All you need is two 3.7V batteries, a voltage booster module, a charging module and a non-usable 9V battery body. In this project, I will show you how to make the charging module very small so that it fits more comfortably inside the 9-volt battery.List of tools and parts: https://drive.google.com/file/d/1PHdGB_tjRMRojCI0Y5mBGutU1khOqClx/view?usp=sharingHome by Hotham https://soundcloud.com/hothammusic Creative Commons — Attribution 3.0 Unported — CC BY 3.0 Free Download / Stream: https://bit.ly/3qI5uDy Music promoted by Audio Library https://youtu.be/mN5qY3Xe-MI#Penguin #PenguinDIY #9V_Duracell_battery #9v_battery #rechargeable_9v_battery #rechargeable_battery #repair_9v_battery #9V_Duracell_battery Wed, 23 Sep 2026 05:23:03 GMT https://validator.w3.org/feed/docs/rss2.html PeerTube - https://piggytube.piggy-server.org https://piggytube.piggy-server.org/lazy-static/avatars/92ad7bdd-6440-4318-8535-27765d598515.png https://piggytube.piggy-server.org/videos/watch/7ff2117a-45c9-40eb-bb61-3e954b7623d9 All rights reserved, unless otherwise specified in the terms specified at https://piggytube.piggy-server.org/about and potential licenses granted by each content's rightholder.
