LiPo batteries to run servo motor

I have a project where I wish to run a servo motor occasionally from an Arduino and powered by a solar cell charging a LiPo battery.

The issue seems to be that the Arduino and especially the servo want more than 3.77 volts from the battery.

So… Can I use two solar cells and charge two LiPo batteries in series to get 7.54 volts? Does this require two Solar Buddy’s?

Thanks,

Peter

Its not a good idea to charge 2 different lipos at the same. Unless they specifically matched. Why not use one 7.2 pack? Just calls for rethinking of the solar panels.
