Posted this on the multi rotor forum, but this may be where is should have gone.
I really like knowing the voltage and current used when flying, but the Attopilot 180a is like the size of a postage stamp! Is that completely reliable? I put one is a Tarot 960 with 5010 motors, 18" props and a pixhawk with a single 6s22ah pack. That setup has proven excellent. But now I’m building a Foxtech D130 (1300mm X8) with U8pro motors, 28" props and two 6s22ah packs. Things are getting a little more serious. Especially considering it’s also carrying a $170,000 lidar. The lidar only weight 2.5kg, so I won’t be driving a lot of current through the Atto but it could be a fail point. Would it be a better idea to run one pack through the Attopilot and the other direct to the distribution board? I’d only be monitoring one 22ah pack, but I could live with that. I’m sure there’s some internal resistance through the Attopilot as well, so the packs may not discharge equally but again it may not be a big deal. Or should I just run both packs through the Attopilot? Could just be overthinking all this lol. One last thought, what is this power module so small? Anyone using 180 amps isn’t flying a micro quad lol! If you look at the picture, 12g wire is a challenge soldering, let alone 10.
