There are cheap ones around #$2k and most seem to be between that and about 5 k some are way dearer. I looked at a mates one. He spent 7k. and here I am thinking that $4.5 k for a Suzuki Katana 600 and enough change for a Soco TC at $3k......(Soco is an electric scooter sized Motorcycle. I woul dget one but with a 30km to and 30km home I wont quite make it on a charge so the Katana it is....Oh the sacrifices we make...

Whatever, its gonna tingle just a tad more than the 9 volt battery on the tongue trick

its about that. masses of silly litle 18650's etc all bunched into modules then put in series

How many 18650 batteries are there in a Tesla? The most popular Tesla battery pack contains 7,104 18650 cells in 16 444 cell modules. The entailed capacity by the 18650 batteries stands at 85 kWh of energy.

but for tesla's one battery of the 7000+ goes bad and apparently it takes out the cell module as its throws up an error with the (bms) battery management system, which takes out the whole battery as cant evenly charge - tesla dont replace just one module - whole battery pack time

The guy I was talking too yesterday said he started replacing individual batteries but the taxi drivers would come back a week or so later demanding there money back because he’d done a shit repair job not realising another battery had shit itself. Now he replaces the whole pack, they squeal at the price and whack it on after pay.

Il stick to my old diesel,only 2 batterys il replace every 7-8+yrs for a few hundy.Bugger the after pay thing.

How about the daily commuters to an office in the city get a little electric car or whatever. (or bike or bus........)
Then them and their ideological pole smoking friends can shut up with telling everybody how it should be done.

Then the micro managing bullies in charge of the country do something about the price of fuel (like removing all the tax, until things settle down again. And opening up the oil industry in NZ)

And the rest of the country continues on as normal.

Just my two cents, but sounds pretty easy to me.

Sounds like a good supply of torch cells!

No, it won't be a shit repair job but more likely one batt was on the tipping point and refreshing everything around it made it the weakest link - so it turned it's toes up virtually instantly. There's a guy in the UK that talked about this, he would do electric packs for the minicab drivers and they'd want the cheapest repair possible just replacing the failed batts. He would tell them that there were others on the way out, but no they just wanted the minimum done. Sure enough, next week back in to swap out two more and then a straggler a few weeks after that... Continuous fast charging though so those packs were getting punished.

Owned for 7 months, and an otherwise intelligent person didn't understand how the vehicle worked FFS!!!!

And that there is one of the main stumbling blocks that people report with EV's. Someone gets distracted, forgets to plug the thing in or there's a power interruption and hullo, no go car. Hybrid of whatever sort seems like the most useable option if you're slighty out of town and your only option is personal car transport. Little less of a show stopper in and urban area with bus routes, uber, lime scooters blah blah.

The other issue I see, is if you are in the position of having to do multiple short trips over a day where the destination doesn't have charging facilities - and you aren't at home long enough to charge enough to keep the thing going. Volunteer fireys, mums shifting kids, self employed running dropoffs - its a bit of a pain...

Ditto. I drive a 2005 Mitsubishi Airtrek 2.4L that cost me $1800, which is very comfortable, flies through every WOF, and never misses a beat. On price alone, an EV is not an option, for me. As an aside, with diesel only 10c a litre cheaper than 91, where I live, are they economical now?

The extra cost of RUC does push them a little more expensive, but cost of servicing there really isn't much in it now I find with dealer servicing cost mostly dependant on the oil capacity of the engine and numbers of filters and other hangers on changed out.

Diesels hands down are cheaper for towing.

EV's are gonna get a whole lot more expensive, which will defeat the premise that they will become affordable enough for everyone to transition to them.

Lithium metal has increased in price 6 fold since the beginning of the year (10K USD/Tonne now 62K USD/Tonne). It went to 78K USD/Tonne in April but has dropped back down a bit.

Like coal. Ex Indo, US$65 a ton has now shot up to roughly US$390. Ouch.
