I’m a beginner building battery-powered synthesizer around an Artemis Nano and Class D audio amplifier. I’m struggling to understand what options I have for using the Artemis Nano to power and charge the system. My initial thought was to Lithium Ion Battery - 18650 Cell (2600mAh)'s in battery holders but I’m struggling to estimate charging time and how long they’d power the system for. I need a certain amount of run time for a theater production and to think about charge time between shows.

Are these batteries compatible with the charger on the Artemis nano? How many could I use? What resources should I use to learn about charge time and estimating consumption?

Thanks in advance for your help!

Artemis Nano has an On-board Lipo battery charger. Lipo is different from Li-ion 18650.

Thanks for replying. That’s what I thought, but the Hookup Guide for the Nano here: [https://learn.sparkfun.com/tutorials/ho … temis-nano](https://learn.sparkfun.com/tutorials/hookup-guide-for-the-sparkfun-redboard-artemis-nano) also says, “Any one of our LiPo batteries with work great with the Nano” and links here: [https://www.sparkfun.com/categories/54](https://www.sparkfun.com/categories/54). I only see one LiPo battery there ([https://www.sparkfun.com/products/13852](https://www.sparkfun.com/products/13852)) which is on backorder.

So, if I’m looking at using the on-board charger, are there any good recommendations for larger capacity batteries I could use to run this system? Or, am I likely looking at a different kind of battery charger and solution?
