ps not sure if the open source will work as it is a bbs01
It won't, luckily I've haven't read reports of 36V BBS01B controllers being locked. Before removing the throttle from my bike, I did consider mucking about with Penoff's config tool, written in Delphi, but attempting limiting the throttle to 6km/h wasn't worth buying the latest version of Delphi, and possibly a new BBS01B controller if it got bricked in the process. That being said, I've remembered I have spare controller, which I blackmailed from my BBS01b seller with threats of thousands of bad Amazon reviews because he'd lied to me during pre-sale enquiries about having "Multiple diagnostic facilities throughout Europe", and I'd had to pay to post my dead controller to China for a "free" replacement - it wasn't free! I had to post it for £20!
While it was being "Tested" for weeks in China using some unknown and imaginary firmware "Diagnostic tool" and awaiting him sending a new one for "Free" under warranty
, I bought another controller from Greenbikekit after you posted a link and recommendation - thanks again for that. It's still working great, and at the recently increased current limit of 18A. I'd increase the limit to 20A, but I need 2A for the lights soldered to the bike battery, and it's BMS is limited to 22A continuous. On the bright side maybe I've dodged a bullet, perhaps 20 X 36 = 720W would cause my 20" wheeled Dahon Helios frame to permanently fold and snap? No sign of that at 648W - not yet anyway, touch aluminium. Fortunately I don't need 720W, even with 52T... 540W and 52T was ok dragging a 90kg+ bicycle trailer up steep hills. If I were still young and foolish, I'd get a 56T or 58T chainwheel, as I'm sure there'd be enough torque on 20" wheels at 20A. Particularly now I've lost over 3.5 stones.
