"jbabio, I  have a heavy Y6 built a few years ago and still in the air.  In my case I have three parallel 5s, 5000mah batteries.  It works for me and my Y6, but I would not recommend three parallel batteries as this creates battery…"

"What is the correct way to connect the AttoPilot 180A ground wire without causing a ground loop when using two separately fed 6Ss into a PDB while only sensing one of the packs (I only want to monitor 1 pack)? Pixhawk is powered via the top power…"

"In my case with parallel batterys, I used the Attopilot on only one battery feed.  The voltage is correct, and I adjust the pixhawk parameter to adjust "amps per volt," to compensate for the additional current.  With a little…"

"Warning, using attopilot with draw more than 180 can be dangerous because the power consumation grow wtih square of current : P = I² * R actual attopilot for 180A : 180*180*0.00025 = 8.1 watts if you draw 272A 272*272*0.00025 = 18.4 watts"

"In the end I've bypassed the attopilot completely and have the current /voltage sensing done via the frsky. Less to worry about and I never liked the way the atto looks so easy to short!"

"Same problem for me guys.. I need to use 12S battery connection and 220A current draw at max. Is there no simple alternative to AttoPilot180A ?"

David replied to jbabio's discussion Current sensing (safely) for Heavy Octo?
"I know this thread is a bit old but is there any further info on this? I am also looking for a sensor that will work beyond 180A. Ecalc tells me my max current will be 217 so not too far over and I probably wont go that high but I don't want…"
