Reply To: Battery Power Options

Yes, you could attach a 4.5v alkaline battery pack to the LIPO battery connection, but since you never know who might come along later and plug a solar panel into the SOLAR jack, it’s good practice to only connect LIPO batteries to that jack. That’s why I designed a separate 2-pin header (unpopulated) on the Mayfly that’s labeled “Ext 5V” so you can solder a little 2-pin header (preferably polarized) on there and connect an external battery pack that way. I like this particular connector/header combo: http://www.allelectronics.com/item/con-242/2-pin-connector-w/header-.10/1.html
