    If there was a longer likely market period for these replacement batteries, I'd be tempted to build an LTO version that would last a number of replacement vehicles .... but they'd all have to be the same model ..... gen 2 is getting a tad long in the tooth, gen 3 was a bit of a lemon, was the Gen 4 popular enough and reliable enough to be worth the effort of designing a battery that would last and genuinely improve fuel economy and performance?

    To build one for the gen 2, test and prove any claims, with such a limited market, the cost per unit would be prohibitive ...... but maybe as a longer range unit for Gen 2 transplants into other vehicles ......

    It's likely worth it. People are still driving the first generation Prius...
    Some batteries will last longer than others. Only time will tell.
    I think eventually, each version will get less popular, and the need for the batteries will lessen.
    As parts for other car have.

    There are more and more hybrid and electric vehicles, so the cost will eventually go down.

    You have to use in order to test anything.

    I use my V3 GT in a climate that is very hot most of the year and in the winter gets below freezing.

    I have zero issues during this use and it can be called a test and passed.

    Me driving around and using my Prius with the OEM power inverter is a test and currently the testing is in year 15 and I am testing software version J0V

    I bash on people and take their posts for quotes, and I’m always right!!!

    Keep in mind theses are the People who bought the lithium and soother, now they got suckered into the salt pack hook line and sinker. You can’t invest into something and be in denial. It’s like buying a company stock and talking it up when the stock price has been trending down. Now they’re just the water carrier!

    And LTO was built for the turd gen before. On paper it was going to work but it failed. I’m waiting for solid state in 2027. Think Mendel or bisco said that Toyota’s fantasy!

    Can you supply a link to the LTO battery failure? I was building one for my Prius, but some a*hole burnt our workshop to the ground and that battery pack, the other 50 something cells , the i Tech back seat and rear interior panels .... the Prius would have been in there as well, but I needed the space to put my motorhome in so I could change the oil .... so that got burnt to ground as well .....

    At least it proved LTO cells don't burn, they lost all there blue plastic wrappers, popped their burst plugs and some of the outside aluminium of the cyl cell melted, but that was it.

    I know, so why do you keep doing it?

    So, sodium ion would suffer from the rapid recharge on regen, the discharge wouldn't be a problem. The way around that might be to use enough cells to handle the voltage spikes from regen. 6 cells x Sodium ion cells would have a full voltage of 4.0v to 4.3v, depending on the chemical make up. The nom. voltage helps to determine this, hard carbon have a nom.3.1v, Prussian Blue have a nom. 3.25v, the higher nom. voltage, the high max charge voltage.

    Using the common solid carbon as a base, 6 cells would give a max voltage of 24v, so a head clearance of 6v over normal peak NiMh voltage.

    Then, the 6 cells need to be balanced and that evened out across the whole 6 x 14 cells = 84 cells.

    Gotta a job I have to go and sort on a house boat, be back this afternoon
