Battery Back Up Solution

I know most of us have been frustrated at one time or another with the lack of battery juice if the bike doesn't catch almost right away.

Here's what I did and it works unbelievably well:
Get one of the mini jump starters, I bought a Bestek around $40 its the size of a typical cell phone. I wired it directly to the battery posts through a on-off toggle switch which I located on the frame just to the rear and below the seat. The module I Velcroed to the rear fender under the seat.

If you go to crank the bike and it sounds like its struggling, flip the switch and I guarantee that little jumper module will fire it up instantly.

I have never seen a more useful product than one of these units. I tested it on my Hemi and it started it 6 times before even needing a charge! Well worth the money for peace of mind.

Great idea. Those little jumpers are very good. I keep one in my wife's car and used it on my Yukon once, worked so well I shut the truck off and did it again just to make sure it wasn't a fluke. Did you run a fuse just in case? Not sure if that would help with Kevin's concerns but couldn't hurt.

Im not sure what electrical issues are being created, even if the switch is left on it doesn't add any current to the bikes existing electrical system. Its virtually no different than the regular battery hookup. A fuse is not necessary as the additional current is only supplementing the existing battery and not adding any voltage.

yeah, yeah, me gots one too!! The battery in mt truck was getting flaky because my GPS and DashCam had
never ran the battery down. Used the little thing and BANG up and runnin in seconds. Now the new battery
has no issues with the electrical draw. I DO keep the little jewel in my tool box just in case I need it for someone
besides ME. You can buy one that you replace your bike battery with BUT they are costly. BEST $29.00 ever spent.

I carry around an XP-3 like shown above. It easily fits in jacket pocket with cables in another pocket. Since my Braille is 4 to 5 years old, I don't leave home without it. Also, my Daytona 675 is another bike I don't leave home without XP-3. It's battery is very small to save weight.

First thing to come to my mind is charging of the external battery. If you leave it connected and VR starts pushing 14+ volts to that lithium battery it may well explode right under your nuts. That is why they tell you to disconnect it within 30 secs of starting...

I think the antigravity ones have a protection in them to keep it from backcharging.
