Wolf Creek 840 Goes Lithium
Let me start by saying that I’m not an RV guru and definitely not an expert on electrical stuff. I have just enough handy skills to be able to use a screwdriver and a wrench. Everything else is usuall...

The AGM batteries (2) that I was using are still working. One of them only holds at 12.8 or less 30 minutes after charging to full. I don’t like to wait until batteries are so fatigued they ruin a trip. A third battery from the same batch I bought in 2016 also began showing signs of failure, so I decided it was time to make the change. I said that I was cheap, not broke! While spending big on batts like Battle Born would be great I just couldn’t do it. We’ll see if I blew my money on unreliable cheap stuff and I regret it. I will be sure to report problems.
The WFCO converter in my Wolf Creek is original equipment. It has been reliable and in use continuously - the camper has always been plugged in to shore power during storage for battery maintenance and portable heat to keep it dry during winter. I am ignorant as to the brand’s reputation. I am keeping the original board as an emergency replacement. It’s a simple switch. I am interested to see how the auto-detect performs in recognizing the LiFePO4 batts. Some people report problems getting it to work.
As far as charging voltage recommendations for LiFePO4, available advice was all over the map. I don’t know whom to believe so I just took the batt company’s recommendation that 14.4-14.6 was adequate. I’ll know soon enough if they get full or not. The main benefit of the upgrade is still a significant increase in useable current storage compared to lead acid with considerably less weight. This also makes us less dependent on a generator. Now I will only carry a genny if we want to operate the ac.
