I've just watched (3) separate videos that supposedly show how to update the EG4-LL V2 battery.
One of them the title said EG4-LL but in the video it was actually a LiFePower4 battery. Doesn't apply to me.
All (3) of these videos showed a different cable being used.
The cables used in the videos were as follows:
USB to RJ45
Serial to RJ45
USB to Serial with a Serial to RJ45 patch cable.


What is the correct cable I should be using for the EG4-LL V2 battery?
