Re: Lipo vs Lion

Not quite sure why you would think that, ..... .....because that is what you linked to when asked what you would suggest... ...but I do believe the Graphenes and the HRB are better than the Multistars, (that which did not even make the list) for a hobbyist whom is not building, but buying a lipo.

Re: GM retreating into its shell ?

Talking bollocks ? ...check your tax info ! What is your problem here ? NZ has a different economic base to Australia and a different tax structure, that actually results in lower income earners (<$50k). paying MORE tax in NZ than their Aussie equals ! AND. the income earners up to about $90k will p...

If you want to learn how to make a super light, super strong, thin Carbon body shell for a Velo, Aircraft, or anything,.....watch a few of Mike Pateys videos.

Re: GM retreating into its shell ?

Its no easier than designing an ICE for optional controls...
there is not much direct interaction between the driver and the engine /gbox in a modern auto
the compliance testing for different countries is likely a bigger problem.

Im sure some other manufacturers will do similar business analysis and pull out of Australia (VW, Tesla ?), but the world wide RH drive market is too well established for most to ignor.

Whilst acknowledging the risk of lipo and any other high energy source (fuel cans, gas cylinders , etc ?)..
... what battery system might you suggest then John ?
Maybe some of those 18650s that burnt up in Laptops and ballance boards , Teslas, etc, ??

....... Could Australia ever make cars again? I doubt it. But we could make parts for cars and export them. We could , and indeed we do. But sadly the same economic factors apply. Even fully automated (non labour) manufacturing has to deal with the realities of tax, energy, compliance, market scale...

You seem fixated on high Crate, high cost, low capacity, products.
They are no comparison to the 16/20Ah multistars .

Many vehicles, fwd cars , rear engined rwd cars ( VW Beetle), etc have differentials built into their TRANSMISSION assemblies.

. The sprocket is 5.5" diameter. The pillow block spacer is 1" PB bottom to ctr of bore is 1.5" Ok, but using those dims,. You could get a 9” dia brake rotor on with an extended JS But no big deal if you are committed to the existing set up. ..( but its good to know my eyeball is still calibrated !...

Just as a bit of side info, this video posted on another thread explains some of the business reasons why some major ICE manufacturers are reluctant to jump on the EV bandwagon

There is a 2 nd video that deals with efficiencies also.

We're not going to have a fast transition from " the Labor party wants to steal your Utes and weekends with electrics..." to turning around and embracing it.

Re: C Cab Hot Rod Power Advice

Just eyeballing here,..but it looks like there is about 4-5” vertical clearance between the JS and the axle ? That should be enough to allow a 9” brake rotor , but even more room if you move the JS rearwards from the axle line.......but maybe my eyeballs are not as precise as i think they are :lol: ...

I agree though, it seems a fairly useless metric otherwise. Who discharges at .2C? Lol
Yes , 0.2C is a defacto industry standard to allow comparisons
Who uses it in practice ?... possibly a few million laptops, and a few billion cell phones ?
Not everyone rides an Ebike or drives a EV.

Re: C Cab Hot Rod Power Advice

moving the motor mount and JS to the rear, creates room for the brake disc under the JS and shorten the chain length. Using a longer JS to a bearing on the outer rail. ( close to the wheel). Reduces the bearing loading and stiffens the JS assembly to minimise movement under load. OK if its too late,...

Re: C Cab Hot Rod Power Advice

A suggestion fron these idle hands.. Locate the motor as far back as possible. Move the JS back as close as possible to the motor ( shorter chain is better) Extend the JS to a pillow block on the outside frame rail , just use 2 pillow blocks, the one nearest the 11 T sprocket, and the one on the out...
