    Yes out of the 46 cells I originally bought I installed 45 (one spare) I had one unusable cell so swapped it out with the spare, It reached the charge voltage I set in the BMS (4.45v) well before the other 45 cells , thus preventing the other cells reaching 4.45v as the BMS switches off the charger to prevent any one cell over charging. 4.6V is considered 100% SOC , anything over 4.8V kills the cell dead.

    Of the remainder of the 45 cells 3 cells reach the Low voltage I set the BMS to cut off (2.9V) whilst the rest of the pack is still at 3.2V , so 3 cells are preventing the Battery from full useful discharge. 100% discharged is 2.6V (anything under 2.4V is dead - unrecoverable) And One more Cell still was going high early.

    This is my fault for buying cheap arse SinoPoly Cells at $222 each , instead of paying $288 each for CALB cells .
    (basically the same cells but clearly without the QC checks)

    Full DOD is from 2.6 to 4.6v , I have my BMS set from 2.9 to 4.45v so I can never overcharge or over discharge a cell.

    In real terms it made no difference to range per Kwh , I just had access to less kwh.

    A few weeks ago I have received 4 x new cells & solved the battery pack problem. I also beefed up the back end with a TrueTrac & Ashcroft 24spline axles so reprogrammed controller to make full use of regen ( thought it would snap an axle before) & I get more km per charge as a result of that too.

    If you use a public tesla station how many amps will it push, do you restrict the charge rate?

    Over the years you will have to take very good care of those batteries. I imagine if you ever fall short of a destination you will have to decide if its worth pushing a higher dodc or call in a recovery. And there might be times where you are tempted by a faster charge rate.

    The required level of care is easier for some than others. Having made note of your attention to detail I rekon you might just make it. Keep us posted.

    yes , thus the article on the Tesla that had covered 400,000 miles and had to change out 2 battery packs because he regularly fast charges and frequent charges to 100% against handbook advice.

    Occasional fast charging and occasional 100% SOC charging wont be an issue , EG normal use = home charging to commute & occasional long trips with Fast Charging = no dramas.

    I am not against the principle of EV's. Like so-called Smart cars, they are useful to a certain number of people, in certain situations. What I do object to, is the green-washing, almost to the point of religious fervour, by some sections of the media with (as usual) little or no regard for reality. They are talking of tens, if not hundreds, of thousands of diesel vehicles being arbitrarily banned from cities throughout Europe, as if this is a great leap forward. They have effectively destroyed the resale value of a big proportion of the European car market, the majority of which are privately owned. If you have ever traveled through a city late at night, or been involved in transport/distribution, you would have a small inkling of the amount of heavy vehicle (read diesel) traffic involved in keeping a city running, from stocking the shelves, to carting away the rubbish. But apparently, their politicians must have all these problems figured out!


    I also hope that the EV owners realise that a commercial rollout of charge points will inevitably mean that the fee for using them (a "charge/charge" if you like) will increase, thus making less economic sense to own one, rather than an ICE, unless used only for short trips, charged from your home power source (the cost of which will never go up, of course!)


    I haven't heard anyone yet giving actual figures of how much their home power bill has risen, since purchasing their EV. There is also, as I understand it, the need to have an electrician install a 15 amp point to charge from, and, if wishing to take advantage of off-peak power prices, a separate circuit for that. In general, the Australian power distribution system (like the data system the NBN is piggy-backing on) is barely up to capacity for the loads it is trying to handle now. Imagine the hue and cry from the power retailers when their "gold plated" systems start buckling under the load of multiple EVs in a street all plugging in at around the same time. Back to "brownouts" sound like fun?
    There is nothing to say highway charges stations won't rival small shopping centres and be sizeable solar/wind power stations in their own right. Just like service stations on the side of highways these days have grown into feeding stations with large car parks more than service stations with mechanical services, charge stations will similar but just have more parking. There is also nothing to say as glass has been developed to become a solar conductor for high rise buildings, the paint or surfaces that receive wind don't also become charging surfaces in their own right on a vehicle. Its what the technical revolution is all about. I'm sure the farmers were very concerned at the end of the farming revolution as the industrial revolution phased them out.

    Its also not green washing, the common belief that greenies hinder commercial growth needs a big re think. Its middle to late aged men in positions of power of traditional companies that can't deal with change that hinder commercial development, the sacred CEO so to speak. The potential jobs of the future far exceeds whats on offer, plus growth that is far more sustainable for the planet, new manufacturing opportunities, and recycling options are just so big and broard compared to keeping fossil fuel as the business as usual model. It seems to be only America and Australia that are willing to watch the earth slide away while the rest of the developed world is keen to embrace EV and sustainable technology. And yes just like the horse and cart became worthless, so will anything that uses fossil fuel to get around for the vast majority of us.

    Good job those oily oldies in profitable positions dont live forever. But they will be vocal for another four decades at least.

    When we look back at history, we see rapid change. But in our own lifetimes, we dont get to see that much. Out with the old, in with the new!

    Don’t forget the hover board.
    I think it’s nice that the kiddies these days have such vivid imaginations.

    indeed, but these days we have the internet and far lees controlled advertising from the cash cows. They may use politicians as pawns but they can't stop people talking. They are working on it however.
    Droughts in places that should be cold, heat waves in places that don't have heat waves, wild fires, floods, cyclones at ever increasing intensity, ice melting like it has a flame thrower on not, and much of it is random and out of season. Just what those whacky climate change scientist have been saying. Not all 100% accurate in intensity, but 100% in activity. I used to eat meat but never liked the amount of land clearing I witnessed travelling, it always didn't sit well. So I changed to roo thinking that would be better. Then I happen to watch a couple documentaries on the free internet that a client told me about, it all made sense from my observations and experiences, so I just gave up meat and dairy full stop and have never felt better. Physically and mentally, and I feel like I'm 25 although I'm 47. I give blood, have no health issues, and can walk 6 hours with 24kg rucksack on my back no problems. This change is almost 2 years ago now. So rapid change is possible, and I would argue for the better financially, personally, family, planet wise, and don't see any negatives to it except not following the crowd.

    some viewing if your interested

    Hallelujah, pass the ammunition!
    There aren't any more pious than those who are recently converted.

    Thank goodness there are only a few people who have converted.

    I thought about reporting this thread for the emerging religious fervor.

    FACTS hurricanes have diminished according to NOAA, wildfires in California are only a fraction of what they were 200 years ago. It's just there are more people affected. And no forest thinning.

    FACT The low point of ice an the Arctic was in 2007. It has been recovering since. FACT Polar bears are increasing greatly in numbers

    FACT Coral Bleaching on the barrier reef is 10% more than 200 years ago.

    FACT the Antarctic is increasing in ice mass, despite the 70 or so volcanoes recently discovered under.

    Science smience , who cares about the planet anyway.

    I converted for selfish reasons .

    In my Landy I Never have to queue up for or pay for petrol again.
    I never have to open the bonnet for daily / weekly checks / 100% reliable !
    Never have to put up with the horrible exhaust fume stink & back of my head smelling like an oily rag when've ever I drive with the canvas rolled up.
    I can drive to the local shops 5 minuets away from dead cold & not need to warm the engine up for fear of buggering it on short trips.
    4WD ing is a way better with 100% torque from zero & woo hoo I have hill descent.
    So many other reasons , all of them selfish , As I said before I'm not a greenie , nothing I do will save the planet ,
    ... but if lots of us do something ???

    The billions of people in the Northern Hemisphere currently experiencing record heat waves would consider you to be talking out of your Southern Hemisphere...
