I am certain in the previous thread that Jim had 90% decided to go with the red JST plugs. I imagine
the battery compartment is likely to be sized so as to hold a 9.6V NiCd pack. Also, no charging port. Battery life is expected to be astounding, depending on mAh of the battery. DAYS are possible with the right pack.
I'm certainly not trying to speak for Jim, I just know how hard it is to wait until the next afternoon/evening for an answer.
