Great Kcharuso, but how did you measure that?
i know the pictures don't help much and I didn't expexted to but there is a valid reason i took the pictures and dissembled the battery like so.Pictures as taken do not help much. The circuit card is part of a built in balance battery charger. One contact is common or ground, usually on an end of a connector but I have never seen a need to check a Karma battery yet. One contact is the main which is the other end of the battery cells, or battery pack, in series. The other contacts are individual cells. If using a volt meter, or a meter set to DC volts, you cannot short anything out as long as you touch each test lead to only one cell at a time. Depending on charge level the full pack will read around 14-16 volts and each cell around 3.5 to 4 volts. If you read nothing you are on 2 cell leads or a cell to main lead.

Is there a chart of the contacts on the Karma battery that we can use a multimeter to check battery voltage? I would like to know the actual voltage and not just use the lights.
Do you have any steps for pulling apart the battery? With the 3DR Solo there is a procedure to pull apart the battery and replace the cells and then you can reused the battery and this is something i would like to look at doing with the Karma.Hi all.
I know this is kind of an old thread, but this might be useful for anyone else with the same question.
After thoroughly taking apart a battery, I have figured out how to test the battery with a multimeter. When facing the battery port, the whole left port is positive, the whole middle on is negative and I'm not sure what the right port is but I think it has something to do with cell voltages.
I took mine apart because it wouldn't charge. Now I'm using the plain cells for a DIY drone I made.
FYI, Taking the casing and extras off the cells drops 100 grams of weight.
