Good day to all members.
While there's a similar thread here not a definite answer on it.
I want to power an Rpi4 of the grid that will run with a 2 series 18650 through a power management board.
Now in my inventory i have a 10w polycrystaline solar panel with 18-20v output. While i tried and fried a TP5100 charger IC (inpu5-15v) before a hx-2s-jh20 BMS and the batteries.
I was thinking to use a CN3722 MPPT if fits for the purpose or a pull down between the solar panel and a TP5100 to lower the input voltage
Has anyone a practical experience on the matter to share?
