You can get a Quantum Telemetry device to use a fuel gage. That way you can watch your pack voltage as well as the cell voltage in the pack.

I'm uploading a video of mine on Youtube right now. It will be up in a bit.

Here is the link.

You need the receiver and a transmitter. You only need one transmitter as you clip them to the battery when you change batteries so you don't need to hard mount it in your truck or plane.

I's get the flexible antenna also.

Here is the Rx set up on my Tx. I have a 1,300mAh 3S pack set up on a 28-26 motor spinning a 8x4 prop at 10,900 RPM

Sorry for the quality but this is from a camera in movie mode. Need to get a HD vid cam!

You can see that the overall voltage drops to 10.6 well below the 11.1 I had planned for. One the bar graphs you can see the cell in the middle is weak and falling off allot faster than the other two cells. This packs only put out 726 mAh so I know it's not a good pack.

Test complete. Pack FAILED!
