Gen.2 Price of HYBRID batterie$ are thru the roof=What are the future options?

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.
