You know that problem: you come back from a flight session and have to put all your batterys into storage mode. This normally takes hours and is very enoying.

With the Aokoda CellMeter 8 it only takes about 15 minutes for each battery to be set on storage mode. It uses 3 light bulbs which discharge the lipo. I personally use this device every day I fly and never had any problems. Its very compact and you even can take it on the field since you don't need a power plug. It's also usefull to check your battery voltage.

The Aokoda CellMeter 8 costs about 16$ and can safe you a lot of time.
