Hi! I have a solar panel connected to the Particle’s Vin pin and a Lipo battery connected to my Li+ pin. My solar panel is a 5.6W,6V panel and my battery is a 3.7V 10000 mah battery. How do I use the setChargeVoltage command? I couldnt find any information about it in the Documentation. I believe it sets the minimum operating voltage for the solar panel. What should I set this voltage to?
