My own design  of  a LiPo tray to keep my LiPo batteries organized. 

and with the Full/Empty label you can easy see witch lipo is full or empty.

i set the main lead as a indicator. main lead on the empty side for empty and vise versa.

LiPo size.

fits for all types of lipo's with the size of (40mm x 35mm x 54mm or longer)
