fried the original controllers
But could use less cells ore only slowcharge..
Motor is 36 volt direct drive no sensors rated 250 watt.
Any ideas on what (not) to buy??
