$668 for ECO-WORTHY 48V 100Ah LiFePO4 Lithium Battery with Bluetooth

AliExpress is offering the ECO-WORTHY 48V 100Ah LiFePO4 Lithium Battery for $668, with a $70 discount when you apply the coupon at checkout. The battery features a capacity of 5120Wh, UL certifications, Bluetooth, WiFi, and an app monitor, making it suitable for home solar, off-grid, RV, or whole-house backup uses.

This price reflects a significant discount from the original retail, and the availability from a US warehouse adds convenience. The coupon is required for the discount, which could be applied manually during checkout. The product is highly rated with UL certificates and a 10-year warranty, adding to its value.

However, the deal's score is moderated by the moderate view count and the fact that the price is relatively stable, with slight variations possibly due to currency exchange rates. Still, this is a notable deal for a high-quality lithium battery at this price point.
