    Trek full suspension with BBS02

    Hi all, I bought a BBBS02 to install on my old Trek VRX 400 after reading about them here. I previously had a 9C hub and Lyen controller on it, but the 9C seized due to water ingress. The 9C wasn't suited for crawling up steep hills anyway, which is what I hope to do now. Parts arrived...

    New toys!

    No purpose to this thread other than to say that my 9c motor, Lyen controller and other bits and pieces came through the post so I spent the evening joining the wires together and to my bench power supply (no batteries yet) and spinning the motor up.. What a cool noise :D Flat out on 60V...

    Ebay A123s

    There are several vendors with what claim to be A123 18650 cells at reasonable prices. Is anyone using these, as opposed to tool packs? Such packs are *not* available cheaply in the UK. Are they genuine? Are there any preferred vendors, or those to avoid? Thanks a lot. (PS I know there's...

    Mystery motor

    What is this? It has a sticker saying "408" on top. It looks like a scooter hub motor, has 3 wires sticking out. Shorting any two of them makes it difficult to turn. Something I can use? Weighs like 6kg!

    pop bottle shrink wrap

    I read this idea here somewhere but couldn't find the thread. Anyway with the BMS I just got from alswiseowl I wanted to try that, and here it is: 2L lemonade bottle, heatgun, job done! In fact I will do it again after tidying up the wiring and maybe trap the BMS in it as well. But it...

    Prismatic cell pack problem

    Hi guys, I'm having a problem with the first LiFePo4 pack I bought, 3 years ago. It is 24V, 10AH and has actual prismatic cells rather than groups of the little cylindrical ones. I thought this was a better approach and the pack is very nicely built. I used it to replace the 2 SLAs on my...

    BMS - where to buy - for pack build?

    Hi Endless Sphere people, I'm new here. I bought a 36V chinese "ping-like" duct tape LiFePo4 pack last year, 12S 10P, and cut it down to 5P. It's working very well on a hybrid bike, with a Heinzmann motor and drive (9 or 10A max). Now I want to use the remaining cells to make another pack for...
