Throttle assembly for Thumpstar & XRT Lil Mo, Sport 16, and Pro 16 Models & Orion 12, 16, 20 models. This throttle will work with any voltage battery, however the battery indicator will only work correctly with the proper voltage battery. Example: 24v battery with a 36v throttle will work but will always read empty. a 36v throttle on a 48v battery will always read full.
