Yamaha n lithium

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.

I agree 100%

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.

I run a 100ah impulse lithium starting battery in my 60hp Yamaha. No issues whatsoever in the past 3 years.

Best is call the battery manufacturer all Lithium's have a BMS.
