Can confirm you do not need any batteries physically connected to the x750 if you have batteries attached via the BATT input. If you are wiring the batteries yourself (save yourself the extra $25) you need to wire them in parallel. Might be smart to use protected batteries if you're wiring yourself.

I removed the battery slots on the x750 completely since space very limited and couldn't find the x708 anywhere and everything works flawlessly.
