My robot is based on a rc rock crawler so it can climb up/down stairs and motors take lot of power, ip camera(foscam)power hungry and ez not so much(as long as servos are not powered off it). Ez monitors all voltage,gas, room temp and thinking of putting temp on batteries(to be safe) so if motor/camera batteries dies before making it back to charger i can still monitor what is going on till i get home and put on charging dock
