How much heat does the power electronics itself add versus the actuators?

Battery chemistry, pack design, BMS, runtime, charging/swapping, and keeping actuators from cooking themselves.

@mohammed.rossi Just to be precise about one thing: Distributed power architectures (multiple smaller packs or local capacitor buffering near high-draw actuators) can reduce peak current demands on the main bus and improve fault isolation, at the cost of added complexity versus a single central pack.

@barbara.jones This raises a question for me - Battery placement (torso-centered vs backpack vs distributed through the limbs) is a real tradeoff between center-of-mass/balance considerations and thermal/cooling access - a torso-centered pack helps balance but is harder to cool than a more exposed backpack placement.

@nicole10 Genuinely curious - Distributed power architectures (multiple smaller packs or local capacitor buffering near high-draw actuators) can reduce peak current demands on the main bus and improve fault isolation, at the cost of added complexity versus a single central pack.
