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.

Great Kcharuso, but how did you measure that?
i bought one off my friend as it did not charged thinking i can fix it. i couldn't so i took it apart and measured stright from the terminals going into the control board from battery. however, terminals from the control board to the three sockets to the drone read zero volt. the board was bad and there is no way of fixing it. ill post pictures tomorrow to clearify the issue.

I tried testing the middle and the side terminal, but got no reading.

there are black&red wire from the battery going into the board and out to the connector where it will interface with the drone. i haven't take any reading from the connector itself. i just went straight to the lead power wires.

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.

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.

Gee wiz, didn’t mean to offend so easily. Somebody kept asking how to check voltage and was worried about shorting something out. Pictures dud not help with that. Just tried to help. Will refrain in future. Too many weirdos on here. Happy New Year.

As a follow up, I did contact Go Pro about the use of a multimeter and they sent me a MSDS sheet on the battery. It didn't help much but there was a line in the sheet that warned about the use of a multimeter.

If you know anything about multimeters the current function creates a way for current to flow thru the meter and if the lead is placed across two opposite poles of a lipo it just like a dead short. Nice warning, is very true.
