Hi folks, first post here so sorry if I miss some standard information!
I’m looking to use a LiPo being charged by a set of solar panels (currently looking at a few of https://www.digikey.com/product-detail/en/ixys/SM531K12L/SM531K12L-ND/9990471 wired in series, though their output would be less than 12V) to run a 12V circuit. I’ve only ever dabbled in some basic Arduino and Raspberry Pi projects before, but I’ve always been a bit nervous around LiPos so could use any pointers you’ve got!
My initial thought was using SparkFun’s Sunny Buddy (https://core-electronics.com.au/sparkfun-sunny-buddy-mppt-solar-charger.html) to charge a single cell LiPo, which was then connected to some kind of voltage regulator (https://core-electronics.com.au/pololu-12v-step-up-step-down-voltage-regulator-s18v20f12.html) to step up the output from the cell to 12V.
Would this kind of a setup work? Or is there an issue with discharging from the battery while it’s being charged at the same time? Alternatively, is there any way I could rig up a way to charge a 3s LiPo using solar panels rather than charging a single cell?
