One for Elgin
I was wondering whether you have any thoughts on the suitability or otherwise using a lithium starting battery with a G2.
I was thinking that through your previous line of work you may have seen them due to weight advantages and seen what types of issues that may arise.
If they are no good for use in G2’s that fine – better than an expensive misinformed mistake – or if property set up with a MBS and an A-B charger - no issues – then will look at loosing 45kg - 100lb of lead from the back of the boat.
In a previous thread Seahorse posted the following from advice from Evinrude

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.

I have been using a Relion for a year now. No issues. If you carefully read what the Evinrude statement says, it’s not that the battery will cause problems with the engine, the concern is the charging system may cause problems with the battery. Charging with too high amperage or to too high a voltage can cause damage or even cause a fire with a lithium battery. That’s why Evinrude releases their statement. Buy a quality drop in type lithium with a good built in BMS and the BMS will handle it all. It will work just fine with no issues.
Recommended charge voltage for the Relion RB100-HP is 14.2-14.6 volts. The charge voltage of the Evinrude G2 is 14.4. There is absolutely no issue with reduced capacity due to charging limitations.
