Answer 1

Dog is right but you could add a solar charger to keep it charged about$28 I carry one on my bike only about 4sq inches and 2 wires

Answer 2

afraid youre sol on this one,if it wasnt made to have a battery,there wont be any way of charging it,nor anywhere to mount one

Answer 3

Mark,,You want to add a 2nd battery,in addition to existing one?

Simplest thing to use is a "Battery Isolator".

They're cheap and easy to hook up.

Here's one from JC Whitney..$24 + shipping

You can probably find them on Ebay a little cheaper.

Or,,Locally--most Boating/Marine places  or RV/Camper places have them.

Lots of those things use Multi Batteries.

But those places are usually high priced

.........................................

One thing to keep in mind.

The alternator output on your bike is small.

They have very little excess/reserve charging capacity.

That's typical of many  bikes,nothing unusual there.

On Short Trips,,where run time is short,,,there's not enough Time to charge a battery throroughly.

Ok,,, Dual Batteries connected with an Isolator has  2 "Downsides"/negative effects on Charging.

#1,,the Isolator itself Reduces the Charging output a little bit.

#2,,The Charging output gets SHARED,,,split between the 2 Batteries.

On a Motor Home with a pair of Big Batteries,,Hi-Output Alternator,,,and running down the hiway for several hours at a stretch---NO Problem.

On a bike,,,where all the factors are Marginal---Output,Run-Time,Batt Capacity,,,,,,,,,

That all totals up to being similar to a Very Slow Drain,,,,because of insufficient charging TIME.

NOT an Actual Drain,,,but an Insufficient Recharge

We're talking over the course of several Days at least,,,probably a few Weeks actually.

It's NOT a terrible bleed down,,but a DEFICIT will likely exist.

The Solution is Simple,

Put a small Trickle Charger on the batteries  Frequently.

Maybe 1~2 times a week,,,overnite.

Tuff to guess what ChargingSchedule may be needed,,,it depends on how Ya Use your bike.

Once a Month Charging may be good enough?

It may even Seem to be fine Without Charging the batts at all.

But I gaurantee You,,they'll Last a Lot Longer if you keep them fully charged at least Monthly.

It can be the difference of Batterys lasting 12 months versus 2~3 Years or More.

Just something to be aware of

Good Luck w/ your project
