Re: 12v lithium batteries can't be paralleled?

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...

Re: 12v lithium batteries can't be paralleled?

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...

Re: 12v lithium batteries can't be paralleled?

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.

Re: Kona EV Brake recall!!

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...

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.

Re: Esperance Zoe.

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...

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

Re: 2020 Ioniq

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?

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?
