    Default What Battery Do You Use?

    I'm in the process of selecting a battery (likely an AGM). In reviewing the batteries mentioned in this forum, I'm am surprised at no mention of using a Yuasa as these seem to be almost the default battery on motorcycles.
    Is anyone using Yuasa or have rationale for not using one?

    I use a Deka ETX-14 AGM battery. It was the original one offered with my kit by Kitfox. For me it doesn’t make much sense to use a light Lithium battery. I could buy 4 of the Deka batteries for the cost of the Earth-X. I have a relatively low total electrical load, and my airplane is already fairly light. A little extra weight firewall forward is actually desirable for my CG. That’s just my airplane. I built my own battery box.

    I see from the Kitfox parts catalog, the earthx is going for $379. I would think Kitfox owners would get a discount. .. no ?
    So, $379 + $60 for the bracket = $439 total... What justifies this kind of price ? compared to the other lithium aircraft battery available ?

    Odyssey PC 680 AGM over here. Even with the poundage of the old odyssey, we load the plane with myself, my wife, full fuel and 140# of camping gear/baggage within W/B. The AGM batteries aren't fancy or hi-tech or anything, but seem to be long lived, quite durable and get along with little attention and survive period of disuse with little/no loss of charge. Don't know anything about other AGM brands. Also, others experience and mileage may vary.

    On the cheaper side, I run a 300 CCA lawn tractor battery. It spins the 912 over in my Kitfox 4 just fine. Same one in the Avid Flyer and Jabiru engine. Cost is about $30. JImChuk

    Cranks incredibly fast on my 582. The 582 needs pretty good cranking speed to start in cold weather. This beat an AGM by a long shot. No problems.

    Does noco have any customer service if any issues arise ? amazon shows $161.96.. wow, that's cheap ! 7Ah capacity is all thats needed apparently. 600A starting current, wow again..
    I wonder how much starting current is actually needed to start my 912 ? I dont read anything about any balancing capabilities in the BMS. For something so fantastic, and so cheap, why are there ANY bad reviews? , I tend to believe them more so...

    Don't know about service because I haven't had a problem.

    I use EarthX for these reasons in spite of its high cost:
    • Fully built-in, proven cell balancing and safety circuitry.
    • Now certified for use in certified aircraft.
    • Lithium-Iron technology-safer than Lithium-Poly.
    • 10# weight savings compared to AGM.
    • Great cranking power.
    • No need for trickle charger.
    • Panel mounted fault light.

    I don't think you can get all these features in the cheaper RV/motorcycle batteries.
