Hello, Ammodave.

Here's a link to a discussion thread on Endless-sphere with regards to sensored vs sensorless: http://endless-sphere.com/forums/vie...hp?f=3&t=15491

I've never personally heard of Aotema motors so you may want to use the search feature on this forum or Google to get some reviews.

There are several forum members, myself included who are using the 48v 1000w Papamotor setup with a Ping 48v 15Ah battery with great results.
