I have a dynamo hub and ewerk dc converter. I would like to charge a battery pack with a solar panel too.
Can I combine the 2 systems with a USB/DC Lithium Polymer battery charger 5-12V - 3.7/4.2v cells or Do I need USB / DC / Solar Lithium Ion/Polymer charger too?
A possible assemby, I feed the Lithium Polymer battery charger 5-12V with the Ewerk and the solar panel feed the solar lithium polymer charger. The chargers feed the same lithium battery pack. One output, from the battery out I feed a boost dc dc regulator to 5 V.
Is it possible? Is this an efficient system?
Thank you very much.
