2007 T@B Dutchman Battery Change

Hi, I have an older T@B and both Lead batteries are not charging over 10V. I have read that these batteries feed each other and that is why there are two. I am considering getting 1 Lithium 

Power Queen 12V 100Ah LiFePO4 Battery BCI Group 24 Lithium Battery, Deep Cycle Battery with 100A BMS.

I don't have solar so I am wondering is this a simple plug & play or will I need to make any power conversions of any kind?

    More than likely your converter is not designed for charging LiFePO4 batteries. It should be able to partially charge the battery. In this case a portable lithium charger can be used to charge the battery fully.

    … or if you have solar that will top it off.

    @LuckyLou Perfect time to change out to lithium.  The converter is designed to only charge lead acid batteries.  It will charge lithium to about 80%.  As elbolillo noted, a portable charger is necessary as lithium batteries must be occasionally charged to 100% for cell balancing, though should not be kept at 100% for long periods of time.  If the Power Queen does not have a viewable BMS gauge, you will need to measure state of charge.  Voltage is not a good indicator.
