Hi, I have bought a new Vantage B6s+ Advanced Balance Charger today from RCBazaar Pune(Great store!  , though it has not been setup fully yet). While charging or discharging batteries I noticed some number in the bottom right.
Can anyone tell me what that number indicates?   
I have attached a pic, have a look at it. Your help would be highly appreciated. 

Energy in mah...going in while charging and utilized while discharging

Thanks girishsarwal.
