Todays ride was eventful. I got something stuck in my front brake caliper going down a steep rutted lane - hairy - had to rely mostly on the back brake. New pads should sort it.
The other issue was that my controller went into limp mode because of overheating. It has done this a couple of times before on steep climbs, but only in the height of summer. So this was a bit of a surprise. Was climbing a long haul of varying incline, in total it's about 2.5 miles. I was about 3/4 of the way up, where the gradient kicks up for about 200yds, when the controller wimped out. It was too hot to touch for more than a second or two. Done this climb loads before, never had this happen. Must admit that I think my legs are suffering winter layof blues 'cos I'd got down to 6mph and couldn't maintain my usual 8mph. Stopped for a drink and continued after a few minutes with no further issues. Strange for tis time of year though.
Anyway I thought it might be time to think about fitting a heatsink - but I have no idea where to start.
My controller has a die cast case and is bolted to the underside front of the rear battery rack. The underside of the controller is cast rippled making it difficult to fit anything there. I thought about a plate fitted between the case and rack, extended out sideways and to the front, but I'm not sure a flat plate would give enough surface area.
Anyone got any idea's?
Thanks.
