Solar charging Li ion batteries
Hi Newbie here.
I am attempting to build a portable back-packable solar recharger. I have a 12 volt 2.8 Amp Hr deep cell battery. I wanted to use this as a storage device to recharge 3000mAh Li-ion eighteen six fifty
batteries. Since you have been out of the USB / DC / Solar Lithium Ion/Polymer charger - v1.0 id 390 for awhile, I was wondering if the USB/DC Lithium Polymer battery charger 5-12V - 3.7/4.2v cells
ID: 280 would work? I intend to use your Large 6V 3.4W Solar panel - 3.4 Watt id 500 solar panel.
Any input or help would and be greatly appreciated.
Thank you for your time.
