Hi Peter,
Glad it all worked out. We've supplied and fitted a few of the UM throttles and I think the max throttle only powered speed (with the white wires disconnected) may be influenced by which version of controller is fitted as we've seen mixed results between around 10.5mph and 17+mph. System voltage doesn't appear to be a factor but there have been a few different versions of controller. Sounds like the more recent controllers behave more consistently giving at or close to 15.5mph.
All the best
Steve
