I just started a new career (after my old one developed a minor bug that I didn't want to work through) with Kerbal Construction Time and TAC-LS. On my first Mun landing Val didn't have enough dV to make orbit again, but she had lots of supplies, so she settled in to wait for the rescue ship to be built. Then she discovered that she didn't have enough battery power to make it though the long Munar night. So she disconnected the pod battery, only turning it on for a few seconds every 115 minutes to clean the air and then turning it off again. I lost track of how many times she had to wake up to briefly power up the LS during that long, cold Munar night. The rescue drone ship, with extra boosters and batteries, is currently rolling out to the pad.
