    Reviving a strange old "KLD" scooter battery

    So I was contacted by a fellow EV guy who has a strange scooter from the early 2010s which has stopped working. The scooter was created by a defunct company called "KLD". The story I was told was: during it's short life the company rewarded the first 100 investors of $100k or more with electric...

    Long board build for work?

    1-2 hours at a walking speed of 3-4 mph = max 8 miles of range. With a buffer maybe ~10 miles of range. Is there a reason you want to make it yourself? There are many off-the-shelf electric longboards which meet that criteria for a few hundred dollars.

I've got a bluetooth dongle also, but I can't find any information as to which app I can use. I've emailed them several times with no response. Does anyone...

    This allows you to run the stock 520 chain and rear sprocket on your electric motorcycle conversion, instead of having to convert the drivetrain to a 420/428 chain. I've got a few of these left from a batch I had made. I searched the internet forever before I had these produced, they just don't...

    Battery box plug / connectors?

The only thing that needs to exit the box is the two 1/0 power cables. Design goals are easy to disconnect and...

    'on board' 1.5kW charger. Which alibaba supplier?

    So many sellers on Alibaba sell these aluminum-housing, waterproof chargers. All appear identical, specs weight and photos. Prices range from $140 to $240 + shipping. Anybody have any experience with these, or better yet a particular vendor? Looking for a reasonably priced 15-20a charger for a...

    Tomos Sprint conversion

    Lurked here a while. I'm selling this project so I thought I'd share it before it's gone. Link here: https://endless-sphere.com/forums/viewtopic.php?f=9&t=110600 Edit: Sold to a new home. Somebody is using it as a hunting rig, which wasn't my design intention, but it's actually pretty good at...
