Second Battery

[Simon Spitale]

Hi all, I have a MK5 Zenith with a single 105Ah lipo battery. The wiring is there to add a second. Is there anything else is need to do or simply hook the new battery up?
Any suggestions or recommendations on second battery size or brand? Cheers

Hi Simon,
  The standard track design is to directly wire both batteries in parallel, so both batteries should be the same.

My preference is to also add protection and isolation between the batteries.
While there are several ways that this can be accomplished, one of the easiest ways is with a standard marine style 'Manual Battery Switch'.

Yep - I've installed one of these marine switches too.
