TCS question

[ReV:-O]

so it is pretty much the same as setting the TCS to 60% then?

if my batteries are fully charged but i cannot run them, could i use the TCS, set at 60% (or store mode), to DISCHARGE my lipos to a save storing voltage?

is 3.7v the best storing voltage? could 3.8~3.9v also be ok?

many many thanks
