SUMMARY:🔋 Beginner Soldering: Li-Ion Battery Pack
DESCRIPTION:Make a rechargeable battery pack for your LoRa node\, a microcontroller such as an ESP32 or Pi Pico\, or anything that runs on 3–3.7 Volts. Perfect for folks who’ve never soldered before! \nTo complete this project you’ll need to buy a li-ion battery pack kit for $3.99. Here’s what’s in the kit! \n• TP4056 charge controller board\n• 18650 battery holder w/ attached wires\n• PH2.5 plug w/ attached wires\n• 1/8″ heat shrink tubing (1.5″ long)\n• 1/2″ heat shrink tubing (1″ long) \nYou’ll also need a lithium-ion 18650 battery\, available separately. \nRegister\nComing soon!
