Tips for specification of an optimum power source when using nano**DRIVE** units.

## Power Supply

The nano**DRIVE** 4LPi units can receive power from a wide type of power sources. Commonly used are:

- Batteries (Li-Ion, Li-Po, etc).
- Uni-directional Power Supplies (standard bench power supplies, tethers, etc).
- Bi-directional Power Supplies.

:::hint{type="danger"}
When using uni-directional power supplies, **AFW must be disabled **to prevent damage to the power source or ESC from regenerative power.
