Hi there, I got like 47 solar cells with each one output 1v and 0.08A but I need a solar panel that can output 12V 2Amp to charge 3 x 18650 battery and power up my arduino. I don't want to waste my money on buying a new solar panel so I came up with this schematic. Is it okay to use this kind of met…

A TP4056 module charges one or two 18650 cells in parallel from 5V.
