Re: United States Ends ICE

Progress ends ICE. Solar+battery+autonomous = 10X cheaper transportation. As soon as that happens it will be a steep adoption curve. We'll be half done converting to service-on-demand autonomous in 5 years and completely done by 2030. Most of what trucks do now will be done by smaller autonomous veh...

Re: Kawasaki KXF 250 QS 138 70H conversion

Beautiful. Looks like you retained the stock motor sprocket location and replicated the stiffness of the original gearbox to maintain original chassis engineering. Seems like the CG is probably the same, too.

I wonder if wax would dampen the chain sound without being messy?

Re: Need torque - Manco 615 with BLDC/MY1020 72V 3000W motor

If its the battery low-voltage circuit cutting power, you might only need more or bigger batteries. Does it torque stall more easily as the batteries get lower?

Re: Thoughts on using SLI/AGM batteries

If you never discharge past half capacity and recharge immediately after any use (not 'a few hours later'), lead can work. A good example would be a lawn mower that gets plugged in anytime its not being used.

Re: Understanding and Using EGO Power+ Batteries

The +\- terminals on the ego battery bypass any electronics, and are connected straight to the cell string. The tools decide when to stop accepting battery power. Any BMS is only for the charging/charge display.

Re: Crowd funding DIY Prototype Insurance Sovereign Being

Vehicle insurance will be as dead as ICE's when they dissappear from roads, with half gone within 5 years. The more pertanent question will be how 2-wheelers in general will coexist with autonomous vehicles. Will society chose to fund roads for anything but autonomous vehicles?

Re: Ebikes are they AC, DC or?

https://en.m.wikipedia.org/wiki/Alternating_current
Alternating current (AC) is an electric current which periodically reverses direction, in contrast to direct current (DC) which flows only in one direction.
Ebikes have DC motors that are electronically commutated through 3 successive phases.

Re: Why are two speed transmissions not more prevalent?

One reason is that you can size your motor/controller/battery to the peak load and then run them at partial load without a significant efficiency hit.

Controllers and batteries are advanced enough now that transmissions aren't part of the path forward.

Starting your car just to maintain your battery seems unwise, expecially if the car doesn't get fully warmed up. Modern cars' computers draw enough current to justify a maintainer charger if you aren't using the car daily. If you can't plug in, attach a 'booster' battery that you can easily bring in...
