Hello
For context I am working on a ASV catamaran with 2 pontoons as a school project, the plan is to have 2 Lipo batteries in each side with a decoupler after each battery in case a battery shortcut.
My Flight controller is the “The Cube black.”
My question is now, how can I monitor the batteries? For each of the power input on the flight controller there is a volage and current sensing but only for 2 batteries.
While looking for an answer I stumbled upon this forum post from 3 years ago.
https://discuss.ardupilot.org/t/rover-docs-why-so-many-battery-monitor-settings/40030
Is this feature implemented yet?
in the parameter list it is listed that you can monitor up to 10 batteries at the same time. How can I config the aux ports to become volage sensing ports.
If that feature is not implemented yet I was wondering if anyone had experienced hooking up battery monitoring like the sketches below below or if that is a stupid idea.
The Green boxes are the pontoons,
PS. The Batt_mon is just to monitor the voltage from the batteries. There are voltage regulators and fuses before the flight controller receives power.
Feel free to question if I missed something or something does not make sense 
Thank you
**Best Regards **
