Best battery jumper?

[onebadgt]

Curious what you guys have on board as a battery jumper? I would like something small but reliable that I could keep on the boat in case of a dead battery.

I do not see many people carrying a booster on board. Not a bad idea with a single battery.

Most setups are a dual-battery setups with stereo systems and amps. My 07 had single setup when I first bought it. I put a relay switch and a second battery.

Then I moved to a bigger stereo and multiple amps and 3 batteries. Same setup with a relay switch.

At the same time I put a smart charger onboard. When I come back from the lake, I plug in, all 3 batteries charge. When they are charged, it goes into 'sleep' mode.

I carry a larger 'Jump -n-Carry' as well, but the new Li-ion power packs will hold a charge for 12 to 18 months. And are much lighter and smaller!

But that doesn't help me weight my boat down for surfing dude...

I have dual battery setup.
But after a 4 wheeler ride where my battery went, buddy had one of these and it got me thru the day.

He told me he has used it to start diesel truck as well.

I have it charged and plan on taking it out with us on every trip.
