Well it sounds like you've got the matter well in hand
Apologies if my previous post may have come across in any way condescending. The price of controllers these days is pretty low, so worse case you couldfind a replacement that's more up to the job in hand.
Best of luck
No not at all, I was only too glad to have your input and the other posters have all put valid points across
The unit is far too hot to touch, after a long journey. This is November, I could see potential problems in the warmer months.
I did wonder about temperature dropping performance. The temperature co-efficients for the components and resistors will all cause a different current, depending on temperature.
When I'm on the pedal assist the power display power drops rapidly from 4 LED's to 1 or 2 LED's,(rarely use throttle). When I coast/freewheel the power shoots up to 4 again.
On very steep hills and low battery the power drops to overload.
I would interested to hear from other powacycle users if their display does a similar 'equaliser display' when on and off the power.
There are some figures on the unit, all writing is in chinese but there is a 120 degree written within the text.
I haven't opened up the unit but suspect that the types of resistors used will vary between units, hence Daniel Wecks ambient 40 deg and my scorching 70+
Bottom line is, as you have all stated above mounting the unit to get max cooling. Plenty of places, but I'll fabricate an alum box mounted on the panier rack.
In todays ethic of energy saving I thought about some 8mm copper pipe coiled round would make a nice cuppa at the 10 mile point don't ya think
