    AGM for Fast strike

    My Battery for starting/electronics is going dead during the day. Fishing mostly small bodies of water, there is not a lot of running.
    I was looking at an AGM, but have read that they are not good for stator motors.

    Is this true?

    Just looking at the options, an know I should off load my electronics to a sparate battery.

    AGM Batteries are just fine for the engine. These are used every day for many many years for your type of engine. AGM are still a “wet” battery.

    don’t confuse with lithium ion batteries - which are ok when properly installed.

    Properly installed is intended to mean installation to ensure proper charging per LIon battery specs as EVJO outboard charging systems are designed for lead acid batteries - not LIon.

    My understanding is the lithium batteries should have what's called bms, battery management system, which is an added part, or charger, to keep voltages between the stator and battery's in the proper range.

    ++ to Bassmeister. The need depends on the LIon battery manufacturer.
