271 Ah upgrade

For our use in the Northern U.S., 2-100 ah lithium batteries and 4-100 watt solar panels is a bit more than what we need. Spent a couple months traveling to Alaska and back last year, and didn't need to plug in the entire trip. We didn't have a generator. The batteries didn't charge from the truck either, as I have that wire disconnected. We did plug in a couple nights at campgrounds to run the a/c when it was too hot for us. Our typical daily power usage: - watch tv for 2-3 hours at night - lights - water pump for showers and stuff - electric compressor fridge - listen to music for an hour or so in the morning - 3 or 4 cups coffee Keurig on the inverter every morning - wife dries hair on the inverter every morning. Typically the batteries are at 60 - 70% in the morning before the solar starts charging them back up. If its sunny, the batteries are 100% by noon or 1PM. If it's cloudy, 5 or 6pm they are back to 100%

Everyones power needs is different. For me in the winter the furnace is the biggest draw and in the summer the fantastic fan is.

Currently I have a mere 136W of solar on the roof (actual ~100W output) and in the summer months my battery is full sometime between noon and 2PM.

For me it was time to replace the existing #27 FLA and instead of getting another FLA I went with a Battleborn battery. (greater AH, less weight and 3x the cycle life)

While the 100AH battery I currently have will fit my needs the DIY 271 project looks interesting and fun and so why not? (cause I can)

Maybe I won't have to carry the generator as a backup anymore?
