Lithium Batteries
Just downsized from a Class A DP to a Class B+. I got the residential fridge in the new motorhome so power when off the grid is going to be more of an issue that it was before. I’ve been looking at ...

Ok, well this subject took off since I started it. Hadn’t been back in a while so I read some of the newer replies but not all. So I’ll get on to my next question. I went ahead and bought two Battle Born 100AH lithium batteries. $2100 for both if anybody cares. There were some cheaper alternatives out there, but the Battle Born factory and factory sales center is a few miles down the road so I opted to pay a couple of extra bucks to have them close by. And they had some mock up batteries at the office so I was able to go down there and use their mock ups to make sure they would fit in my battery compartment. They fit.
So I found out my converter actually supports Lithium batteries with just the flip of a switch. So once I install the batteries just flip the switch and we’re good. But, the lady who I bought them from, said that since my RV has a 230 amp alternator and that need to install a DC to DC charger to bring it it down to 100 amps for charging the battery. She seemed to know what she was talking about but I don’t know her background so I thought I’d ask here. Anybody else that switched to lithium install the DC to DC charger? I know the motorhome is already set up to charge the house batteries from the alternator but I’m assuming the lead acid batteries don’t need this DC to DC charger and can take all the power from the alternator? I’m not an electrician so I’m not sure how this stuff all works.
