Dual Battery Setup???

[Rescue Wagon]

You could and that would provide you more amps. The reason for the setup I'm trying to put together is to protect the battery responsible for starting the bike, so I won't get stranded by running it down which can happen if you just connect them in parallel.

Thanks for the response. I was thinking it would be easy and quick to rig up and I would take it off the bike if I were running anything off it at night. That way I get what's in the battery and that's it.

I was thinking of 2 x Lion batteries due to the weight savings. Is this technology a good reliable replacement to use. I will be adv touring and am currently in Colombia.

cheers dave

Am quite interested in the theme of this thread and would like a lighter, more powerful, efficient, and dual set of batteries...these similar style batteries are causing Boeing's 787 Dreamliner issues are they not? You're riding somewhere perhaps a very remote area and you catch on fire....freaky sh*tters...seems like we're looking for our own electrical Holy Grail

Are you referring to Lithium Ion Batteries?

The technology has been around a long time. The military uses them for portable radios and chemical warfare agent detectors. The main issue is they don't like water.

...am I missing something here...DaveBurton is asking of something different with Lion batteries than my query?
and if these batteries do not like water (moisture) is a dual sport bike not going to splash some water or ride in rain..?....I'm in the Pacific North Wet....getting (myself) more questions than answers....

[daveburton]

I think Lion is the same but as I said I don't know much about this stuff.

[Rescue Wagon]

They are sealed, so the water only becomes an issue if the battery is damaged and water can get in.

[daveburton]

Rescue Wagon, you seem to be technically competent in the field, do you believe that using Lithium Ion batteries is a logical and reliable improvement.

Based on what I have read it looks great on paper, light and holds charge for long periods which helps for long trips when the bike gets stored for months.

Are the batteries called Lithium Ion, LION or what. Is there an official acronym.

Just want to make sure there are not 2 separate technologies that are getting confused.

thanks dave

12 volt and 24 volt Smart Battery Isolators with 80+ amps pass through and solid-state control		Battery isolator (or split charge relay) allows an auxiliary battery to be charged by the vehicle's system, yet prevents the starting battery from being run down by your equipment when the engine is off.
I carry a C-pap machine with me when out traveling & camping. I use this to charge my PC925 battery after each use. It is always charging & connected to the main battery but when the main battery voltage goes down to 12.6V it disconnects the auxiliary battery. The aux battery is parasitic only until the main battery drops to 12.6V then the two are disconnected. Have been working for me since 2009. Cheers.

LION = Lithium Ion

My experience with them is that they are lighter and smaller for the same amount of output as other battery types which is why you find them in iPods and Smartphones. They won't develop a memory like some batteries can and they are capable of being charged and discharged numerous times with little issues.

The downside is they typical only good for two to three years and that time starts from when the battery is manufactured, so it seems like a very expensive investment when you look at the price of the LION motorcycle batteries.

My setup is two traditional batteries, battery isolator, and battery tender to be able to camp at night and insure in the morning my bike will start and all my accessories will be connected to the second battery as well, so once the bike is turned off if I leave my Ham Radio on it will only be able to drain the second battery and not the starting battery.

Hi Dave...I don't think it needs to be mounted in a case. Mine is mounted on an (aftermarket) air cleaner unit on my Ural. Won't hurt to put silicone sealer where you might think water could get in. Just mount it under the seat or some place where it is shielded from direct water exposure. I've had mine through some rainstorms & seem not to be bothered by it. There's a small green LED light that is lit up when the two batteries are connected. It goes off when the main battery voltage goes below 12.6V. I kept my installation simple, there are other features though. Neat little unit...it has survived since '09.
