Hey @darkflame! Haven't heard of such batteries before, thanks for pointing that out!
As a matter of interest, there's a tribe on the steem platform known as Build-it that accommodates all DIY, How-to tutorials, and lifehacks respectively.
That being said, your DIY/how-to tutorials get rewarded with the tribe's token known as Build upon posting via our website or at least one of the recommended tags; #diy, #how-to, #build-it, #build, and #doityourself. Our curation account @build-it.curator will curate every valid and reasonable posts/projects.
Chat with us on our discord and telegram channels Discord, Telegram
