Well the nickel plating didn't happen before Christmas, which means nothing will happen until after January 4th. After spending the last two days indoors with the aircon on full blast (and not drawing from the grid - thanks to solar ;) ) today was cool enough to attack the Prelude battery again. I s...

Is that a scorched armature winding?

I have experience with both circuit diagrams drawn. The parallel first, then series arrangement is more reliable, in my experience. Of those two diagrams, are you suggesting the upper one is better? By the way, if you open up a large prismatic LFP cell, you will find 3 jelly-rolls wound up and paral...

Yeah I did a stack of that snooping, but the tell-tale was the spark once I pressed the On button. It seems strange to me that the two transformers are wired up in series, but maybe that's just part of the circuit. I'm wondering if the neutral-earth arrangements in Australia are not conducive to how...

I think that's the same place the bath was bought from. And if the generator is the same, it too might blow up on switch-on.
I guess I'd like to know that the transducers aren't stuffed, and if not, then maybe a more reputable supplier can fit the bill?

For lack of a better place to put this thread, I figures starting here might be a good place. Ultrasonic bath.jpg https://www.bjultrasonic.com/shop/power-adjustable-ultrasonic-cleaner-130l/ A friend bought an ultrasonic cleaning bath from China for about $3000 landed. Not knowing what to expect, and...

It depends - when I build LiPo cell packs, the series buslink is a piece of 2 mm thick copper, and it serves as the parallel link too. I have never seen an internal short fail that way. I have seen cells with a small self-discharge bring the entire parallel group down to zero though. Which sucks, bu...

What do you mean by 'lets go'? If it forms an internal short, its voltage will drop and the cells in parallel with it will dump current until the buslink melts. If it goes open circuit the capacity is reduced, the DCIR increases and will result in voltage sag across that one cell group. Parallel fir...

Are these RV failures lead gel batteries? Or LFP?

If it's LFP, the best option is to parallel them at the cell level, and that means having all the battery in one place. Which is not always the easiest option.

I think @4Springs recently bought some and bedded them in for the Brumby.

I think a class action is unlikely. There was a collection of names of folks who were keen on pressuring Nissan about their lousy battery packs in the 2012 Leafs, but in the end, most of those people went out and bought new EVs with better batteries. Most concluded it wouldn't be worth the hassle, a...

For me it was the hoist. That was $3600 well spent from day one. I can't put a price on my sanity crawling underneath cars in the dark...

Hi Luke - hope this project is getting the attention is deserves? Setting up the workshop is a priority though. I bought a house with a big shed and had a hoist installed so I could convert the Prelude.

Hi Boris, antiscab also has a Zoe but it's not had any trouble that we're aware of. 22 kW onboard charging is pretty handy. You can try one of the Fast AC chargers on the RAC network. If that charges OK, go for a long drive and come back and try it again to see if it faults. Hopefully it's not a hea...

Hi WA Zoe Guy (hopefully we'll learn your name soon!) - I drove that car to Esperance and experienced the difficulties. It appeared to me that the car was fine for daily use, but after driving 200 km and charging it at 22 kW, it wasn't happy. It only started to charge after things had cooled down. R...

Is this made abuntantly clear wjen you buy a Tesla?
Cause that's one of a few reasons I didn't get one.

*Frenchmans spit*
I doonot like this po-wer!

Nothing wrong with pinching a phase and neutral from the plug, just make sure you pass it through a mobile RCBO.

I reckon @suziauto could help here?

I generally get about 350 km driving to work and back for 4 days in a row, but it means a long weekend of solar charging. So I tend to put 10 kWh in each night from the house battery.
On the highway 260 km is possible at 100 km/h and no aircon. Maybe 220 km at 110?

Christmas party might be a barbecue by the Camfield. Place is booked out from arsehole to breakfast. Tis the season...

Populating a module is the easy bit... Spent today unboxing the remaining cells and cutting up sheets of G10FR4 for the enclosures. Once the modules are fully terminated I'll build an enclosure around it and fill 'er up with resin.

Hopefully these trends continue!

I wonder if the balance will improve with more short (10 to 20 km) drives and recharges?

Apparently this will be released in Australia next year.
Not the greatest range, but priced accordingly - small range means low cost. Maybe $43k drive away?
