Thanks it's still a work in progress but I've been riding it for a couple of years now.

Hi guys been machining small parts for the Ol' Crow, some in steel, and others inbrass and aluminum. A lot of fittings, but also started on the Sprag, pedal clutch too. The reduction gear gets a lubrication setup for the oil bronze pedal axle bushing. It wasn"t hard to remove the reduction assembly for service, but this is better, easier and quicker. The oil lite bushing shows no wear after running several hundred miles on the initial application of service oil, they are tough! I used a sealed roller bearing as the outside bearing, but I will use only oil lite for both bearings on subsequent reduction drives.
Not much to see for most of this work, but the varius changes add up to a more dependable and easiet to maintain cycle.
Photos will be posted, as they seem relevant, to follow.

I think you could get away with not using those parallel balancer thingies. I’m still not sure of the need to use them, or how they work. If it has some kind of switching circuitry then definitely get rid of it. Just another thing that can fail. People who build with rc Lipos usually just make a complicated mess of series and parallel connections as needed. I would just splice a parallel plug and connect them together when charged to the same exact voltage. A tiny mismatch will result in one battery charging the other until they are matched and after that, they will never become unmatched. On my build I’ll be putting two batt plugs or running a bus bar block where I can add another battery later in parallel. Have them work together, charge and discharge together. Because of sag you can actually run your batteries a little lower than with a single as it will be half the sag at any voltage. I’ll be using the same cell type if I add a batt, but I don’t have to. It could be any battery chemistry or capacity as long as the voltage is the same. Regen is far too valuable to lose it over some parallel balancing magic.It never hurts to triple check my work and boy it's a good thing I did. In a previous post I explained the benefits of running high regenerative braking for actual help in stopping a bike and this is fact, but after I did a deeper dive into the use of dual and triple battery balancers I discovered a warning against using regen braking with these devices and running more than one battery, or at least the one I bought. So I caution any who might want to run multiple batteries at the same time and going through a parallel balancer to contact a factory service rep about hookup with regen brakes. I'm looking for more info on why this is a problem, but as of now I don't have an explanation, other than excessive voltage feedback during regen braking?
This info bummed me a bit because I really like the high braking provided with regen on my drum brake bike. They aren't great on a heavy bike that has 40 mph speed, so I better slow down.
I'll remove the previous info given.
