My Ride

[disadvantage]

Today I got another set of statistics from a long, roughly 20 mile ride:

10.401 Ah
372.6 Wh
22.07 Ap
31.48 Vm
828.9 Wp

The bike was kinda frisky today. I got 22 amps peak and 829 watts peak out of it.

However, after this ride, the battery pack was quite warm. I let it cool before recharging. It's my understanding that li-ion fires are self-supporting with their own fuel and oxygen. All they need is heat to get started, and once they have, you can't put them out.

Judging by the 31.48 volt minimum, I probably came close to draining the pack completely. It wouldn't surprise me if the cells are stressed and have lost some capacity.

I must get my Moli pack built soon. I sure wish the Bob & Gary BMS would become a reality soon.

Was the BMC motor black when you received it or did you paint it? The one I received is silver, I think I prefer the look of yours

Roonster, I asked Doug Canfield of EV Tech to paint the motor for me, before he had it laced into a rim.

The motor in the rear wheel is a BMC from EV Tech.

I changed the wires inside of the BMC motor to make it work with Crystalyte controllers, turning it into a Puma motor. My previous bike had a front 5303 Crystalyte motor, but I like this one better. The BMC is half the weight of the Crystalyte, so my bike rides better and is more maneuverable. The no-drag freewheel allows me to coast silently past other bikers and pedestrians. The geared BMC motor provides lots of torque for climbing hills, much more than the Crystalyte.

Just curious Disadvantage, what exactly did you do to the wires to allow the Crystalyte controller to work?
