Question:
We have a well equipped 2003 Teton Hoimes 5th wheel. What is required to change up from AGM deep cycle batteries to LiPo? We have a Freedom 458 Combi not sure which model. It has electrical problems now, but I think it is due to the fact that I temporarily replaced the 4 group 31 deep with 2 - 24 series deep cycle. Problem is that none of the 110 outlets work, but A?C works, all breakers are on and GFCI are working. Any advice is appreciated.

Hey Alvin, thanks for the information. We've got a couple of options to upgrade your AGM batteries to LiFePo4 ones. I have listed them below:
Go Power Sun Cycle Advanced Lithium RV Battery - LiFePo4 - Bluetooth - Group 24 - 12V - 100 Amp Hour item # GP99QR
Go Power Lithium RV Battery - Deep Cycle - LiFePO4 - Group 31 - 12V - 100 Amp Hour item # 34282738
You're definitely going to need to replace your Freedom 458 Inverter Charger as it's not rated for Lithium batteries. I recommend the Go Power Industrial Pure Sine Wave Inverter Charger - 3,000 Watts - 100 Amps - 12V item # 34275013. The integrated transfer switch will automatically change to shore power when you connect, and because it is a pure sine wave inverter, you can run things like a TV or computer without there being distortion. It will also charge your Lithium batteries at the correct voltage.
Have you had an electrician or an RV tech look at your outlets and see what the issue is?
