We're going to educate ourselves more on the inverter/converter/charger issues. But definitely moving forward with a new battery. Thanks so much!Change to LiFePO4 battery for Freedom Express UltraLiteWe have a 2021Freedom Express UltraLite 231RBDS and need to replace the LA battery after a couple of seasons. Would like to go with Lithium (LiFeP04), but it looks like our current Controller/Inverter (WFCO model WF-8955) doesn't have a "lithium" switch or option. Can anyone with a similar Freedom Express who has made this transition share their experience? Did you change out your Controller? Or was the original Controller able to charge it but not quite to 100%? We've read that they can sometimes charge up to ~80% without the Lithium switch. Just trying to get more consistent power without damaging something. Thanks for your help!
