I'm building a heavy Octo for aerial photo & video based on the APM2 board + Carbon Core Octocopter1000 with 360 Pano Mount and Mega Radius camera mount.
The power is provided by two Turnigy nano-tech 6000Mah 6C batteries connected to 8 Himodel 40Amp ESCs powering 8 Tiger motor MT3515-15 400Kv motors with Master Airscrew 14x7 3-blade propellers fitted.
The theorical maximum amp draw for each motor is 29Amps making a theorical max Amp draw of 232Amps. I want to measure battery Voltage and current draw but the biggest AttoPilot Current & voltage sensor is rated for 180Amps Max.
I know I'ts impossible or near impossible to go to max Amps with all motors at same time doing AP but given that burning the Attopilot sensor will stop the power feed to the multicopter, and this will result in a more than sure crash, I want to be very conservative and not overload it.
Is there an option to connect two 180Amp sensors to the APM2 board (one on each battery) and get readings?
Two sensors should be capable of handling 360Amps and this would solve my problem.
