National Luna Intelligent Solenoid & Dual Battery Controller For Sale

[lwg]

I'm switching out my isolator for my dual batteries and decided to go ahead and sell this. It's the standard Intelligent Solenoid with the dual battery controller and accompanied cable. Everything works perfectly.

For those who are wondering why I'm selling it. I'm still a huge fan of this system however it has one very minor flaw, at least in my application. It won't charge the second battery until it's been powered for about 5 minutes. Turns out in my tiny town I can just about drive everywhere in 5-10 minutes thus the second battery is constantly running down. It works perfectly in all other applications including road trips. I essentially just went to a standard "Stinger" 80A solenoid as my isolator now.

I'm looking for $150 for everything shipped.

Not true. See that "ON" button on the lower right of the controller? Push and hold that for 3 seconds - it bypasses the 5 minute timer and the solenoid links the two batteries manually. This charges both batteries at once vice just the starting battery, and links the two batteries for emergency starting/winching power when needed.

Also, if you put your starting battery on a trickle charger/maintainer it will charge both batteries - no need to move the cables over to the second battery or anything

If you decide to upgrade, I recommend using a Cole Hersee 48530 Smart Isolator. Its rated for 200A continuous current (750A Peak), uses less than 1/4 the standby current. Has a Boost button for linking the batteries together, and status light on device + external status wire.

It's made in USA, and certified to SAE J1455 and J1113 + IP65.

Instead of a timer, it uses the sense lines to detect if either of the batteries is above 13.2V (for 2 minutes, as margin), then pairs the batteries for charging.

I've used that before, problem is I'd have to use it each and everytime I drive somewhere. Also I'm not certain how long it keeps them connected but I do believe that once that time has passed it then re-isolates the primary battery for some period of time. I've noticed more than once where the controller showed only the primary battery being charged.

It's just not practical for my application, nothing wrong with it for 95% of folks.

lbrito,
I ended up just going with the Stinger 80A relay. It should be more than adequate for my needs. KISS principles apply here.
