also 2 ion power cells you can drain till zero and just keep em, you can use empty ones in rocket craft. some biomes dont have em, but there is plenty. Alternatively, craft and equip the thermal energy module to allow the cyclops to restore energy while in hot areas. Take them out and charge them in a powercell charger. or keep kyanite power module in cyclops and park it near heat areas now and then to recharge, does not need to be in lava zone. The Cyclops is powered by 6 powercells in the engine room. later on just farm infinite amount of ion cubes and go super power cell on cyclops. and there you go you have fresh 100% cell, keep 2 emprty power cells for double cycloops shield craft, 1 in rocket, one as cyclops module. have spare powercells, and those rubber thingy to craft cells from batteries stocked up on cyclops, once you drain batteries store em in container, if u have 2 or more pairs just make power cell from 2 empty batteries. Never build stuff on cyclops that use power, if you need build for few secs when you use, dismantle right afer, if you were in lava zone use cyclops diagnostic screen to see if u have larvas attached.
