Looking at the specs, the 460Ah capacity is @ a 0.2CA discharge rate, not the 0.5CA rate you are discharging them at. I found the Sinopoly cells had a similar issue, their advertised 100Ah cells would only deliver 100Ah down to 2.8v if the discharge was restricted to 0.2CA. At the 0.5CA we use for t...

What size cells? I'm experimenting with reviving near dead cells for house battery use and using the dead cells electrolyte to top up cells that have vented some of their electrolyte. The electrolyte harvest and transfer can only be done on very cold mornings, otherwise it simply boils away before t...

I could paint it rattle can flat black for that stolen look

Stolen stealth, can't hear it or see it

All the colours!

Known as "Bogan camouflage" Or a taxi respray

I guess time will tell. Maybe I just have a better eye for picking out different colours across a vehicle and that highlights where repairs have been carried out. A quality painter can even duplicate the ripple effect caused by the factory paint and bake method. They use a different paint to that us...

Not a lot of panel beating or spray painting experience in that comment. Sure, you can spray the panel and then fit it, but then you have to spray that panel and the panels adjacent to colour match/flow the different spray techniques and baking techniques that produce different colours from the same...

Vehicles that used hybrid fuel supplies like LPG or CNG as well as petrol or diesel must have the LPG/CNG tank removed before they go into the baking oven. These days just about every repair must go into the baking oven because that is also the spray booth where the stray paint and vapours are eithe...

Maybe see what components you can fit into that space and make the cradle that supports them part of the structure that also supports the motor weight. That mount is really only to reduce the see-saw effect on the two side mounts by carrying the weight rather than acting as any sort of torsional mem...

If you use Loctite you don't need to use anti seize type products because the Loctite fills in the spaces where the problems can occur and acts as a lubricant on the thread while assembling. Just be care what grade you use because you can't really heat the bolt or thread area to release the Loctite....

Longer blots maybe? The spacing still needs to be the same thickness so using a thinner plate isn't going to improve the bolt stick through at all.
If you helicoil the thread holes in the ally it will be a lot stronger thread wise.

I'll keep an eye out for anything that is on the horizon. I have 28 x 100Ah Sinopoly cells, but you need 45 cells so that is no good to you. I probably have the other 17 cells needed as 90Ah Thundersky cells (same physical size), but I doubt they would be suitable for an EV battery because they have...

my ev...is looking for a 2nd hand 144v lithium batteries

Nope seems clear - lithium batteries, 2nd hand, 144V for his ev.

Ahh..... helps if you read with your eyes linked to the brain eh These were 160Ah Winston cells, not sure they would fit in the battery area available.

Hi Dan, are you looking for a house battery or an EV battery, cell size as well as expected load need to be considered as well.

T1 Terry

Pity this thread started a few days too late. I could have supplied a 144v 23kWh reconditioned lithium battery pack for that price, complete with a 12mth back up warranty if it was for a house set up, would add the warranty if it was for an EV set up though, too hard a life is possible in an EV. I h...

This was on Car Sales https://www.carsales.com.au/cars/detail ... 239/?Cr=65 around $130 more than the one Brendan found, but unknown what city that price is based on.

There is all sorts of info here https://www.thebackshed.com/windmill/home.asp if you want to build your own or improve the performance of the Chinese things with the noisy blades.

Mmmm....... Personally, I'd get it welded by someone who was really good at the job to make sure it was square to the base plate. Just too many bolted together pieces to ensure good alignment every time and it remain aligned. Just from experience as an industrial fitter for many yrs

T1 Terry

I believe this was for sale on evilbay many moons back but I wasn't allowed to buy it then ..... bugga, it would have been great to bring it back to SA where it was built when we moved over here. The one who controls the finances said it was just a toy with not enough range and no practical use .......

If the plan to weld this piece of plate to the piece attached to the motor, then the holes for the driveshaft mounting drilled and helicoiled for thread strength? Will there be enough support positions for bolts available on the back of the motor? I'm guessing you would need to add dowel pins to ens...

I can see long drives and rapid recharging, then repeat, being a problem for all but the most sophisticated battery/motor/inverter/charger cooling systems. Even Tesla reportedly limit the rapid charging after a number of back to back fast recharges. Rather than just turning off, the Tesla apparently...

I had on of these little pocket cars with the 2 speed auto many yrs ago, couldn't keep motors up to it. I thing a direct drive into the 2 sp transmission, rather than the torque converter, would make a great little run around car using a much smaller motor than a direct drive approach would require....

Hmm, true. I guess taking to a lithium battery pack with a plasma cutter will have to fulfill my destructive tendencies

Now that would make a You Tube video that would go viral

T1 Terry

Any estimation on price? And what is a "hairball drive controller" hopefully not a comparison to something the cat threw up

T1 Terry

They use 15inch+ petrol power grinders to cut cars in half for half cuts, what a sight to see when the guy doing an EV goes through the battery in the floor :lol: When I worked for the rail maintenance mob, they had a number of these petrol powered jobs with the big cutting blade that they used for...

In the picture of the complete unit I can see a computer on the back of the gearbox, separate from the motor controller. I presume this is the gearbox controller. There is a large bunch of wires leaving it that has been cut off.... Looking through the other photos, there are a lot of spots where a ...
