I finally got around to installing my lithium battery today. The Power Dynamics converter needs to be witched from flooded lead acid to lithium on a 2025 340RL; it is not automatic like some converters. In any case, i read how it could be a pain in the hindside on some models. On the 2025 340RL, it was piece of cake, 10 15 minute job. In my model, the bottom shelf in the coffee station is a false floor held in by four screws.

Remove the four screws and remove the floor/shelf.

To the right of the plenum is the converter.
On the converter you can see a pin hole and a larger hole. You should have a pin taped to the back of the converter (mine was behind some yellow tape and I reaffixed it with the white tape as seen in the pic). Remove it an place it in the pin hole and hold. The opening you see to the right of the pin hole is the indicator light informing you what charging mode you are in or if it is straight line voltage. Mine had a label on it informing us that when the light turns blue, it is in lithium charging mode. Just press and hold the key with light pressure in the pinhole until the light turns blue. The light will not stay on after you remove the pin after changing the charging mode.

Put it back back together and your done. Easy peasey on the 2025 340RL.
