how many MAH does a lipo lose in 2 weeks

[blueb8llz]

so i did my test. do i have the right idea here? when my 2s 5k lipos are ran down to lvc and i plug it into my charger it reads just about 7 volts. so i charge it up 50% which is 2500 mah, the voltage reads 7.93.
so basically what imma do is occasionally check my lipos when storing for long period, when it drains down to 7 volts, then i know thats the same as when its drained to lvc. ill go plug it into the charger till it hits 7.93 volts, then i know thats close to charging it at 50% again.
now, i just needa see how long it takes for my lipos to actually drain down to 7 volts from 50% full charge. im not gonna do that anytime soon cus im still having a blast. maybe in winter is when ill do the real test.
do i have the right idea here guys??
