April 21, 20215 yr Author Many 24v controllers will run with a 36v battery, but there are pitfalls. Most importantly, the controller won't cut off the power when the battery reaches 31v because it's programmed to cut off at 21v for a 24v one. That can brick your 36v battery if you're not careful. also, any indicators you have for yor battery charge level will show that it's full all the time, which adds to the chance of you running the battery too low. batteries should cut off by themselves when they go too low, but that system is not 100% guaranteed. several batteries that I tested didn't cut off at all even theough they were supposed to. Yeah, I'll hang fire trying anything until I've got the lot and can install in one go, I have a limited attention span (especially if anything goes wrong) , so best done in one go! Cheers Ian
April 27, 20215 yr Author The FedEx man came bearing gifts this afternoon. Jools and I set to and fitted the new battery rack, controller and display, took our time in an effort not to mess up. Getting the new display cable through the tube was a pain and eventually accepted that we were not able to get it to go up the seat stem tube, well hugely surprisingly it worked straight off. Plugged the battery in and powered up the display, check! I'd fitted a simple throttle (thanks for the advice VFR400) and it powered the front wheel, check. Disconnected the throttle and went for muscle power, wow, check. The brakes don't cut the power immediately, but I've figured that one out, I need to splice the two connector from each brake into a single connector, job for tonight, finally the lights don't want to operate, far from a deal breaker. Nipped it outside and gave it a maiden run down and back up the lane to the side of the barn, seems very good, Jools did the same and proclaimed it 'better than before', damned by faint praise! We tidied things up and I decided to give it a go on the road to the next village, up the hill for half mile of constant easy(ish) gradient, it climbs 50m according to Google. I ran out of gear going up it! This amended bike might just be a bit quicker than I anticipated! Sort out the brakes tonight and we'll give it a proper test tomorrow, weather gods willing. My biggest worry is that I'll not be able to keep up now, and no she's not getting the throttle! Thank you all for you assistance and advice, looks like I've saved myself the best part of a grand. More later. Cheers Ian
