Hopefully some of you electric genius dudes can help me out here.
This is in my boat.
Currently I run a dual battery set up in my boat. 1 starts the motor the other runs all my stuff. However the 2nd battery I always either charge it at night. (Pain in the BUTT because of its stowage location) or during the day I run my solar panel on it and it charges it up faster than my fish finder can use it...but the downriggers eat it up...
So I want to put in an isolator unit that charges both Batts when the engine is running and isolates them when the engine is off. So far I have found 2 different types.
One system uses large diodes and heat sinks to perform this task. Seems like it's the simplest way to make it work. However I would have to believe that if it's using a giant heat sink, it's creating heat, which is taking away from my battery charging...not good since I don't use the "big motor" that much in the boat.
The other system I've been looking into uses a relay system which I'm assuming is basically 2 celenoids wrapped into 1 package. With ignition power it flips on and charges both batts. Seems like a good system since less draw on the amps.
Does anybody know which is better?
Here's one I'm thinking about

Here's the other

I'm unsure how the bkue sea system works. I want one that's automatic and I'm not sure if that is or isnt.
Anyone have a recommendation or suggestions?
