Relocate the battery

Thanks very much, Gents.

FYI, the picture looks like mine battery in my 252.

Too bad the EarthX battery is not approved for certified a/c.

Actually, it is approved for certified a/c. Not all, but Mooney with aft battery is included.

Did you have to increase the cable size (AWG)  when relocating battery to  Aft of  baggage compartment location?

How noticeable is it in pitch axis after relocation on a short body C/E model?

 

Thanks,

You see the negative battery lead bolted to the shelf.

I read that you cleaned up the contacting surface of the battery shelf for the ground. Would there be any benefit from running a separate ground to engine compartment (other than more weight)?

I was thinking in terms in corrosion (dissimilar metals ?) and  improving conductivity? 

Could there less noise generated, if a separate ground was ran? I was thinking in terms of  (G5's) magnetometer, autopilot (GFC500 CAN bus ) servo(s) , rotating beacon and com antennas are back there in the tail section.

 

Thanks in advance,

It wouldn’t hurt, but it would be a lot of work and a couple of pounds of cable. I would just clean up the shelf connections and call it a day.

Once you clean the shelf connect point thoroughly to ensure good connection, then you’re using the entire airframe as your negative conductor, so it should be just fine.  Still need to ensure the engine, instruments, etc have their own good connection to this awesome (and big) grounding source!
