Hello, does anyone have some handy experience advice of removing spot weld nickle strips from 18650? I've tried a few methods, dremmel the spot, pliers, teeth.. but still seem to manage little holes in the battery surfaces. Thanks, Kerry

Hello, With both these controllers costing $85: 36v 350w 48v 350w Is there any difference in the components of the controller, or is it a bit like the 250w/350w 15A/18A programming change? I would have expected some price difference. I am curious as have some spare (identical) cells I could...

Hello, my (unmodified) BBS01b has done near on 1000 miles, including through recent winter snow and on salty-slushy roads. It's certainly noisier than when I got it, but not in a concerning way (a whurr, no clonking, clicking, grinding or banging). I know it is internally (by UK ebike shop)...

Is there a technical reason that metal framed ebikes don't use the frame as a conductor, like cars do? Seems a logical way of reducing wiring looms.

What happens when an ebike battery goes under a bus wheel So, next question is... what now? Most of the batteries are just dented and the circuit board for the battery conditioner is fortunately fine. Where might I find a pinout for the conditioner? What are the chances that the cells are...

Hello, the display from Bafung (and others it seems) is quite large. I've replaced a small, roughly 5cm diameter speedo which the display was more than adequate for its requirement with the monster which takes up a huge amount of handlebar real estate. For something that gets glimpsed at some...

Hello, i have a 36v battery and wish to run lights from it. Simplicity, I currently have a 6v front nice and bright fella. Is it worth putting in a 36v-6v DC-DC converter, or 'upgrade' and build something with 3 x 12v LEDs in series? If the converter went in parallel with the feed to the rest...
