Yes, I think a few days worth of advance planning would do me much good. I typically think of a video idea in Friday night coming hoe from swim team, and then directly film it. Luckily, this Friday is holiday so I can get battery on Thursday, plan out everything, and get it going on Sunday. I have been investigating the best way to change the battery recently (it arrives Thursday,) and plan on connecting a power supply to the 2 terminals, then desolder the battery, and solder in the new one. Plug the meter in (without sticking my fingers into the socket) and powering it on before removing the supply. Any comments would be appreciated.
