want to see where this goes. I tried a while ago to design a circuit which needed a mppt circuit, and i would have prefered not using a lt3692 which is 6€ per chip (very expensive if you also count shipment. Still, i couldnt find a datasheet for the chip you use (404 error, it might be because maintenace of the page... It was in chinese and couldnt understand a thing, and also i couldnt find the chip in the "common" places where i buy electronics

and the idea of using a LiFePo4 batery is also a really good idea... Better than using a low quindiscent current regulator with 3.7v bateries

Hi, thank you for liking and following my #LiFePO4wered/Solar1 project!
