UNILUG
One thing I hope to do is upgrade the battery terminals on the auxiliary battery using the Unilug. Full technical specifications for the Unilug here. The product guide will answer most of your questions aiout the Unilug.
Warning: the clearance on two seater models is less, so greater care maybe be required before installing the Unilug. I will use it on the positive and negative terminals. The Australian designed Unilug looks like this (my Blog has more detail here):
BLUE SEA SYSTEMS TERMINAL MOUNT BUSBAR
That way I can configure the batter terminal I way I need. One terminal post will be a bolt rather than standard battery terminal post. On the positive bolt terminal which I will install a fused Blue Sea Systems ST Blade ATO/ATC Fuse Block, letting me fuse small amp accessories at the battery (like my dashcam, etc). (There will still be room to add other cables on the bolt terminal.) The Blue Seas terminal looks like this:
Specifications of the Blue Sea Systems ST Blade ATO/ATC Fuse Blocks are:
I will use an unfused Blue Sea Systems Terminal Mount BusBar on the negative side, if needed.
Specifications of the Blue Sea Systems unfused busbar are:
The Blue Seas Systems busbars, both fused and unfused, are tin plated copper.
My Blog post has more information on all three products here. Since writing, the Australian price of the Unilug (twin set) has gone up from AUD49 to AUD69.
For Australian owners, I noticed HSAUTOPARTS is offering the a positive Unilug and the BlueS eas Fused Busbar in combination for AUD79.95. Look here (image from their website). Warning: positive side only not positive and negative for the Unilug or Busbar.
RAZED PRODUCTS BUSBAR
Razed Products has just announced another option, instead of the traditional busbar, called the Unifuse, using MIDI fuses. It comes in single, double, triple or four fuse version. It is nice to have choices.
BUSBAR ANOTHER OPTION
You could also run a wire from the second battery to a new busbar, like the Littelfuse FHZ busbar, and wire the accessories off that busbar. The Littelfuse FHZ busbar is better suited to the accessories drawing higher amps, a smaller busbar may be suitable for smaller drain accessories like those from Blue Seas Systems.
Then find a a vehicle earth for the negative side of the circuit, or use an unfused Blue Sea Systems Terminal Mount BusBar.
Choose the system best suited to your needs.
CONCLUSION
I do like how the Unilug and the busbars have covers limiting accidental shorts.
Since writing that blog post, I can see a few more options are now available on eBay.
Post what you are using or intend to use.
