Any thoughts on using a solar panel battery charger/maintainer such as this one http://www.homedepot.com/buy/electr...-power-sports-charger-50013.html#.USRXxaVJO7x with a TL system to help keep from having to charge their battery ever couple rides. I was thinking if I were to go camping or riding all weekend I could use something like this between rides. Even just throwing it on to and from the lake to keep the battery charged. Think it works or just a waste of time and money?

.067 amps? Might as well use a hand crank generator to charge it.

My antigravity battery has 12 amps. (Battery and solar panel are 12v~) Lets say my battery is half dead. I need to charge it 6 amps. 6/.067 = 89.5 hours to charge. Yay! take a whole month to do that.

Waste of time and money. You'd need something bigger than that. And then you'd still need an actual battery charger to connect it to.
Why not just connect the charger when you get home? It takes less than three minutes and you should be taking the hood off anyways.

In reality, get a high quality charger that can run off 12v. Charge your ski battery off of your car battery. Or buy an extra car battery, good to have an extra anyways. Or buy another ski battery.

I've never had an issue so far with running my battery low with the total loss. I've had all day rides, with constant starts. It's about a year old Odyssey battery too, though I do keep it on a Battery Tender at home.

Just to throw some numbers around, typical solar panels can put out about 10watts/sq ft which is around .8amps @ 12VDC but really you need 13-14VDC to charge so it would be more like .75amps. That would be workable as long as you had good sun, but 1 sq ft of solar cells on a ski would be hard to place IMO.

Why spend thousands on total loss and light weight parts to spend $50 adding weight back to it?

Put a waterproof quick connect charger lead on the battery. Put the same connection on your charger. Plug it in and done.

My dad carries an extra car battery in his truck he runs stuff off of and hooks up one of the panels up to it that you linked. He seems to be happy.

put 1 or 2 car battery's in your ski box on the trailer hooked up to chargers and leave the trailer plugged in. Switch to an enclosed trailer and mount one of the bigger 3x4 solar panels like the one harbor freight sells for $150.

Put a second battery in your truck (my silverado come stock with a place for it) and charge off the battery.

Just buy the little charger and plug it into your battery and let it sit there if it makes you happy. Probably wont do much. If your camping on a long weekend and they don't have power and they don't have tree cover, find a new place to stay.

But don't mount it on your ski. Might as well put a hood ordiment on it and claim it gives you better pop by preload.

You know your be laughing at the guy who bought a lightweight battery then mounted twice the weight savings in a solar charging system.

That's a good idea actually. Just tell everyone it's a solar hybrid, we've gone green. Maybe the EPA will let Yamaha gt back to producing some motors with balls.

The voltage controller only weighs three ounces with a one square foot solar panel weighs around eight ounces and with the wiring install would still be under one pound.

The only weight saving with a total loss set up is from the 1.78-lbs flywheel because the control unit and coil packs are about a pound more than the stock e-box assembly.

Also keep in mind that expensive lightweight lithium battery will be useless when it drained below 10.5-volts.

Indiscriminate, willy-nilly charging of the same spendy LiFePO battery by some DC output controller attached to a PV string is not going to be exactly great for the battery. That controller only ensures a steady 12V output. You need an actual battery charger to handle the charging. Many of them can operate directly with a 12V input.

I made a portable charger using a ballistic as my 12v source, since that's the only good use for it. ImageUploadedByTapatalk1361485596.467833.jpg
My antigravity will likely go 2-3 days with a Dasa 1100/220 psi TL. Ive run over 12 gallons in a day and never had an issue. The portable deal is sweet for laying in the tray and charging if needed. I can get 2-3 charges before needing to recharge the source battery.

As I quoted in the 'total loss battery' thread, get the turnigy charger from hobbyking. I simply pull my trailer up next to the car half way thru the day and whack it on charge for 10 mins. If I cbf doing that, I've got a backup drycell battery in the car- throw that on the ski tray as well as the charger to top it up on the beach
