Happy to report that OSN Power sent me a new A123 pouch cell (20Ah) and I opened up the pack. I immediately saw a leaking corner on the third cell in from the positive end of the pack. I suspect some kind of physical failure, but the pack was very well protected in a padded plastic ammo box...

Thanks fechter, I have disconnected the BMS and I have a single cell charger. I am still trying to figure out a suitable load for a single cell discharge without buying a CBA IV from westcoastmountain.com. Any ideas? Something safe ;-)

Thanks Agnuism for the kind offer.I have a new cell coming already. Please PM me with your offer including shipping to Ottawa, Canada. I will probably need to start replacing cells on this pack now that one is showing signs of trouble. I have had some temporary success by replacing cells in a...

The pack was from OSN Power (2013) and it is 16 pouch packs with bolt on connectors. The foil connectors are folded under the metal strips.

Today, all cells are sitting at 3.35 still except that one cell is now sitting at 3.2V. Do you think I should I should replace that cell? How can I test it to see if it is faulty?

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...

I just checked the voltage on the hall sensor wires, I disconnected the green controller hall wire from the yellow motor hall and put an alligator clip from my digital multi-meter on each wire and carefully rotated the motor backwards until it registered 13.5 volts with the controller turned on...

The halls and phase wires are currently set up as per the link in teklektik's previous post and the combination spins up the motor from a standstill. If I hold the throttle on, the wheel keeps turning under the motor power, but once I back off the throttle, the motor will not restart. Very...

I already have the wires bare from the motor and controller side. I have been twisting them together and using small blue marrette screw-on connectors to keep them tidy until a final solution. I have the tools and parts to replace the Anderson connectors for the phase wires and I have the...

Yes, I picked up the parts used, but the old Crystayte controller is supposed to be the one that works for this BMC motor. It was part of a working bike project, but I never saw the old project in action. The controller is a Crystalyte with a red push button power switch. The controller's hall...

Thanks teklektik, your explanation of the heat causing the problem is very convincing. This motor is very loud right now. Would an incorrect hall /phase wire combination lead to unnecessary heat and noise? The symptoms occur even on the bench with no load on the motor, just free spinning in the...

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...

I tried to upload the pictures, but I will need to shrink them down to 512kb first. Can I plug this charger into the stove or dryer plug if I change the plug?

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...

Both are front motors. I will verfy that the side covers have the same bolt patern before I begin. I am waiting to borrow a big puller to avoid damage to myself and the motors. I've heard some people can pull them by hand, but I am cautious. Ypedal, do you use a puller to get them apart? Is...
