I messed up…

I finally made my way out of the lost river and into the ILZ today. I wasn’t sure what to bring so I just piloted my cyclops down to where it first opens up into the large cavern. I hopped in my prawn suit, went exploring, found the lava castle, finished up everything there, and then upon returning to my cyclops I realized I forgot to remove the power cells. I got in and checked the power. 1%. Luckily I have the thermal plant upgrade
