Over the last wee while I have been planning and amassing the required bits to fit a dual battery system to my Isuzu DMAX 4x4, it is an auto and with a dead battery, it is dead in the water.
So, while a mate was fitting the system to my truck, I wondered out loud if a similar set up could be fitted to my Rocket 111??

The second battery in my truck is portable and as most of my touring on the R111 includes a small trailer we setup the battery in the trailer.

The battery case is fitted with Anderson connectors from the isolator/Charger, solar input, 2x 50amp outlets for appliances etc, 2x cigarette outlets, 2x USB outlets and a voltmeter for the battery, all fitted into a plastic box with a lid.

Long story short, Yes!! A basic electronic Isolator at $60 AUD into the space where the air filter used to be, $50 roll of appropriate 100amp cable, a 60amp fuse and a couple of extra Anderson plugs.
A flat battery whilst traveling is now, hopefully, a thing of the past!!

Thanks for reading about my little project,

Mal the Kiwi.

Well done. It's great to watch creative minds at work.

That is a cool project and a great idea! My diesel pickup has a factory installed dual battery system; but I had never thought of dual batteries for a bike. For a bike towing a trailer, it is a great idea. TUP

I don't know the output of the Alternator , but generally, its wise not to have big thick cable and big fuses permanently connected to a system.
I would want something about 15 Amp fused , doing the normal charging of the Paralleled up battery. The 100 Amp Anderson Plugs , I generally would leave disconnected , until the died circumstance, that you need it. There are also some pretty Dandy Coupling Devices out there , for alternative supplies , and with a Trailer , a small Solar Panel is Pretty Light. For when your stopped for a few days.
I think the idea is not to use the Bike Battery at all for Trailer Auxiliaries.
Just giving you something to think about.
It takes a lot of time to do what you have done.
