    50 amp BBS-HD at Luna

    Dear Gents - thank you very much for the input - much appreciated. The reason I´m even getting into this - is that I mainly use my mountain bike for singletrack - with a throttle only cabling solution. A small power increase would make this setup perfect. I have my battery in my backpack so...

    50 amp BBS-HD at Luna

    Anyone have a spare wrecked BBS-HD controller ? I am in contact with a German specialist that will assist with making a new controller that can handle 50 Amp - semilar to what Luna has done. Need to send him the original controller in order for him to get an impression of how much space is...

    50 amp BBS-HD at Luna

    I think the way to move forward is to develop our own controller. I cannot be that hard... I can make a 3D model of a casing semilar to the original controller cover on the BBS-HD, with the exact same mating face against the motor. After that we send the STEP (3D) file to a number of...

    50 amp BBS-HD at Luna

    Tuning the BBS-HD ??

    That´s exactly the point of this thread ,0) What are the limitations for exceeding the 30 Amp ? There must be a reason that Luna Cycle use an external controller to run 50Amps on the Bafang BBS-HD here: https://www.electricbike.com/project-x-building-the-baddest-and-fastest-3000w-bbshd-ebike-ever/

    Tuning the BBS-HD ??

    Thanks for the replies... 65 amp is NOT what I want - as this has already been tested with bad results. What I want to know is whether the current limit can be increased further than the 30 amp - to a level around 40 or 45. Luna Cycles is currently testing the Bafang with 50 amp on an...

    Tuning the BBS-HD ??

    Kill switch on main battery power supply ?? Options ?

    Thanks for the replies ! I think I might just hard wire the on/off wires from the controller and add a keyed contacter in my battery box - for cutting the battery supply - as i don't need an additional switch on the handlebar in that case. But let's say I'd use the type that are used for...
