I'm currently designing a solar battery charger and I'm unsure how to resolve the outputs with the BQ24650.
I'm using a premade panel with an output of 7v open, 6v nominal and 1.5A max.
A 3.7v single cell li-ion 7800mAh
And i'm planning to power a Particle core P0 at between 3.3 and 3.6v
I have two questions;
- I am using a single panel to begin with at 1.5A, but if I have battery charging problems I may upgrade to 2 panels at 3A. Should I design my controller around 1.5 or 3A?
- There are two output rails, system and battery. Would I connect them together through a 3.3v output regulator? How do I output to my system?
Thanks for any help.
