    What does the video you just linked have anything to do with what we are talking about? It doesn't matter if the battery won't blow up like a lithium ion battery...............the BMS/battery packs for the v2 and 2.5s are badly designed and the fact that the only argument against them being defective is "well they won't explode" is just insanely silly.

    The fact is Nexpower sold dangerous batteries, then immediately did a "very soft" recall on a very dangerous issue speaks a ton on possible future experiences, even if they change the BMS or battery chemistry.

    Again, this is why in some countries you need an engineering degree/license to do the stuff Jack is doing (because it IS dangerous/hazardous, including to potential consumers). You can't just go "my bad, buy my new battery and try again".

    If you look hard and long enough, you can always find someone crying and wining about something.
    NO product is perfect. That is why there are "prototypes". To find the weak points and fix them.
    They are not built like the final product, because they are TESTing them. Don't expect them to be
    built like the final product.

    When I needed a new hybrid battery, I was going to buy the OEM pack from Toyota. But the guy said
    they can't sell them over the counter any longer. At least not in Florida. I've done a lot of business with
    this dealers parts department and they have always been great with me, and price wise have been fair. NO complaints.

    So I looked elsewhere. What a pain! One place close to me said he had them in stock. He was an hour's drive
    from me so I told him I'd be their in an hour. Then he said they weren't actually "here", he'd ship it from his
    warehouse in another state. That flew up a red flag. Other places online, and ebay, all kinda flacky.

    I had read all the remarks, positive and negative, about Jack and his lithium pack. But his cost was less than everyone
    else's packs. Eventually, I decided to give it a try. If he didn't ship it in the time stated on his web page, I'd contact him
    and expect a refund, now, not weeks or months later. If he didn't, I'd call my credit card bank and tell them what's
    going on and they would get the refund for me. So I wasn't worried about that.

    I went on his web page, ordered it. It came back as "out of stock". New stock in 7-10 days I think it was.
    I said, okay, I can wait 2 weeks. The next day I received an email saying they had arrive and will be shipped soon.
    3-4 hours later I received another email with a tracking number saying it had shipped!!!
    I expected about a week from California, I'm in Florida. It came in 3 days!

    Installation was almost exactly like Jack said. Pretty straight forward. I checked the voltage of each block. All were
    within 1 tenth of a volt or less.

    On my first drive with the new lithium battery, I noticed a huge difference over the oem pack. My mpg went up. The
    distance in ev mode went up. Everything Jack said about the battery, was correct. Everything he said about installing
    it was correct. I had some issue and questions about the installation, and wanted to make sure I was doing things
    correctly because there are only connections on one side of the battery. Except for 1 block for the disconnect.
    He returned my texts very quickly. I was a happy camper!!!!

    About 4 months later he contacted me and asked me to be a tester for the new Sodium pack because it was very
    hot and super humid this past summer here. I said sure! He informed me that this is a prototype pack, not the final version.
    He said the installation might not be as straight forward as the lithium pack. And he was correct. I noted the issues
    and let him know. Overall, it was not a difficult installation.

    When I drove it for the first time, I noticed a big difference over the lithium pack. It keeps the charger longer.
    Recharges quicker. EV length is further. MPG went up about 2mpg. I was driving faster on the highway, and sportier
    in the city with the lithium, and the mpg went up about 4mpg over oem. My average in the city was 38mpg, with the Sodium,
    it's 42mpg. I can easily get 48pmg on the highway, but if I drive a little slower, I can get 50-52mpg.

    As a test prototype pack, I've only had very minor issues, if you can consider them issues. It's never overheated.
    And stays between 140-180 degrees, depending on driving conditions. The temps might be lower, I don't remember
    exactly. Unless I'm sitting in the city, then it goes up to 195 or so. It's never gotten to 200 degrees. I tried different
    ways that Jack asked me to try, to test the pack and get it to overheat, but can't.
    Only 1 block had a little lower voltage then the others. Well within tolerence, but a little low. He sent me a replacement.
    Remember, Prototype, Test Pack. This is what TESTING is for.

