The following values/power point for different sizes are calculated from the weapon damages with the base weapons being 25% efficient and one shot/20 seconds and the improved versions as 50% efficient to get the extra rof with same energy.

Power Cell energy
TL 11: REF 10, that is 10s time the energy of corresponding TNT TNT is 4184kJ/kg. Thus the energy is 4184kJ/kg*10=41840kJ/kg (42mj) That is 41840kJ/3600 seconds=11.6 kwh. Each TL seems to be a 4x step according to the REF numbers and the blaster/laser design in pyramid 37 so: a TL 10 one is 2.9kwh/kg and TL 9 is 0.73 kwh/kg A C-cell at 227 grams is thus about 165 watt hours. Rechargeable are assumed to be half that.
So rechargeable kwh:
