Alright, well I'm trying to get back into some fun (summer is here) as work and life slowly become more manageable. I've got some great projects in the works. Learned how to EUC and am currently spark shooting an Ecomobl M-24 presently. Great to be back!!

Well ladies and gentlemen....video update tonight. I have some very interesting news. So the exway battery appears to have a common bus between the charger input, and the main power to the ESCs.

So there are 2x pigtails that are unused that are the leads to plug into the aux pack deck plate adaptor. They have full battery voltage. (So yes, if you can get wires out of the enclosure, you can get ~50v of juice for lights, USB outlets or whatever you want to strap onto your board)

Now, here is where it gets interesting. I put my multimeter on one of the pigtails after thrashing my board (battery 75%. When I plugged my charger in, I had a voltage bump that was equal in every pigtail, and equal to the XT30 charge port input. So, this..in my monkey brain, confirms a common power rail between the ESCs, the pigtails and the charge port.

So, for my buddy @Michael Hurdle Production Studio yup, your board definitely is getting drained from the charger as the charger is sucking power off the main power bus. This is good in a way too, because the charger is a dumb charger, just supplying current and voltage until the main bus reads 50+ Volts. It also means as long as you voltage regulate and keep it below 1kw, theoretically you can recharge the main pack using the pigtails (how the Aux pack works). Now, this is still speculation. I probably violated all my warranties by doing this. So don't do it. Unless, you're like me and love making expensive paperweights with a small firework show.....
