Hi! Total noob over here. I was hoping to eventually build a portable synth with my daisy. I’m learning a lot from this forum and various internet sources but one piece of the puzzle I haven’t seen anywhere is batteries. What would be a good rechargeable battery to use with the Daisy that won’t break the bank?
Just use a standard 18650 lithium cell (as in vaping products, etc) and a charger/boost convertor such as this
If you need it for long periods then you’ll need to use more cells SAFELY, i.e. not just wire them all in parallel, but try it for one first and it should last several hours. If your MIDI keyboard uses too much power then use another cell and boost convertor for that.
