If you do not want to run Aux2Bat for the Technician boost, then a better way to combat weapon drain would be to run EptW3 with Damage Control Engineers.
Consider other power boosting measures such as:
Maco shield's power conduit link
Borg Cutting Beam + Assimilated Module weapon amplifier
Experimental Beam Array
DEM and Marion Frances Dulmur's mini Nadion Inversion
Liberal use of weapon batteries
