What are voltage and current limitations for FP4 battery charge, please?
I would like to commercialize small PV panels with USB output of 6V 2A max, but is it safe to do it on a daily basis?
Moreover, I have a USB-C computer charger of 20V and I have tried it once to charge very quickly my FP4.
And it has worked.
What are implications please?
Finally, I know our smartphone batteries should remain between 10% and 90% charge levels (DoD).
Any app’ or feature to recommend, to keep it this way please? I have set up the Fairphone warning for low charge, but I would like to stop charge at night at 90%.
