lipo management ??

being very new to the lipo scene(5s 5000mah),and not being able to run my lipo's as much as i'd like ,would having a gadget like this benefit in helping me manage my battery's life between running???

I'm kinda in the dark about proper lipo storage(sometimes 2 or 3 months) i know my Hyperion 0610 doesnt discharge but i also have the Hyperion 5i with discharge(1a max discharge rate)could i use that for discharging and getting battery ready for storage ??....i hope I'm making some sorts of sense ...LOL...
thanks for any advice or help on these noob questions
