December 8, 20223 yr ...but as an anti car person you were so busy looking for fault you couldn't be bothered with it. Drop the arrogance, as I said you know F-all about me. You see [mention=4]flecc[/mention], you're making arrogant assumptions about me too when you actually know F-all about me too. I sold my Mercedes at my main home and so now choose to use public transport (in a city), but I still have my diesel VW van at my holiday home for day trips with my e-bike. Does that make me "anti-car"? I'm not looking for fault at all. In essence I agree with you. You're rising to the bait. I could buy an EV... or any other new car.... but I question whether I should. That's the debate.
December 8, 20223 yr electric cars are now a consumer product so when the warranty ends so will the life of the car be over as parts like on a 10 year old phone will be obsolete. bosch said they would support there products for 10 years so my time is up but the point they do make a batt that will fit my bike just software locked out from working means ill never buy another one esp with can bus bs and planned obsolescence. so if you have the cash buy one use it until it is out of warranty bin it and buy a new one. or do a Eddie pj and ramp the shit out off it in thunder storms to the point the bearings fall out of the motor get a new one under warranty from bosch sell it after 2 years and start again with a new bike https://www.vintagevoltage.tv/ at least you will have control of the controller and more easy to change batts and parts.

December 8, 20223 yr I think partially that is what we see in the used ebike market for mid drive bikes SW, quite a few up for sale before the 2 yr warranty expires except sellerswant top lolly for a worthless bike that is likely to be scrap should it go wrong soon after.

December 8, 20223 yr I still have my diesel VW van at my holiday home for day trips with my e-bike. Does that make me "anti-car"? Oh dear, using a diesel to carry a bike makes you a villain in many eyes! You said we are using the same hymn sheet but that isn't the case in many respects. My home is deliberately as minimal as it could be, bought 55 years ago for entirely green reasons when I could have bought anything far larger. I wouldnt dream of having another home as well, whether for holidays or not. The closest I ever got to that was a boat on the South Coast for few years. Obviously we are both very environmentally inclined, but in rather different ways, and I suspect we have somewhat different visions of the future. .
December 8, 20223 yr Another thing with LFP one can't really go by voltage regarding discharge as the curve is very linear and typically only 0.35v for full to empty on single cell basis, one would need to monitor Wh usage to be more exact so a shunt / watt meter incorparated. DOD of 80 % or 90% for best cycle life butthen again once one gets to a certain age the battery cycle life will out last the human one. 80% DOD a typical range would be 3v - 3.35v approx. & 90% 2.8v - 3.4/45v.
December 8, 20223 yr electric cars are now a consumer product so when the warranty ends so will the life of the car be over as parts like on a 10 year old phone will be obsolete. No, cars are different since there is far more money in them than in phones and e-bikes. There will always be someone making the necessary parts simply because they will be able to make good money doing it. That's why you can buy excellent electric conversions of any very old ic car, and why WeBuyAnyCar are still eager to give me almost £20 k for my five year old Leaf that only cost just over £25k. .

December 8, 20223 yr Try Stax electrostatic "earspeakers". They're sublime (and reassuringly expensive). I'm too scared, in case I like them - audiophilia is an airborne, easily transmissible financially crippling disease. Edited December 8, 20223 yr by guerney

December 8, 20223 yr 3rd party's wont be able to make the parts as everything will be serialized so only the manufacture will be able to make them and can charge what they like or just stop making them. No not parts. Like electrifying old ic cars, swapping the whole motor etc, rather like fitting a motor kit to a bicycle. E-cars are so expensive the cost of drive motor and controller replacement is peanuts. That bypasses all manufacturers blocking. Then if neessary SVA to get on road approval as a one off and back on the road. .

December 8, 20223 yr With the differing chemistry one has to remember the series count differs. For LFP 24v becomes 8s & not 7s. 36v becomes 12s & not 10s. 44v becomes 14s & not 12s . 48v becomes 16s & not 13s. Though if one was using cells like the 32700 one could technically use 15 cells in series for an exact 48v nominal. LFP is still a lithium battery except the chem is safer and less dense pers cell size, LFP is lithum ferrous phospate . Like other chems they can short circuit but the density and any thermal runaway means thay won't catch fire. Like any other chem one still needs to equip the pack with a bms for charge/discharge. I recall you mentioned a muse about attaching a Carry Freedom bike trailer to a Citroen Ami - there aren't many images of the chassis, but at 45 seconds, it looks as though there are solid connection points: https://www.youtube.com/watch?v=1YJ9NAMOTJ4:45

December 8, 20223 yr ...top lolly for a worthless bike... lol. I think that's hysterical, but true! You said we are using the same hymn sheet but that isn't the case in many respects. My home is deliberately as minimal as it could be, bought 55 years ago for entirely green reasons when I could have bought anything far larger. Ditto. Maybe I'm late to the party, but my "holiday home" was bought as a write-off and rebuilt/renovated to be as eco as it could be... it is far "greener" than a modern build: oak and lime circa 1850, it's naturally warm, and I'll retire (properly) and likely die in it. I don't think we do have different visions of the future... just different interpretations of how to deal with it.
December 8, 20223 yr One would chang lvc & hvc, typically for 80% DOD for a 36v set up would be 33.6v & 40.2 v. 90% DOD approx. 36v & 41v . Would connecting four of these in series and stepping up to 42V, be a bad idea? Otherwise 25.74kg is a tad heavy... https://www.fogstar.co.uk/collections/lifepo4/products/eve-lifepo4-105ah-prismatic-cell https://www.aliexpress.com/item/4001275726762.html?spm= Edited December 8, 20223 yr by guerney

Your 20A controller would need >800W, meaning the current needing to go into the booster would be >60A for a 12V battery. I think that booster is rated at 40A max. Better to have a 24V system.
December 8, 20223 yr That is why they are a good thing overall and why WheezyRider was wrong in this post to say they are just as bad numerically. .
