    Default Battery Choice for EX-2

    Is there a recommended main Battery model, I measured the underseat box at 217mm x185mm x 100mm ?
    The usual LSA choices locally don't fit in the battery box.

    Being an EX-2, battery choises are pretty much left to the builder.

    Not sure if there is a 'recommended' battery. There is a battery listed on the CC Store web that can be used for your plane. It specically does not list the EX2, but does list the FX2, which, if I'm not mistaked is the factory assist version of the EX2.

    CC Store only list the height, but Aircraft Spruce has the full dimensions.

    Where is NZAR?

    I chose to use an Odyssey SBS J16. Hot or cold, engine or temperature it spins the engine over to a start in 2-3 seconds.
    There are lighter options.

    Follow-up
    Battery began showing starting stress at approx 150 hours now at 170 will be replaced. Disappointed!
    I'm not yet a fan of Lithium based batteries in the plane so searching AGM, any current thoughts?
