Help - Switching to lithium Delta 252RL

[MikeIam]

I just picked up a Delta 252RL and I want to use a lithium battery. Other than the solar charge controller, do I need to change a setting on anything else? My concern is charging when connected to a pedestal or generator?

You will need to check your converter make / model. Some have a switch that needs set to the battery type and some are auto detect. We have a 310 RL, so it is equipped with a switch that needs set accordingly.

Thank you. I thought so but, I have no ideal where the converter is. I found the A/C breakers and the DC fuses. I know where the solar charger is. I have no idea where to find the converter.

You might find some helpful information that allows you to indentify your converter.
Ours is part of the distribution panel and has a very tiny switch near the bottom that allows for battery type selection.
If its location isn’t obvious to you, give the A -Team a call with your VIN and I am confident that they can steer you to it.

MikeIam,

I too switched to lithium on our '24 385FL. The converter is built into the power distribution panel and I pulled the cover on the panel to access the switch that Bryan talks about above.
Switched it to Li and works great. I also set the parameters in the Renogy solar controller to match the lithium battery's specs.

Hope this helps,
Bruce

Once you change to lithium, your 4 LED battery gauge is worthless. Lithium will hold a higher voltage down to about 10% of battery remaining. You will see 4 LED showing 100% charge, until it is waaaay too late. You need to install a battery shunt, which will show you the exact battery level and the amount of amps coming in & out of the battery.

The Victron shunt is by far the gold standard. Install will take about 20 mins.
