    Pack was purchased in late 2022.

    Started throwing codes after starting car in 30-40 degree mornings early 2024, and eventually failed completely (P3000 and P0A80 that can't be cleared for more than a few minutes of driving) in late 2024.

    A lot of people here sing praises about the company's excellent support. I did not have the same experience. This was the company's response:

    Obviously I was not happy with needing to spend an additional $980 on top of the original price of the pack (which was already more expensive than OEM) to get a replacement of similar questionable reliability after only 2 years of use. This battery was heavily marketed at release to last at least 10 years (all while OEM was proven to last even 12-15 years)

    Additionally, I found the last section of instructions to be a direct contradiction to their current marketing on their website:

    I ended up following those instructions anyways and it did not fix the problem in the very least.

    Despite this battery at first being superior in terms of capacity and weight, from this experience I must strongly recommend that anyone who's looking for a cost effective battery replacement to get OEM instead of spending possibly multiples of the price of OEM in labor and "extended warranty replacements" over 10 years.

    As a bonus, here's a screenshot of how my battery looked like right before it failed:

    I would guess that the pink prius we're all familiar with had similar numbers going on in the trunk before it went poof.

    Hi Matt,

    I’m really sorry if my email upset you—that wasn’t my intention. The truth is, we’re a very small company going through a tough time financially. Over the past four years, we’ve poured everything into sodium-ion battery R&D and covering lithium warranty claims.

    Out of the $900 out-of-warranty replacement program, $450 goes toward UPS air-shipping fees because the factory has paused freight shipments until we can settle our outstanding debts. Another $130 goes to government fees, and the rest helps us cover basic expenses like rent. It means that I still have to pay factory the cost of the battery with my own money.

    Honestly, it would have been easier to shut down the business entirely, but I’ve stayed behind because I have a responsibility to the existing customers and to the entire Prius community. I’m committed to seeing this through, even if it means carrying the debt until we can ramp up sodium-ion production and get back on solid ground. I wish you can understand the situation and help us out during this difficult time.

    If you have any other questions or concerns, please don’t hesitate to email me directly.

    Thanks for your understanding,
    Jack
