Default Dumb question regarding yamaha 150 2 stroke and charging.

I have a 2001 150 carbed 2 stroke. I keep reading about all these great acr/vsr relays.

I understand how they work, my question is are they really ideal on an engine like mine that does not put out a lot of juice? Not sure on my exact charging specs, but it seems likely that an efi,dfi, or 4 stroke would have a better charging system.

Am I correct or way off base here?

Thanks in advance!

What are you trying to charge with a potential ACR/VSR?

Just 2 batteries. Not sure on exact size yet, but a cranking and deep cycle.

Assuming that you start the day with a well charged set of batteries, your engine has enough charging power to allow the dual battery VSR setup to maintain both batteries at a good level, completely automatically and worry free. The other assumption is that you are running a decent distance - say at least 15-20 minutes each way where you will be at cruise revs.

At least part of the benefit is the worry free element, you dont even need to think about switching batteries on and off. And, if you arrange the batteries so that one is a dedicated start battery and the other is house, it helps protect electronic devices against spikes when the engine is started.

I use the BEP dual battery cluster that has separate on/off switches for both batteries, plus an emergency parralel switch to join them if the start battery fails. Been perfect for nearly 5 years.

Your rectifier/regulator has an output of 25 amps. Not a lot but enough to recharge two batteries. Over time anyway. But not a lot of time if you start with fully charged batteries and you don't go hog wild with your electrical requirements.

If this is a saltwater boat where the need to start the motor can be critical, then a combiner/ACR/VSR can be very useful. However, in the case of your motor it can be started manually so having one or two charged batteries is not as important as it might be to others with motors that cannot be started manually.

Having said that, for convenience if nothing else, I recommend the Yandina combiner. Most bang for the buck and a whole lot simpler to install. Connect three wires to your existing two batteries and you are done. Remove the nuts from two positive terminal posts and one nut from your negative terminal post. Put the Yandina ring terminals on the battery posts. Reattach the nuts and that's it.
