As much as I like your product, your message feels a bit too close to marketing spam in my book and I'd rather not have the HN comment section becoming full of such posts.

Keep up the good work though!

We're trying to get the word out around people interested in batteries, that's why I kept it as light as possible, just so that people can learn about it and see if they're interested! :)

IMHO posts like this one are too much, but when you do it like that[0] instead then it's OK to me.

For the record I vouched for your post above anyway, but if you keep doing that you'll likely get shadow-banned for spam so I think you really shouldn't be too heavy handed on self-promotion.

I agree. I think it’s the ‘if you’re interested in …, check out …’ pattern that sets off many spam detectors — including the one built into my brain. Without that, it’s already more palatable.

This looks really neat, I'm curious if you know if it's possible to get a UN and UL certified battery for some of the upcoming regulations requiring that in certain states, given that someone can open it up and swap out the cells?

We are in the process of UL-certifying it with the cells that we ship it with, then if you replace the cells, I guess the certification is not valid anymore, but if you choose good quality cells you should be quite reassured to know that the whole battery (except your new cells) has been certified, and that the casing is fireproof!
