If the power armor were the full body armor of the knight, then the kinetic skeleton would be an infantry's chainmail.
The entire mass was less than ten kgs. The supermolecular polyethylene could guard 7-12 rounds of point-blank shots from a 7.62 mm assault. If it were an assault rifle from the modern world, it would not even make a dent in the armor.
Afer equipping, the maximum weight carried by a single soldier would increase to 300 kilograms.
The power source was two pieces of battery the size of a fist and was placed above the pelvis area. After a complete charge, it would allow the equipped person to run at a speed of 12 km/hour carrying the 300 kilograms for one hour. Or, it could operate in normal combat conditions for 12 hours. The power could be charged through solar cells, or it could instantly be replenished with crystals.
