Also, current lithium chemistries of the usual suspects don’t like the vibrations seen off bitumen.Only a Landcruiser in form and probably selected as no suspension mods would be required for the weight of the battery conversion, not going to be 'cruising the land' any distance in an underground dodgem that goes on charge twice a day.
Basically a city vehicle that drives around a site/plant with favourable emissions for underground use.
Good info !Also, current lithium chemistries of the usual suspects don’t like the vibrations seen off bitumen.
oodnadatta track corrugations might do in a few cells.
Vibration inducing capacity loss is one thing, letting the red devil out of cells is another all together.
Engineering solutions will be found in time.

Yep, same area of concernWhat about emtbs
Interesting I have not seen anything about this noted in relation to EV's or EMTB's in general consumer stuff.Yep, same area of concern
I’ve plans for researching this area, take a bunch of cells, panasonic, Samsung, murata, carefully sort them into quality groups, pana and Samsung will fall into 8-10 groups, murata 2 ( it’s the old Sony chemistry).
Once sorted properly, split up, half of each group goes into a paint shaker style rig, others static. Shake the bejesus out of them while under discharge, and compare to their static mates. Over 500 or so charge/discharge cycles.
Anecdotally, I’ve seen reports of owners buying two identical packs, one used for the MTB, one for the flat bar commuter, and the flat bar bikes pack being discharged fully daily, with 2-3 times the cycle count, with more capacity then the MTB pack, so I will create a controlled experiment and hopefully make some discoveries. Higher discharge rates do make a significant difference, if the MTB is using 20Wh/km and the flat bar commuter is using 10Wh/km this alone can account for a massive portion of the difference, but I am beyond curious.
Here is a very recent article summarising the current state of affairs, fair bit has happened recently. Previous research I had read said something along the lines of this “lithium ion cells as used in modern EV’s, subjected to simulated on road vibrations, as typically found in Europe, shows cell capacity degradation is predominantly attributed to cycle count, and not vibrations, by an order of magnitude difference. Off road level of vibrations and their contributions to capacity depredations are not yet known and warrant further research”Interesting I have not seen anything about this noted in relation to EV's or EMTB's in general consumer stuff.
That thing is like a rocket!
Incredible machine.That thing is like a rocket!
Must say the first thing I thought of watching that was Le Mans 1955.Incredible machine.
All with the spectators within the danger zone. One tire failure away from a mass fatality when it barrel rolls through the crowd at Mack Jesus.
You don't know it yet. But you already have an entry in the f/wits thread when you park you car in the garage with the bikes on the roof...hence waiting for roof racks
Whats the cost on a new glass roof on a Tesla I wonder...You don't know it yet. But you already have an entry in the f/wits thread when you park you car in the garage with the bikes on the roof...
Yep.Whats the cost and lead-time on a new glass roof on a Tesla I wonder...
My brother would know. Had to get his replaced on his model 3 when damaged in a hail stormWhats the cost on a new glass roof on a Tesla I wonder...
Ah those bales of hay are plenty safe enough! lolIncredible machine.

I wonder if "can be used on existing...trucks" will work as well as converting heavy diesels to LPG (ie: frequent, unscheduled engine rebuilds). I do think these synthetic fuels will be valuable for future heavy vehicle applications, but remain skeptical about the compatibility with existing vehicles/engines.Porsche to build Australian efuels plant in Tasmania, operational from mid-2026
A multi-million-dollar investment will result in carbon neutral synthetic fuels being produced in Australiawww.whichcar.com.au
They are not like converting to LPG, this is a chemically identical fuel that has to meet existing fuel quality standards. You might tell the difference in extended oil changes as its a more "pure" fuel, but otherwise it behaves the same.I wonder if "can be used on existing...trucks" will work as well as converting heavy diesels to LPG (ie: frequent, unscheduled engine rebuilds). I do think these synthetic fuels will be valuable for future heavy vehicle applications, but remain skeptical about the compatibility with existing vehicles/engines.
Aviation is the best example - you can be very very assured that engine performance and longevity is considered for commercial aviation! But it has been approved as a drop in replacement afaik.I wonder if "can be used on existing...trucks" will work as well as converting heavy diesels to LPG (ie: frequent, unscheduled engine rebuilds).
