Switching to lithium house batteries on 2006 Mountain Aire.

[anchovy225]

Hello all. I recently purchased a beautiful 1 owner mountain aire.

I purchased 4 Battleborn 12v batteries to replace the 4-6v batteries. I have also purchased a Victron DC/DC charger to keep the lithium batteries from killing my alternator and receive a proper charge. It already has a new magnum inverter/charger and controller with a lithium charge profile so I’m not worried about it charging from that end.

I’ve been doing lots of reading and trying to educate myself on how this bird system works.

But what I can’t seem to figure out is where to install the DC/DC charger.

If you’ve done this conversation please chime in I don’t want to screw anything up.

Put the DC to DC input on the wire on chassis side of the bird, output to the bird. It is best to change the Bird to the New Lithium version, it has the logic built into it so if you have the black logic box you can do away with it, this will keep your batteries to the right level.

Battleborn's have great reviews

Well, not to hijack a thread, but how do I handle the 6 Volt tap on the Mountain Aire? The last coach and this newer (08) version have "tap" in the center between the two 6V sections. The schematic shows that several areas in the bed room use 6 Volts.

I don't know why and I don't know how to provide six volts to those sections. I am looking at going to Lithium, but don't know what to do about this.

Anybody have any insight?

Your MA uses the 6v power for the "low" lights on the halogen puck lights that are all over your coach. Since all those puck lights use something over 50 amps when on, I swapped them all to LEDs, now with all those lights on I am just under 5 amps. The only niggle is, no "low" setting. I eliminated the 6v jumper across the batteries.

Just take the 6v tap and zip tie it to your main bundle and make sure it is labeled well.

STRich, thanks for that. If I just hook them up, they will work too brightly, but that's OK for now.
