If you were supposed to get an email from the forum but didn't (e.g. to verify your account for registration), email Wes at stararmy@gmail.com or talk to me on Discord for help. Sometimes the server hits our limit of emails we can send per hour.
Haven't gotten in touch with Ira about it yet (he has given me the OK to tinker around as I see fit though so I don't imagine a battery is going to upset him).
So, it depends on the actual item, can you please edit your article and mention that. Also still need you to fix that tag, we do have an official one =)
Since it is smaller, it would still fit in anything designed to use the 20cm long power cell. I just like the look of the smaller cell than the larger looking one I designed for nepleslia.
