I have a topbox, or the panniers.I think the issue is where to put it.
You are joking, right?I have a topbox, or the panniers.
No I am not. As my Stelvio is a 2008 model the wiring is 13 years old. Despite mine and in earlier times, Guzzi dealers, best efforts to clean and lubricate the dozens of electrical connections they will degenerate with moisture, road salt, power washing, etc. As many of them are buried beneath the tank and in the fairing they are neglected. An additional battery will allow sub-standatd connections to pass more current. Simple as.You are joking, right?
Got two different well-known brands, both useless having never worked on any of my 3 bikes and 2 cars tried on. Electrical junk.If you are worried about being stranded and need a way to boost I would look at something like this.
NOCO - 500A Lithium Jump Starter - GB20
The GB20 is a portable lithium-ion battery jump starter booster pack that delivers 500-amps for jump starting a car, boat, motorcycle and more.no.co
But double the current available.You will gain nothing.
Batteries wired in parallel have their capacities added (amp hours) together but the voltage remains the same.
Bike is very well maintained but is now 13 years old, has been kept outside under a cover for some years so has suffered from electrical corrosion. The block connected below the headstock was replaced some years ago as it deteriorated into green dust despite having a full dealer service history at the time and only 20k miles on it.A good battery in good health with clean connections with any Startus Interruptus issues resolved is all I have every needed across three bikes now. In my opinion, that would be a lot of effort for something a bit of attention and maintenance will resolve.
Noted. The alternator should have enough watts to charge both but the effect I am seeking is additional current. Wouldn't a relay negate this?No benefit at all. You are ultimately limited by the output of the alternator. If you take more out of any battery than you are putting in, it will die eventually.
There is also the danger of one cell going down in one battery which will then discharge the other battery.
The only safe way to connect two batteries is through a split charge relay, then have some load on one and some on the other. Thus they are only connected together when charging. When not charging they are seperated, so any problem would not affect both.
You and I have had very different experiences, I have a larger version Noco for my diesel vehicles. The only time it couldn’t jump a vehicle was when the battery was so bad it determined there wasn’t one in the circuit. I had to get one as I had at one point two vehicles with parasitic drains and was tired of being stranded.Got two different well-known brands, both useless having never worked on any of my 3 bikes and 2 cars tried on.

I agree. Rusty's wiring already has 200 connectors, some number of which are visibly and functionally already bad. That's only going to get worse with time, current, and heat, and forcing more current through them to try to overcome the resistance of the corrosion is probably going to heat them up to the point where something will melt (just short of blowing a fuse).My opinion would be to repair the bad wiring. That will resolve your issues. To batteries will give you double the current, but the fusing and corroded wiring will be your limitations. I am certain you could find a used harness and parts online to resolve some of your green dust issues.
But double the current available.
