    My ebike made it on Discovery Channel !

    Any fellow Canadians out there happen to watch Daily Planet tonight. If you did you may have caught a short clip of Jay taking about my bike. I uploaded a video to their site a few days ago (at the request of my 8 year old daughter) and to my surprise they gave it a whole minute of airtime :D ...

    Crystalyte 18 fet cycle analyst connections

    I just received my crystalyte 18 fet controller from Max that came with the pigtail for the cycle analyst. I replaced all the phase and power wires for larger gauge wire, replaced the the caps with 160volt caps and changed out the resistors so it will run at 100 volts. Every thing works fine but...

They will be charged as 2 15s2p packs. I have built two 15 cell Goodrum BMS boards and will be mounting them in a small pelican...

    72v 50amp 4110 controller error codes

    Just replaced my melted and unfixable (for me anyway) 4110 modified analog controller with the new 4110 50amp controller from ebikes. Previous controller worked great for a year running at 50 amps and then just failed after a wet ride to work (think some moisture got in). Replaced all the fried...

    For anyone else who decided to destroy their 36v ebikes nimh chargers by connecting them to the series connected battery packs (72v), I finally repaired mine .

    Stripped threads

    While replacing a flat (screw) before my ride home from work last night I was unable to fully tighten one of the axle nuts on my rear 5304. After removing the nut it looks like I stripped a portion of the threads on the axle. I guess I was a bit overzealous tightening the nuts due to not having...

    Charging warm batteries ?

    Just wondering how long I should let my 18 AH 36v NIMH packs cool down for after a hard ride before charging . After sitting for 2 hours they are still slightly warm to the touch so I have been waiting 3 hours before my charging timer turns on but then I can only charge them back up to 90% (...

    Battery fuses

    While I wait for my 72v 35amp controller to be repaired/upgraded, I was wondering what to do about battery fuses for my 2 x 36v 18ah nimh packs. They came with 20 amp blade fused which will need to be replaced. Can only find 30 amp fuses at Canadian Tire . I believe they make 35 and 40 amp blade...

    Is it a problem to mix battey packs with different Ah ratings? Trying to decide which nimh packs to get for my bike . I will probably go with a 5304 in the rear and was planning on 72v . Was considering 2 37v 18Ah packs (23 lbs each), mount one in the frame and one on the rear . But I think...
