> Your statement of "lithium ion packs are far more dangerous than gas stoves or general use of electricity" seems a bit far fetched.

I wish. I've installed distribution panels and gas gear and none of that comes close to working on a sizeable Lithium Ion pack in terms of risk.

If you don't believe me that is something I can not help but there are other commenters in this thread who back that up, surely the people that actually did this stuff have some relevant experience?

The stats are what they are because of the relative distribution of e-bikes vs gas stoves and such. What should worry you is that the number of e-bikes is still relatively low vs the number of gas stoves.

As for sharing the document, I'd love to but there is no email address visible in your profile, could you supply one please?

As for the statement, as a professional I do tend to believe other professionals. Ultimately the statistics don't lie: lithium ion related fires are a minority of current household causes. To your point, that may change over time particularly where larger installations (e-bikes, solar system batteries) are involved. I'll pitch that the regulatory regime is more than capable of catching up and enforcing change if the degree of risk starts to go up. We already see fire departments commenting on it, so it won't be long before we start seeing guidelines and restrictions on battery sizes within homes.

Ok.

I haven't published it yet, and will probably do so in the near future so if you read HN regularly you'll see it sooner or later.

Looking forward to it!

I have far more lithium batteries on my desk than I do gas appliances on my entire property.

I'm not an outlier either. Most of us carry at least one fragile lithium polymer battery on our person at all times.

I understand that larger packs like those on my bicycle are more energetic, but I'm still not convinced that it is more dangerous than something as mundane as the grill on my patio, and the stats seem to back this up.

The point is, though, that both are pretty safe as long as some standard safety protocols are followed. Should you be allowed to spot weld 18650s on your kitchen counter? no. But you also shouldn't be building experimental grills in your living room either, or playing with gasoline.

Hi, could you please share your notes with me? I've put my email in my profile.

yes, of course, I will send it.

Edit: sent! should be in your inbox, happy reading.
