Seeking creative ideas

[chrisblessing]

I posted a week or so ago that I thought I had a failed cell among the 4 120Ah cells in my DIY battery. In my haste I ordered a single replacement. Only after returning home from our long trip did I determine that the BMS had failed. I now have a working battery again (with new BMS), as well as a single 3.2 cell in the mail.

I'm wondering what possible uses there might be for this one single cell. Thanks. Creativity is welcome.

An outdoor solar LED area light mounted too far away from any other power... Solar x-mas lights? A solar cellphone charger (or even without solar, just to charge portable devices when away from land power)?

Thanks. I'm not sure of the voltage requirements, but that's a thought. I did though find that there are low power boost converters that would make that work.
