    Ebike battery wont charge

    So I was able to tear down the packaging a bit further and find the offending cell groups. I tested directly from the battery terminals and they were the same as the BMS wire readings. If I desolder the 4 wires from the 2 cell groups would the BMS still operate or would I need a BMS with less...

    Ebike battery wont charge

    I'm not sure about the starting voltage, but the bike did power on and had some torque for about 10 mins as I did a test ride when I took it out of storage. The pack will charge for about 3-5 mins before it shuts down if I reset the BMS. I didn't charge through the output port for more than 5...

    Yes I suspected as such. Can I just replace the faulty cell groups? From left to right they are: 3.9 4.1 4.0 4.1 4.1 0 4.1 4.1 4.1 4.1 0.4 4.1 4.1.

    Ebike battery wont charge

    I have a 48v ebike battery that was stored for a long time and will not longer charge. When I attempted to charge it the charger shuts off when the battery gets to around 24 volts. I tried to charge through the output port and disconnected/reconnected the BMS but it still does the same thing...

    E-Bike motor upgrade

    A while back I purchased a Violamart kit for an old bike I had. It is a standard brushless/gearless kit with a hall sensor, PAS and twist throttle. Unfortunately the pedal assist is a bit too strong as it only seems to have 1 speed. I have been looking to upgrade to the LCD3 in order to have...

    Thumb throttle replacement

    Well, the seller for the thumb throttle was able to provide me with the signals for the 3 wires. It looks like in this case it was pretty straight forward. Black -- Negative Electrode Green -- Signal Red -- Positive Electrode The seller for the twist throttle was.. less than helpful. However i...

    Thumb throttle replacement

    I am looking to replace my twist throttle with a thumb version. The wires match in color but id rather not trust that. Is there a specific voltage i should be looking for? Im guessing it is something like ground/5V/returning voltage? Original throttle has on/off switch + power level indicator...

    Hub motor bolts too short

    Yeah, but most of the ones i've looked at seem to be short like this. Filing it would work on one side but the other side doesn't have enough length for filing. Maybe i can get away with only 1 torque arm? https://imgur.com/a/KDPWZpa

    Hub motor bolts too short

    I purchased a front hub motor and the bolts seem to be to short. Is this how they are supposed to be? The bolt barely fits with a torque arm on it. I wouldn't really feel safe with it like this. https://imgur.com/a/G6KFPc1
