Has anyone added a second battery yet for the accessories
what did you use for an isolater and battery tray
the yamaha kit is somewhat pricey at $580 but the convinience of having everything made to fit is somewhat appealing

That Yamaha kit is a ripoff. Just get this instead .

High Capacity Battery by Full Throttle Battery - Yamaha Wolv

You can make your own with a $20 Ford stater solenoid from an 80s model pickup. Its not smart and just acts like a large relay that shuts one of the batteries off while not running. The other problem is if you have a battery going bad, it may drain the other battery while running.

It's better to have an upgraded charging system along with dual batteries. Unless you can keep them charging, dual batteries are kind of a waste of money and space.

You don't need a special batter but if you want the same physical size its a U1 battery (U1R is reversed terminals).

Then just figure out the wiring. Isolator, relay/contactor (depends on how much current you want to allow to flow). But a mount with its location is the biggest part of the job. Note, the battery will still run down in time if you're drawing so much current and not able to charge it while drive or beyond the capacity of the charging system. There is a limit on how much current and time it will work for.

Where does the second battery mount? Doesn’t look like much extra space under the hood.

Under the drivers seat.

Ok Thanks I was wondering where it would go.

 

[Mike_123]

According to the yamaha site the kit mounts the battery under the hood
im thinking it must go on top of the existing battery

I disagree
with dual batteries and a smart isolater your charging one or the other but never both
its worked quite well on my past machines without upgrading the charging system

its nice to shut the machine down leave the lights on and the tunes playing for hours without worry of starting up and getting home

Wolverine X2/X4 2nd Battery Kit

The last thing you need is to be stranded with a discharged battery. This 2nd Battery Kit enables the use of two batteries, saving the main battery for essential functions like starting. If both batteries need charging, the main battery is charged first. Kit mounts underneath the driver seat...

If you're using an audio Power Amp and or High power Auto deck you could run the battery too low to start. Especially if the music put you to sleep and left on.

There are solutions yes, don't know if I can type that much. Simply put connect the system to the Aux battery. Have the batteries in parallel and an an assessory 40A relay (easy to find) engaging with the engine running. It will be charging while running and relay goes off leaving the primary battery as it was when the engine is off. You can also add an in series switch to overide it latch even if the engine is on if desired. Brain is smarter than some circuits. There is always a way. You just need the understand how its all functioning along with the pitfalls of situations. Voltmeter connected to the primary should be a must to be sure do don't get screwed.

Nothing worse than turning the key and hearing only a click. SOL is not a good feeling and anything you can do to prevent that day from coming is worth it to do. Many options and ways to go about it.

Lots of battery isolator made or you can make your own.

Lithium batteries with built in jump start are a option.

That's funny...but we all know here in America. Canada has never been very good at stuff. LOL.

 

[danielplace1962]

Yes sir it surely does.

Says it is the RMAX2 kit. I believe the US description is correct for either countries kit. Same SKU number so it must be same.

Second Battery Kit - Yamaha Motor Canada (yamaha-motor.ca)

 

[Maggot]

From Yamaha Canada... "No loss of cargo space as it mounts underneath the hood".

If there's room under the hood, no question, that's where I'd put it. Less wires, it's all in front for easy access.

Leaves more room under the seat for storage, a heater, and a sub.

They put the wrong description for the SKU. Same SKU as Canadian version so my guess is it goes under the seat.
Doubt the same part is going to bolt in two different places.
