I'm not sure if I'm helping or further confusing things, but in October of last year,
@Hopper Labs posted this:
I could be reading this wrong, but I took this to mean that the new GHB3 would be a higher spec unit that would out-perform the GHB2. I thought this mainly because a few weeks later, this was posted:
If I'm not mistaken, this was in reference to the new batch of batteries everyone has been waiting on.
So, to hear that the new batteries are GHB3's is where I think the confusion sets in. Given what's happened in the past ~9 months with Hopper Labs and the world at large, I personally just assumed they weren't able to overcome the barrier of the capital required to develop/produce the new cell, but maybe they were?
