    A look inside a Juiced 52V 13Ah battery.

    There have been a few photos in the past of the Juiced battery as people had to open them to fix the connector, this look might go a bit farther. I bought a defective battery just for the case, but turned out the case is too small to fit my replacement pack once all nicely protected. While I...

    Electric bicycle battery repair/diy

    Hello there! I recently purchased an e-bike (Batavus Padova Easy) with semi dead BMS, semi it's because it allowed the batteries to be charged fully, and that's good because it allowed me to test them, and once I did, I noticed that the batteries are OK, they hold charge decently, not dropping...

    Hi folks, I am starting an e-bike sharing project for a town in France. We certainly need to track the GPS coordinates of the bikes. There are multiple devices for that. However, I haven't found any market ready solution that also reads from the bike system its battery level and its mileage...
