How can I use my 3.7Volt lithium as a 9V battery?
But don't want to use 3 of them in series.

Hi

This can be done by a small boost module like  Adjustable Boost Module SX1308 2A (botshop.co.za)

The Adjustable Boost Module SX1308 2A is a remarkable little device with several features that make it stand out:

  1. Compact Size: Despite its small form factor, this module packs a punch. It’s designed for portability and convenience.
  2. Output Voltage Range: The module can generate output voltages ranging from 2V up to 28V. This flexibility makes it suitable for various applications.
  3. Built-in Protections:
    • Short Circuit Protection: The module guards against short circuits, preventing damage to itself or connected components.
    • Overheating Protection: It also has safeguards to prevent overheating during operation.
  4. Adjustable Output Voltage:
    • The module features a 10K potentiometer that allows you to fine-tune the output voltage.
    • To set it up, connect the module to a power source (between 2V and 24V), measure the output, and adjust the potentiometer until you achieve the desired voltage.
    • Note that you might need to turn the potentiometer a few times before seeing a change in the output voltage.
    • The 2A is a max short circuit for a 1Sec before it will run into problems.
