Only 2.9Kg for 24Ah. :) Awesome. Not that weight matters at this stage!
I think I will end up with 4 batteries eventually:
This bad boy to run the feet and dome drives, 2-3-2 motors, and power the servos.
2 x 12Ah 5v Powerbank USB supplies, one for the dome and one for the droid to power all the Arduino and the Teeces.
Finally I'd like to add a 10Ah 12v Lipo battery for the audio so that he can still do the lights and sounds when the main battery is dead, but that one can wait. :)
I am also intending to rig up the SLA batteries i have as a stand supply to save the driving charge. :)
Also James is on the case. Can you tell what it is yet?
Trick question really, it's the first custom stud, it's a part of the 2-3-2 shoulder mech, not a pet name for James. :) Thanks for doing these dude, will be much better, i have thought about how to improve those so many times. :)
