I see that no-one has responded to this post. Any reason? Rush has followed up asking if we want to order any. I'm not totally sure I want one either but what's the reasoning from others? Johny, I didn't see your post. But on reading it. I thought over it and I'm inclined to wait until I see whethe...

I have cut out my lids from 3mm polycarbonate (not cheap -- nearly $50 for a 915 x 650 sheet at the local Hardware store) to give a secure protection of the terminals and future BMS, and to keep the celltops visible. But the faces facing the a/c condenser in front, and the bases of the lowest boxes ...

BTW, In Australia and New Zealand, in DC terms, LV means exceeding 120 Vdc but not exceeding 1500 Vdc. And HV means exceeding 1500 Vdc (AS/NZS 3000 section 1.4.98). So I use the terms ELV and HAZV as defined in NCOP14 Section 2.1. Thanks for the guide to correct nomenclature. Does your rearmost box...

Volt outsells Leaf 3 to 1 in the US.

It sounds like this person is confusing capacity reduction with life reduction. A battery that has lost 80% of its capacity doesn't still have 20% of its life remaining. It will last such a short time under discharge (when it's needed) as to be unusable, so it's useful life is over well before that...

Hi guys, out there. Where are you positioning your inertia switch? Right next to a (fused) auxiliary battery, or just 'before' the ignition switch? In the latter case, one would still have many functions available even when the switch is tripped; in particular, hazard warning lights, and only the HV...

Neville, yes, of course.
I can certainly let you know about my speed signal when I've got the rear wheels spinning.
The question is though, what is the difference if any, between my 1998 instrument cluster and yours.
I have a circuit diagram for mine, complete with connector pinouts and colours.

Speaking of crumple, my "other car" was a Jaguar XK and I severely crumpled it last week, so don't do as I do, do as I say! Oh I'm sorry to hear that. Bummer! and I hope not for my Beemer.

Well, the solution is obvious! Don't crumple!! How'd your pwr steering pump driver work out? So simple. Why didn't I think of that? I fried the micro I was using and have had to wait for another. But the mechanical system works: I put the wheels on the floor and applied 12V to the pump and hey pres...

I'll be using a microswitch or hall switch with a magnet mounted on the filler door.

Just wondering if the engineers in NSW are happy with you putting the front battery box in what appears to be the frontal “crumple” zone of the vehicle? Although those boxes are close to the front I don't see more than about 10-15cm of difference from the original six-cylinder engine which pretty m...

Slow work this last month. I visited family in Perth and unfortunately just missed the monthly AEVA meeting. I have now bought a Toyota MR2 power steering pump. (1993 I think.)

Thanks, the three of you, for your thoughts on cell-swell. At the row ends, even though the cells are hard up aginst the box, there is still a 1 to 2 mm gap in which I could insert some steel.

I don't see how your battery boxes clamp the cells though, or are you not concerned about that? With the exception of the two boxes under the rear seat which will be packed at their ends, the cell rows have almost no play whatsoever in their boxes. So the only expansion would be end faces, and that...

The chargers arrived recently. I ordered two TCchargers, each 2kW, which can be paralleled. Strangely, that was cheaper than one at 4kW, and it provides flexibility in charging. Each charger draws just under 10A from the AC supply, and by having two chargers, one can avoid the difficulty and expense...

Yes, for the CALB SE100, and for the SE60. The new grey series also uses this size for some types.

From the photo of the cell-top board I can't quite see how tall the components are. I suppose the headers are the tallest, but presumably they could be replaced with right-angle types if there's insufficient headroom. Also, my cells have a 81mm terminal pitch, requiring a longer pcb, and therefore p...
