Yeah - with the suit that was depicted I can't see it getting more than a few hours, at most, of 'assist' for one joint (based on RW use of battery power tools). Combining the latest claims I've seen of Li type battery energy density (upwards of 5 kWh/kg) and 'super' capacitor type power density (kW/kg), one can see such a thing operating an entire suit for laptop times 
Well, existing tech for energy density and power density does exist (for bulkier powered exoskeletons) - but overcoming their thermal issues (etc.
) is a whole 'nother story! Can see early TLs using the equivalent of a diesel engine strapped to a power assisted 'suit', and there is always radiated power (which opens up fun RP aspects - ala disrupting the 'power source')...
IMTU (CT days), I've always liked to think of lower (non-fusion) TL powered armour and cargo assist suits as relying on stored power, recharged, in part, by leaching some of the users power (motion) - thus affecting Endurance.
