Battery Location ?

[K-mac]

Battery Location ? I see a lot of air boats with the battery
a foot or two above the deck. Is there any reason for this
seems this would be an easy way to help lower your center
of gravity a bit, and that would be better don't ya think ?

I try to put mine where it is easy to get to. I used to have it bolted to the T bars at the bottom inside the cage and it was a real b&*ch to get at. I now have it under the rear seat basket with enough room to lift it out of the tray/plastic container and room to connect jumper cables without creating spark.

We always put ours about a foot or so above the deck depending on the boat. A lot of the location has to do with just where it fits best. Is there enough clearance to lift it out of a box. Does the throttle cable interfere with it. On our boats we always had to offset the battery a little to the left side so the stainless throttle cable could run a straight line to the carb. Another thing to keep in mind is the spacing between all the other bars on the back half of the cage where the screen wraps around. Where the straight pipes are welded from rear hoop to the seat back, we would match the pipes for the battery frame at the same point that way all your pipes meet at the the same point for a cleaner look. Do not put the battery below the deck. Because it will spark and that hull can be full of fuel fumes. I have seen boats blow up because of it.

I have heard it said the higher up it is the shorter cables ya run. I mount mine off the base of the motor stand just over the runners and on the opposite of the torque side.

If ya have a cable length problem you need to work on other problems first before ya decide battery location. There should be no battery cable length issue in these boats.

Some like to keep them high so they dont flood in case they get swamped. Some say swamping doesnt kill their battery.

I still vote for low in the boat..

I mounted mine about a foot off the deck. As far as cables go, just stop at any welding store and buy 10' of #4 gauge cable. Make sure you buy copper lugs for the cable also. I solder my lugs on the cable because crimped lugs will always fail it is just a matter of time. I also have #4 cable from one head to the other, and from the front of the head to the battery. The motors most of us run are not stock and they need to have good grounds and good power feed.

My opinion is any thing you can put low in the hull in order to lower your CG is the way to go. I know many boat builders who mount the fuel tank and battery in the same compartment with no problems . I personal think airboat battery's are mounted high because it is easier and cheaper , by cheaper I mean is with the engine mounted high and the battery low you will need a heavy gage wire so as not to lose amps form battery , heavy wire is more expensive and sold by the foot thus the reason (or my mounted ) why most battery's are mounted high. I personal like the welding cable and use 00 in many projects form dune buggy's to boats and heavy equipment
