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 !
All I can say is my 2000 model 200 2 stroke Yamaha seems to be getting along fine with an Impulse lithium 120 ah.
Probably close to a year now and no issues.
