Fun Fact: Tucson has never experienced 100-degree weather in March for as long as records have been kept. We are poised to blast through that record this weekend, along with a bunch of other individual day records next week.
Lance updates: With a couple of hiccups, my LiFePO4 battery project went well. I ordered two 100 ah batteries from Amazon. The Lance has a small battery compartment on each side of the trailer, which needed to be modified in order to accommodate the wider SOK batteries. The local auto parts store was happy to take the dead lead acid batteries. I ended up building wood boxes that sit on top of the sliding tray in each of the battery compartments. The sliding tray locks in with a rod and locking outside door, and a strap makes sure that they don't move around.
I bought an Eco-Worthy LiFe PO4 20 amp charger from Amazon to get both batteries fully charged before installing in the Lance, made sure that the batteries fit into my crude wooden boxes, made sure that the wooden boxes fit nicely inside the battery trays of the Lance, and then still managed to make a mistake raising my blood pressure.
The solar charger in the Lance does not have a way to check on the health of each battery, individually. It only shows when both batteries are charged to 100%. Fortunately, the SOK batteries come with an app that allows me to monitor the batteries individually by bluetooth. After everything was installed in the Lance, the app worked perfectly, showing both batteries with full charges. About a week later, I went out to the trailer and could only find one battery on the app. My first thought was somebody stole one of my brand new batteries. A few choice words were muttered. After confirming that both batteries were physically still in their respective battery compartments, I was at a loss for explaining why the second battery wasn't showing up in the app.
I took the solar charger off the wall inside the Lance and couldn't find anything wrong. Then I went to Mr. Google and saw that if one of the SOK batteries isn't being charged for awhile, the built-in operating system shuts itself down into sleep/storage mode. But why wouldn't both batteries be charging? The sun was continuing to blast into the solar panels in the Sonoran Desert. I checked battery one. Nothing wrong with it. I checked battery two. Hmmm, the positive post looks different than the negative post. A washer had hung up when I tightened everything down and wasn't making contact. I took the wires off the positive post, straightened the washers, and tightened everything back down again. Sure enough, the app immediately showed both batteries, and they were both still at 100%.
We are in the middle of our last three sets of guests. Even though the Upper Midwest has experienced record-breaking snow and cold this winter, I'm afraid they aren't going to be ready for the triple digit days that have prematurely arrived. Dave and Ruth spent last weekend here and then spent the week in Joshua Tree after driving there in a rental car. They return today for this weekend. I've known Dave since sixth grade, and he has always lived within a mile of the moderating climate effects of Lake Michigan. He's going to think he's arrived in hell!
