RE: Are the new WFCO's as bad as the old ones?

Our WFCO in our 2018 Escape camper decided to charge our AGM's at 20.3 volts destroying them. After getting our new SiO2 batteries we merely disabled the charger portion and only charged with our rooftop solar for the next two years. Worked great. I received a different WFCO to replace the bad WFCO charger, installed it, but never used it. We sold the trailer last December. We now have a 2026 Bigfoot 25RQ with a Progressive Dynamics 45 amp charger. By adding their "Charge Wizard" it charges our two new 100 ah SOK LFP batteries just fine, but it's also disconnected in favor of the 160 watt rooftop solar and a 100 watt portable. For the past two weeks in Arizona our SOK's have been topped off most days, but with excess ah's not topping off a day or two is just fine. The lowest we've been so far is 78% SOC. Over two years ago when our WFCO charged at 20.3 volts I found a couple others who had the same experience with their WFCO's. I'm glad our new camper has a Progressive Dynamics charger. Enjoy, Perry

RE: Lithium for dummies: need advice in simple terms

Did you get the SOKs with heaters?The following is from SOK's web site: SK12V206H designed for cold weather using! Can safely charge at temperatures down to -20°C (-4°F) by a standard charger or solar charger. The heater pads which draws power from the charger itself,battery cells no power lost. The Sok heater only works when you are connected to a power source, i.e. plugged in at a campground, or during the day when you have adequate solar. If you're boondocking, when we would want a heater, they don't heat at night when it gets cold. Enjoy, Perry
