Just learned the battery is supposed to arrive on Friday, the day after the US Thanksgiving holiday. I’m pretty excited! I also ordered a Bluetooth dongle that will tell me the wattage/voltage and amount of charge on the battery. I have them on my other systems, it’s nice to be able to stand inside of the SkyCastle and see the state of charge of my 2 other battery banks. This dongle is really designed to use on cars, but years ago I discovered they work great on any 12 volt battery no matter the chemistry. I noticed the listing on Amazon now says it can be used with LiFePO4 batteries. I use an app that shows up to 4 separate dongles.
