    Being in a yak you would want a small size and light......I've just been looking into Lithium Ion batties to run a fridge in my car.......Li batteries seem to be getting much cheaper and more available with better run down rates and shorter charge rates.........Pretty much a 40ah Li will do what a 80ah AGM will do at 1/4 the weight......Still not cheap but definatly better technology.........40ah LI can be bought for around the $350 mark if you shop around on the net and would weigh about 6kg compared to a 80ah agm that will weigh 25kg and the Li will have a much longer service the thousands for re-charging.

    Google LiFePo4.......check it out.

    Confidence.......the feeling you get before you fully understand the situation.

    I have been researching a 34lb.

    I read on web somewhere that, for a Hobie Outback,
    a very rough formula is 1 mile per 5 amp hour,
    so 40 amp/hr = 12 kms.

    Get a battery with bolt/screw posts.

    check everybattery website,
    free postage if under 15kg, so could get a
    40amp 13kg fullriver for $162.

    Thanks Dan, I didn't realise there was that much difference in weight/performance.

    Mate an AGM by Fullriver is a good choice. Mount it upside down, sideways etc. I got one that suited my rideon mower so i didnt have to buy 2 different ones. My little 12 pounder runs for several hours on this size with my Garmin 128c also which is pretty power hungry.. □DC35-12A. 35amp hour and you can run them down lower than a lead acid.