    I Replaced the lithium hybrid battery with Sodium battery on 19 September 2024. At 352,929 miles.
    I am at 369,768 miles now. And no problems! I'm not even trying to get higher mpg, but am getting them.
    I have NO issues whatsoever with either pack.

    Jack has been super helpful, and quick to respond to any question or concerns.
    All the negative things posted against him, he proved were incorrect. I CERTAINLY recommend him and his
    product! I am NOT an easy person to make happy when it comes to customer satisfaction. I have a very
    high standard. Jack has certainly met those standards for me!

    Some people just like to complain and will look for any reason to be miserable to make other's feel like them.
    They just like to cause trouble. Usually from a competitor. Because perhaps their product is not so good so they have to
    try to make other products look bad to try to make theirs seem better??? Buyer beware!

    I'm certain, the final Sodium pack will be a higher standard then the test packs.

    The words "May Have" and "Allegedly" don't stand up in the court of law for making accusations that something actually happened. I can't wait for the counter suit for slander and defamation of character to be filed against the likes of you and Mudder and anyone else caught up in this where we can hunt you down and dox you like dogs.

    As for the smoke and fire issues, the only things that I have seen come into the shop that exploded (literally blew up and the guy almost crashed his car getting off the freeway) were stock OEM batteries that had been neglected and many miles on them. The SINGLE case of "alleged" fire, was the Gen 2 with a melted blade with some smoke lingering in the trunk area. Out of the thousands NexPower has sold, where are the rest of these horror stories if they are that bad? Gee, all that...and the packs around it were still good in the photos. Pretty scary story there bro.

    You (and Jack possibly) clearly have no idea how "slander" laws work. I have a pack. I am a customer. My pack is in a hazardous state, which was determined by a qualified electrical technician. I'd love to post images of the blade in question (it's a doozy) but since we're throwing around legal claims, I'll hold onto those image and absolutely encourage you or Jack to "file slander charges" or whatever silly crap you are talking about.

    I'll hold onto this 15,000 mile V2 pack and also have a masters degree holding electrician on standby in case you want to take this to any court in California or the US for that matter. I hope Jack has proper proof to show these packs are safe/functional, specifically the V2 and 2.5 Nexpower Prius Gen 2 Battery Replacement. If not, this is just going to cost him/you/whomever cash and I'd love to post the entire ordeal here for people to see how Nexpower handles Criticism.

    Again, please follow up and file the required court paperwork. I don't think it's gonna pan out for you as you think, but shoot your shot, Tex.

    P.S.
    Did you just seriously threaten to Dox/leak my personal information over me telling people to stay away from Nexpower batteries because my own (and other batteries sold by them in the V2 and V2.5 Prius Gen 2 lineup) had issues?

    Do the admins of the site really allow that kind of talk? This is really just insane at this point. Wow.

    There is no "perfect" product. There are defects, it happens, welcome to life. Look at the head gasket and egr system
    of the 3rd Generation Prius.....
    So I guess EVERY Prius, every Toyota is dangerous, is terrible, and too dangerous to buy.....

    There's really one active mod here as far as I know, and it's a lot of work, and I get the impression he hasn't really got time to evaluate posts "on the merits", as it were, but does respond when something starts spiraling into being a nasty thread.

    If I remember right about the earlier thread that did end up with words from the mod (and the site owner too, as I recall), that really happened after the conversation went off into lessons on slander law and who could afford the biggest retainers and other legal biggdickery.

    :ROFLMAO::ROFLMAO::ROFLMAO: Who, the Maytag Repair man?

    Ask John (Mudder) how that turned out for him on this forum and how he had to cease and desist his slander of a business. Personal slander is going to go nowhere or BlackJimbob would have been in prison by now and that didn't happen but if a business has lost revenue stream due to unsubstantiated claims and slander about it's products and services you better hire someone better than the Maytag Man to represent you.

    Ok, I'll ask. How did that go, @mudder? We know about the temporary PriusChat ban when an earlier thread descended into legal biggdickery. Other than that, have you legally had to cease and desist anything?
