Lipo voltage question
I'm trying to determin how much juice I have left in m packs. I run 2 6s 4000mah packs in series and my vbar software shows after a 5min flight that I currently have 5.717 V and my min voltage is 5.609 V. Can anyone explain to me what this means and how much power is left in my packs.

You need one of these. I like this kind but there are cheaper ones. And also see how much you put back using your charger.. never put back more than 80%

The best measure of how much is left is to charge them and note how much you put back in.
If you flew for 5 minutes and charged the pack with 2000mAh, that is 400mAh/minute. A 4000mAh pack can safely give you 3200mAh. That is an 8 minute flight. |

To know how much is left, use the method WC is descibing. Charge your packs after your flight and see what the charger puts back in them. Don't use more than 80% of your pack.
