Multimeter upgrade or how to transfer any device to lithium batteries🔋⚡️(Quick and Easy, #20)
Hi! Today, we will share our option how quickly and easily to improve any device by replacing the batteries (galvanic cell) with a lithium battery at home. This enhancement will allow you to charge your device via micro USB.
An example of this upgrade was our old but time-tested multimeter. Previously, our author did similar work with other devices that have been working accurately and uninterrupted for a long time.
For such modernization we needed:
• Lithium battery charging module
• Step up module
• Lipo battery (we used it from a small copter)
• A device that needs an upgrade 😉
