Been wanting to replace led battery with lighter lithium but love been seeing lots of things that say yamaha dont work with lithium . I have a 2006 yamaha 40 hp. And want to know if this is true some say if battery has BMS it will work.
Can someone set me straight. Thanks !
Call or email Yamaha with your questions.
Very good customer service.
Can't think of anyone who would know their product better than than the actual manufacturer.
Good Luck

I’m running Impulse’s All Purpose with my 02 90hp Yamaha with no issues. This battery has a BMS on it.

Run 2 Impulse 60A/H on one boat and 3 LiTime 100A/H on the other for the T motors.
Run AGM on the crank batteries since one motor is under warranty and the other motor (Yamaha) says not to.
I don't know the type of charging system the OP has in the Yam 40, so I recommended contacting Yamaha directy to be safe.

Best is call the battery manufacturer all Lithium's have a BMS.
All I can say is my 2000 model 200 2 stroke Yamaha seems to be getting along fine with an Impulse lithium 120 ah.Quote:

Good to know Jeff!
I've read a lot on this and stayed with an AGM starting battery on my set up. What I read from multiple sources said a lithium STARTING battery will do a great job for most folks under most conditions. The issue with them is if something occurs that causes the BMS to shut down, there's no where for the voltage being produced by the alternator to go and that brief but immediate surge can destroy the alternator and or accessories operating at that time.
Just what I've read, so take it for what it's worth.

As I understand it, my main battery disconnect switch says stop engine before switching off. I imagine a single lithium starting battery, if the bms kicked off, it would be like switching that disconnect off while running.
