    A123 Pouch Cell Failure?

    I just noticed my battery charger was going on and off every couple of seconds. I have a 16S1P A123 LiFePO4 pouch battery pack that has been working flawlessly since of 2013. I have a Kingpan 5A charger that always charges my pack to 58V. After shutting down the charger, I checked the overall...

    BMC gear-drive motor won't restart

    I have a BMC hub motor in the front wheel of a cruiser bike. The wheel will start and run as long as there is power applied by the throttle. However, after coasting, the motor will not respond again until it comes to a complete stop and rests for a few minutes. To isolate the issue, I changed...

    Kingpan KP-669 110V or 220V?

    I have been given a V-Power KP-669 charger that is 'repairable'. The charger even came with the part to replace and some advice on doing the job. However, the charger appears to be a 220V charger and I live on a 110V continent. The label on the back of the charger has a lot of Chinese characters...

    Swap Crystalyte 404 guts to 405 hub?

    I have a Crystalyte 404 with a 16 inch (305) 28 hole rim and I also have a Crystalyte 405 with a 20 inch (406) 36 hole rim. I want to pull the windings and wiring from the 404 hub and put them into the 405 hub body and then re-install the guts from the 405 back into the 404 hub body. This will...

    Noisy powerless motor

    I have a Crystalyte 404 motor coupled to an Infinion 35A controller that works flawlessly with my 48V 20Ah A123 pack, but when I put my 15Ah Ping pack on the bike, my motor runs extremely rough and noisy and has no power to move the bike. I must admit the Ping pack is old and repaired but stll...

    LiFePO4 Charger Output Voltage

    Recently, I purchased a 48V 20 Ah A123 LiFePO4 battery pack from OSN Power. I haven't used it yet. This pack is replacing my Ping 48V 20Ah pack made from 16S4P pouch cells. When my Ping pack died and my new pack arrived, I figured that I would just use the charger that came with my Ping pack. It...

    Which motor for longer range? 404 or 405?

    I am taking a bike trip with my wife on our electric trikes. We both have 48V 20Ah LiFePO4 packs. Mine is a V-Power duct tape pack that has been performing well. On my trike, I have the option of running a Crystalyte 404 motor in a 20 inch wheel or I can swap it out for a Crystalyte 405 in a 20...

    Lace a 36 hole hub motor to a 28 hole rim?

    Has anyone ever laced a 36 hole hub motor to a 28 hole rim? In my situation, I have a Crystalyte 404 hub motor in a 16" rim and I hit a stubborn rock and dented my rim. The original rim from the trike has 28 holes and I am contemplating whether or not I can use the original rim on this hub. The...

    Ping Battery Depth of Discharge

    I have a Ping 48V 20Ah V2.5 battery (LiFePO4) with about 20 shallow cycles on it. I only went for short rides and the cycles ranged about 4-6 Ah for the first 10 cycles and more recently, the battery has been discharged 12-14 Ah. There have been no problems with this pack so far. When fully...

    Ping BMS: One LED never comes on while charging (SOLVED)

    I have a new Ping battery (48V 20Ah) and when I charge the pack (5A charger) , eventually one LED on the BMS will blink a few times and then come on solid. Next, the rest of the LEDs will twinkle and then light up solid within a minute or two. All the LEDS are solid except for one and then the...

    Torque Arms, Ny-Locks, Loc-Tite?

    I recently had my hub motor (Crystalyte 405) off my bike for some wiring changes and I noticed that my axle nuts were difficult to undo. They required a wrench even after they were free from the forks. I replaced them with some new nuts that spun freely onto the axle. They were torqued down...

    Why does my e-bike cut out once in a while?

    I am running a Crystalyte 405 20" FWD on an Evox LE semi-recumbent bike with a 20A pedal-first Crystalyte controller and a 48V 20A V-Power LiFePO4 battery. This morning at -10C (14F) I rode mainly under power (70-80% throttle) and after about 8 kms (5 miles) the motor skipped a beat, then a few...
