DIY 9V Rechargeable Lithium-Ion Battery | 9V Rechargeable Battery

DIY 9V Rechargeable Lithium-Ion Battery | 9V Rechargeable Battery from Li-Ion Cells. I had many 9V batteries that got ruined after just one use because they couldn’t be recharged. So, I decided to take a broken battery and convert it into a rechargeable one that can be used repeatedly. In this project, I used a powerful and long-lasting 3.7V lithium iron phosphate (LiFePO4) battery for safety and durability. To make the battery output a stable 9 volts, I installed a small voltage booster module. For charging, I integrated a modern USB Type-C charging module, making it easy and convenient to recharge this battery with common chargers. This DIY rechargeable 9V battery is cost-effective, eco-friendly, and perfect for powering your electronics multiple times without the need to throw away old batteries. Materials used: 1. 3.7V LiFePO4 rechargeable battery 2. USB Type-C charging module With Voltage booster to 9V 3. Old 9V battery case (for the connector and casing) Safety tip: Always handle lithium batteries carefully and follow proper charging protocols.
