Post subject:  In Hull Battery Placement
Has anyone with an electric motor on their Hobie mounted the battery in the hull? If so;

1) how have you mounted it so it doesn't move around, particularly in transport or if rolled over
2) how have you brought the power cable and plug to the outside for using/charging it
3) do you have any issues with water getting inside the hull

I'm looking at this for a couple of reasons. First is lowering the centre of gravity when I put a larger battery in, the second is saving space on deck for fishing tackle.

Any suggestions appreciated.

OK, I have seen a few buried posts re battery placement, and a few have said they pack the battery in tight with foam. As I use two 18Ah AGM batteries, I'm thinking of making a mounting tray with a padded, non-slip bottom that can be pushed down from the rear hatch to just behind where the hull dips for the seat. Then I can pack foam at the sides and top to prevent movement. This would work except in the worst of roll-tilt-flip-explode type situations on the yak, I think. It also leaves the rest of the cavity for other storage.

I was intending to get a 35Ah battery, but it is too awkward to handle into the hatch. Easier with the 2x 18Ah smaller ones. From experience, I get about 1.5 hours full power on one small battery with the voltmeter dropping from 13.6 to 12.7V, so three hours is plenty out of two. And they are certainly not drastically discharged.

I have also looked at marine type fittings for the outside of the hull to plug the motor in to. There seems to be a reasonable range of stuff, though expensive. That's something else to research on eBay.
