Wondering if i might ask those of you with far superior electrical knowledge than me (thats most of you lol) a question...
I'm building a hex for aerial photography and have been planning a dual battery in parallel for redundancy.
We're using the APM2.6 and would like to use it's PM so i can monitor the voltage through the GCS.
Trouble is, that PM is limited to 70 amps (from memory) and the ESCs will draw up to 120.
So i've thought that instead of making a 3 plug parallel harness i could make up a 4 plug and run 2 systems. One side for the motors (direct wired to the parallel harness) and the other side for accessories like gimbal et al (wired from the APM PM which runs back to the parallel harness).
My question is in a couple parts:
-am i introducing a short in the system?
-will i get accurate voltage readings?
- is there some quantum effect that i'm missing (lol- but i do think of electricity like water and am aware that it not always the case))
- am i just crazy?
- your thoughts?
Sorry for the noob question; i just don't want to wire this up and watch my first effort at this smoke up a couple grand and weeks of my spare time.
I've attached my planning schematic (i stand ready to be flamed for my horrid lack of electrical drawing skills!). You can see the wiring harness i plan above the batteries. The APM PM is on the Right (top) system, and the motors/ESC are on the left (bottom). The two power distribution boards before the gimbal et al and the ESCs are those cheap ask ones from HK which are supposedly good for 160 amps each.
Thanks for any and all advice,
