Hello Everyone,
I need to design a solar based li-ion charger for a 3.7v 4000mAh li-ion battery.
The system requires that charging the battery by the panel and discharging of battery through load should happen at the same time.
How to go ahead with the design? which charger IC should I use? what should be the panel ratings?
I have no experience in this field :(...please help me out.
Thanks
