Dual power supply - Interbus wiring?

Hello guys

I am helping a friend with a 100cc Extra 300.
It will have 1x VPlane and 1x VBasic.

He wants 2x 2s Lipo batteries to power it.

In the VStabi Macrocell write up there is 1 line of text that confuses me. Highlighted in Attachment v1.

Would it be OK to wire 2x 2s lipo batteries in parallel like in attachment v2.

or

Is the text (attachment v1) saying they can be split, like in attachment v3?

If both are OK, which would be better?

Thanks.

Regards
Paul

Hi Paul,

I would go for the parallel wiring, if one battery fails, the other one will still power both NEOs.
In v3, in case the power supply to the master NEO fails, the Extender still has power but no control any more.

It always depends where the NEOs are located and what they are good for, though. If far apart (big plane, one in the fuselage, two in the wings, or one extender in the tail fin, just for receiver redundancy), the interconnection would only need to be two thin wires if each had it's separate power supply.

Kind regards

Hi Eddi

Thanks.

It will have both Neo's in the central part of the plane, so simple wiring.
Thanks for the quick reply.
