ECO-WORTHY 24V 100AH LiFePO4 Lithium Battery $218.45 + Free S&H

ECO-WORTHY 24V 100AH LiFePO4 Lithium Battery, Deep Cycles Rechargeable Battery with Low-Tem Protection, Max. 2560W for Off-Grid. I haven't seen 24V deals in a while, and happy to have found this as my home setup is 24V. I already own 4 of these, but without Bluetooth and paid ~$330/each a year ago. Even today this is about $100 cheaper than what you can find anywhere else. $248.45 - $30 coupon (CDUS30) = $218.45 before taxes.
