If you can turn on each diode separately using the optics you have, you can measure each diode individually and add the results. I am interested in what its actual power will be in the end.

No wonder. That pack has a voltage spec of 11.1 volts. At full charge it is likely over 12 volts. I have never had the need to even look at these before now. Glad to know they are not safe to run with laser diode drivers. I'll take you at your word, Jordan. If you have seen this more than once it is not something I would be interested in trying.
I've been following this thread with interest and I don't want to stick my nose in where it doesn't belong but I'm just wondering when they power 8 diodes in series like that I imagine they just use one big driver but how much voltage do they put to the driver and how many amps does something like that draw?Looks like they run 8 in series. This is the reason 4 are placed one way and the other 4 are rotated 180 degrees, so they can power all 8 in series, LOL

Yea I just threw 2S in there. One thing seeing is some post saying using cap or TVS that works as intended with the kinds of transients from one source like what we would expect to deal with say 2-3 li-ions in series or a bench power supply whatever may actually have the opposite effect with the very different levels you see out of these packs and the gist was that you have to calibrate it to one or the other which means that either we have multiple versions of the driver or that is handled external between the driver and 3S pack. Actually that reminds me I was looking as some very high end LED drivers over on CPF and it had a drop down for the different power source and remember 3S maybe 2S and 4S not sure if they were listed had have different cap/TVS combo or whatever than the li-ion sources. Will try to find it.
Here are a few things I just dug up again so pretty close to the trail I went down when I decided to write that warning.
