    Technically, they don’t advise against it. They do have caveats though.

    I saw that thread I think. It was referring to the G2 but I assume there really isn't a big difference in the way the battery would affect either of those. I also assume that since ranger is putting them standard on their new boats that it shouldn't be a big deal? Just wondering if there was a big contraindication for using them or if someone has had an issue

    This is a bulletin that Evinrude sent out to their dealers.


    No. 2017-02(D) Models: All Evinrude® Outboards

    SUBJECT: Revised Battery Recommendations

    This bulletin is to inform Evinrude dealers of a revision to the battery recommendations for all Evinrude outboards.

    The battery charging system of Evinrude outboards is designed for use with lead acid type batteries ONLY, including “AGM” and “Gel” type batteries.

    If other battery types, such as lithium ion batteries are used with an Evinrude outboard, installation of additional equipment may be required as defined by the battery manufacturer.

    American Boat and Yacht Council (ABYC) specifications state:
    “Lithium Ion Battery systems pose different risks from those encountered with lead acid batteries and should only be installed and maintained in accordance with manufacturer's recommendations." Failure to follow the battery manufacturer recommendations may cause the battery to fail, resulting in a fire or explosion, property damage, and serious injury or death.

    I doubt that the statement came from Evinrude.

    From what I have read I thought that the
    battery wouldn’t hurt the motor. The charging
    system would hurt the battery?

    It's all about the Evinrude charging system and how it is not designed for lithium batteries which require special voltages and procedures to work properly.

    Of course the choice is yours. If you are under warranty, then there could be problems with electrical coverage as the battery would be counter to factory recommendations.

    Just asking. 12v coming from a battery is 12v no matter what kind of battery? Not arguing just want to learn and understand.

    I agree with your thinking however I feel like his quote and current thought is that the ranger charging system may cause the problems and need to be upgraded to work properly. Not an issue with the battery powering stuff on the boat.

    My understanding is the battery HAS to have a BMS built into it. ( battery management system) Some are running lithiums with BMS but I follow Seahorses recommendation as he is the premier BRP guru in my opinion.....especially if the engine is still under warranty....

    Some lithium batteries are not tolerant to being overcharged. The alternator may put out 14.2 volts, not just 12. Some batteries may have issues if charged to that level. Another thing is the current. Some lithium batteries can only accept up to 50 or maybe 100 amps of charging current. Any higher voltage or higher current can be dangerous. That being said, high quality modern versions, like the Relion 100HP can handle 100 amps continuous charge, which is more than the alternator will ever output to the battery and if the amps or voltage input exceeds the batteries limits, the batteries built in BMS will protect the battery. Again, some smaller or cheaper batteries or batteries with different chemistries may not handle those inputs or have a proper built in BMS. As indicated in the press release, it depends on the battery. The battery or additional equipment is going to have to be responsible for charging properly and protecting the battery because the charging system itself is not made for lithium’s.
