    no, it isn't worth the time, labor and cost. plus, you'd have to be an electronic/software/hardware genius to pull it off.
    battery, charger, wiring harness, evse inlet, bms, it's extremely complicated.

    a few certified geniuses around the world have added extra batteries and a plug, the work is amazing, but extremely dangerous in the wrong hands.

    I'm not concerned or interested in converting from non plug in to fill plug in capabilities, just the battery swap. have you seen one in person ?

    seen what, a plug in battery, or a swap?

    first of all, there are two plug in batteries. 4.4kwh (pip) and 8.8kwh (prime)

    the pip battery is almost 4 times as large as a nimh ptius battery, and much heavier. so you would have to do some serious structural mods.

    and you would still have to hijack the bms and associated parts. it may not even be the same inverter, idk.
    lastly, if you can't plug it in, it will just be a boat anchor, since it takes the downside of a mountain to charge it.
    have you considered the new aftermarket lithium battery?

    1) plug in battery (4kw lithium) swapped into a non plug in 3rd gen
    2) the 3rd gen battery (lithium)
    3) I'm fine with that
    4) ditto 3
    5) idk either, which is why I'm asking.
    6) there are several times during our daily driving that the 1.5kw hv battery wastes energy it can't hold (limited capacity) by spinning the ice. I want the larger capacity lithium battery to capture that regen and use it. that's kind of the point of regen, to store momentum a energy instead of venting it to atmosphere :)
    7) yes I have. I'm exploring all the options, and looking for reasons/problems/issues with each method at this point.

    this shows me that lithium packs are available and have much larger capacities, that is my goal.


    my current 1.5kv hv battery is good for around 1.5 miles before the ice kicks on, but that's testing at 15-20 mph , I haven't found a suitable test route to compare to the video results

    i have only seen mine, it is large and heavy. takes up the whole hatch below decks.

    i have not seen anyone attempt this, but it seems like overkill.

    lol yes all of those are correct, including overkill

    there’s a feller here that already created a pack that you plug in and not have to remove individual cells and replace them.
