You can somewhat see it in the 2nd pic, with the FC off, but will upload a closer shot (done, photos 4 and 5)
In summary Ground wire is the only one "holding" the connection saver in place right now going up to the XT60, with another 14AWG ground wire feeding into the Ground of OmniF4 - in hindsight it probably doesn't need to be this big as I'm not feeding much via the OmniF4, most everything goes through the PDB ground. VCC/Positive from the XT60 battery feed comes down through the rubber connection saver and goes to the VCC on the resistor shunt, then the Return to feed power goes back and slips between the rubber and the PDB and connects to the PDB itself, completing the circuit.
That's a creative way to get the benefits of both, nicely done. I've got a couple questions: Is that thick of wire gauge necessary? Are you having any issues with removing connections with only one side of the connection saver soldered down? What about running the positive connection through the PDB hole?
I've gone back and forth on the wire gauge.... I'm bursting to 75Amps total draw when I run Racekraft 5051's so I'm not sure I'd want to go much smaller in terms of wire.
I did have the 14AWG ground wire pull out (break, due to use) the other day, so I replaced it with a 12AWG down to the PDB to hold it in better, and tried to keep my tinning to just the very tip.
No, the positive feeds need to be separated, they can't both run through the PDB hole, one needs to feed the shunt resistor, the other is the return that goes to the PDB, and those do need to be adequately beefy to pass the current.
I am planning on having hte XT60 hard mounted into the PDB, adn running 14awg wire from the bottom of the pdb (where hte pos and neg of hte XT60 go into the holes) to power my FC - will this work? Your last statement above seems to suggest it wont.. but want to confirm.
Not if you want current sensing from the FC as well. You won't get the current draw from the PDB (and ESCs attached) if you just pass those through direct to the FC
How did you accomplish having both current sensing and OSD along with the rubber connector saver?
