    Swap out Lead Acid with LiPo

    Our 349m should be arriving within 2 or 3 weeks. I have both the gen set and solar panel options checked so I believe I'll be getting the 300w solar panel with Jaboni 30A MPPT controller. According to the manual you can change the battery type to LiPo which is great. However, I'm wondering if I can fit 2 of these batteries in the space the lead battery took up.

    I know the panels will take longer to charge but considering this may work well as we will never go longer than 3 or 4 days off grid and have the generator to charge the batteries completely if / when solar doesn't do it over night. Need to run small electronics at night along with CPAP machine.

    Thanks guys!

    I think the Momentums and Solitudes are pretty much the same... our Solitude (factory solar) came set up for two batteries from the factory. This included vented boxes already mounted. I just slipped the two Battle Borns into them and set the MPPT controller for lithium. The other thing I did was switch the converter/charger to a lithium-compatible model so it would take the BBs to full charge.

    2X on previous comment. The stock converter charge cycle is not designed to work with Lion.

    Check your CPAP manual/website on using batteries. You can significantly reduce the draw if you run them off a 12v source and not use the heated tubes.

    I switched the solar charger (MPPT) to lithium. I am guessing there is also a charger (which you speak of above) that charge batteries when connected to utility, gen or truck but cannot find it. Where or how did you switch to Lithium mode?

    Thanks

    It's called an converter/charger and provides everything 12VDC to the rig (including charging batteries) when on shore power. Unfortunately, the OEM converter/chargers do no have a mode for lithium. They'll charge your LiFePO4 batteries and won't hurt them, but they won't charge all the way. We replaced our OEM converter/charger with a model designed for lithium. The converter/charger is in the space behind the basement wall - usually close to your power distribution panel.

    Ok. We just picked up our 2022 Momentum 351M-R yesterday. It has the factory installed solar package and generator. Finally found how to download app for the Jaboni MPPT programmable charge controller. However, not really sure what all the settings ought to be. When I try to change the battery type, I get a message "Hint" that I need administrator privileges. How do I get admin privileges? I have not found anywhere in the app to change that. The app I have is called SolarApp.

    Thanks,

    Steve

    Click the + and then admin. Password is 135790123. Check with your battery mfg as they will have the recommended settings. Also don't forget to change the battery type from wet/lead acid to LI. I believe this can be done via the app but I did it on the MPPT controller by pressing in the SET button for > 8 seconds, then pressing again until blue light comes on and let it time out.
