Rechargeable batteries

Batteries are the #1 cause for issues. We use rechargeable ones solely to rule out any issues. Most people do not have a ton of batteries lying around so we recommend using a charger. With many devices out there around the world, we cannot guarantee the best store bought battery combo. 

What we use, everyday in all our devices are these:

Batteries:

Charger:

This is the combo we use and ensures we always have a fresh stock of batts.
