    Excellent, sounds like your making progress! So possible internal loose connection. But I still would double check the battery to cradle knife connections to be sure. But hey, a strap never hurts...

    Please look over this terrific thread by Sebz about the cradle connections…

    Glad to help.

    Hi TC
    Thanks for your reply....I went back to the supplier with my problem and his reply....
    ....Its possible the BMS inside the battery is either faulty or the connection has unplugged a little.

    Its worth opening the battery and checking the plug that has 14 series wires going into the BMS, its possible that this has unplugged and also the plug for the battery tester on the side of the battery.

    Which is what you suggest

    My battery does charge to 58.8 volts and after a 50km road ride it drops to around 54.7v. Of course this might vary due to the load that that has been put on it.

    Re the Error Codes...; It showed 04 and 021.
    Many thanks

    Hi Neville,

    From your description it sounds like you might have a battery problem. If the display is shutting down with the issue, and only starting up after a few minutes and a battery power off/on cycle, it might be the battery's BMS tripping. Or loose connections internal to the battery... More particulars of your battery? Does it properly charge to 58.8 volts for a full charge? Does the voltage drop much shortly after charging?Does it sag under load? Double check the battery to cradle knife connections. Make sure they are tight.


    As far as the display, I believe the Luna model can be reset. But not sure if this includes the error codes. Curious, what codes do you have stored?

    DPC-18 Display Documentation.

    I still have an unresolved problem with power shut down, after several months of trouble free running, sometimes when switching the battery and the DPC-18 display on, the system then powers down immediately. Other times it will unexpectedly shut down when riding, then it will take a while to power up again.. I have had an electrician friend who has checked all the connectors for continuity and relevant voltages etc with a multimeter and found everything ok. What we did find is that when the unit has shut down, the test indicator on the side of the battery has ceased to function even though all is still switched on.
    I'm running a BBSHD and 52v 14 ah battery..
    As a separate question. does any one know how to clear error codes from a DPC-18 display ?

    Specifically, like a shark hard case model with a cradle? If so take a look at this...

    So...I am still having this this problem with losing power as well...doesn’t happen every ride but it is annoying when it does...I still think it’s a bad connection but can’t figure out where it could be...any of you guys have this problem.?..did you rectify it?

    You could just have a bad battery connection...riding bumpy roads can affect your battery connection...I was having a similar issue with mine...I wrapped 2 zip ties and two Velcro straps around the battery housing to secure it better...haven’t had a problem since..where is your battery mounted? auto clicker word unscrambler jumble solver
    SWEET!!...very smart...yeah..I just got a new controller on my BBS02...my bike tops out at 49 kmh...custom build is the best way to go..

    Bikes are just too personal and toom uses/ options for a one bike for all. And getting one professionally built is $$$$. Build it how u want it is the only way to go

    Ruffian tops out at 20mph and apox 50 miles. Mine does 40+ and 100+ miles. I built it with the standard Basman frame and parts from Ruff-cycle. But it is powered by Luna products. Bbshd, dual 12.5 ah packs etc. It has many things the Ruffian could never do.......and it was about HALF the price.
    Ruffian $5600
    Mine. $2500
