I have an argofet box connecting the outboard alternator to 3 lead acid batteries, one start, one windlass/thruster, one house.
I would like to replace the house battery with a LiFePO 4 battery. For ease of install simplicity, can I connect one output of the argofet to the input of the Orion DC-DC?
I have the same question.
Below image is screenshot of catamaran electrical system. You can see the blue line to engine battery ad the green lines from alternator and to batteries.
I am replacing the batteries with lithium.
I would also like to be able to report engine battery voltage in Egrano/Cerbo GX
Any tips appreciated.
Thanks
Nobody has yet given more information, so I will just write my own reasoning.
A MOSFET is/acts just like a one-way electronic switch. Any MOSFET device will split the input voltage between the outputs while electrically isolating them from each other.
In my case, I want a LifePo house bank along with an lead acid bow thruster and a lead acid starter battery, all fed from the alternator.
Electrically, we do need the Orion at all for the LifePo bank as there will always be another battery connected to the alternator. But I am introducing the Orion to control the charging profile.
My boat is stored for the winter, so I am waiting until the spring to do the install.
Sorry for late reply. Now I’ve seen the topic.
Yes, you can.
More of that, if the Orion is an isolated type DC-DC converter / charger, you can even connect the Orion input before the Argofet, not on one of its outputs. Meaning connect the Orion input directly on the alternator.
Thanks for the insight. The Orion XS is not isolated so I suppose I cant do that. In the scenario with the Orion XS after the argofet will it have any voltage when engine is not running? I guess not, and therefore the Orion XS will be turned off, correct?
Thanks again.
You are correct, no voltage when the engine is not running.
