Hi, I recently built and installed a new LiFePO4 560AH battery. Total cost under $1k. Prices for LiFePO4 batteries are becoming dirt cheap for the DIY installation. For those interested I have added a post about the process on my blog: https://svjohannarose.blogspot.com/2021/06/adding-new-lifepo4-to-house-battery.html
With a new inverter and solar installation, this has become a game changer. - Paul E. 1981 C&C Landfall 38 S/V Johanna Rose Fort Walton Beach, FL http://svjohannarose.blogspot.com/
