Lithium Ion kayak batteries

I saw this pop up on Facepage and thought members here might be interested.

They are not cheap, but being Lithium they are lightweight with the bonus of being waterproof.

I use a Fusion Deep cycle 12V 18Ahr battery ( http://www.batteriesdirect.com.au/shop/ ... 12-15.html) on my kayak to power sounder/GPS, nav lights etc. It's mounted in a Jaycar box with waterproof rocker switches mounted on the box and car type blade fuses. I setup one switch as an overall On/Off and the other 4 Sounder, AnchorLight, Nav Lights, Accessories. The latter supplies power to sealed USB and cigarette type outlets mounted just in fromnt of the seat. The anchor light is a standard removable telescopic LED pole (BCF). The nav lights are LED Green/red mounted in the side of a box which in turn sits on a Railblazer post and plugs into a Railblazer socket with an electrical outlet plug. Easy to put on when needed and sealed up tight when not. (The aluminium structure the battery mounts on is a mount for two outriggers one of which carries a 2.5JHP Suzuki 4 stroke.)

I've recently bought the FPV 17.5 Ah battery.
It's running a Lowrance HDS7 gen3 with Totalscan.
Previously I was using two 9800mAh ebay blue pack lithium ions. I could only squeeze 5 hours runtime keeping the screen brightness to a minimum. The FPV keeps going even with high brightness.
Its pretty compact and light for a powerful battery.

Can vouch for the FPV-Power batteries. I have a little 7 amp hour one and it keeps my Garmin 5CV going strong for 3 to 4 decent sessions before needing a recharge. Weighs next to nothing and charges fast.

Thanks for the suggestion. I now have the 7Ah battery. Now I just have to figure out how to connect up the battery to the finder and add in the fuse and mount the transducer. Not easy when I know absolutely nothing about electronics or soldering. I might go to Jaycar electronics and cry damsel in distress. :lol:

How far is Woody Point from Burrum Heads, Brenda??

DaveC49 might be able to help you set it up!! (Or someone else who may be near Burrum Heads .... if they tell you what you need?)

That little secure waterproof container with switches that Dave put together looks awesome!! :gu:

Jaycar didnt have the right sized grommets to take the plug to the fish finder so I ordered those online. I will be putting the fishfinder in front of me in front of the first hatch and just behind the rod holder (which I seldom use). Its a good raised up surface out of the water in a dragon pro fisher yak. The battery will go up in the front hatch in the round tackle box. I only use the front hatch to retrieve stuff from inside the yak.
