Off-Grid Solar Battery Calculator
So if you have 12V LiFePO4 battery bank you''d use a voltage of 12.8V. Battery bank nameplate Ah = Battery bank nameplate Wh / Battery bank voltage Battery bank nameplate Ah = 10,867.5 Wh / 12.8 V Battery bank nameplate Ah = 849.02 Ah. So you need a battery bank with an amp hour capacity of at least 849Ah.
How to know how many LEDs can be used at a given voltage
Typical ranges go from 1.8 to 3.3. Based on what you describe seems like you have something lower than 3 volts (since it does turn with 1 battery). You can see in the following image I have a 3 volt-drop LED, if I power it with a 6V battery I have both LEDs light up. As I measure the voltage between the LEDs I read 3 Volts, as expected. Hope ...
