LOSSIGY 12V 400AH Lifepo4 Battery, 5120Wh Deep Cycle Lithium with 250A BMS, 3200W Load Max Continuously, Perfect for Solar System, RV, Marine, Off-Gird

The LOSSIGY 12V 400AH Lifepo4 Battery with 5120Wh Deep Cycle Lithium and 250A BMS is a top-quality battery that is perfect for solar systems, RVs, marine applications and off-grid power systems. The battery is capable of providing 3200W of continuous load max. As per the customer reviews, this lightweight and powerful battery is designed to last long and is an excellent replacement for the heavy traditional SLA batteries. The battery's operating temperature range is between 32℉--113℉ for charging, and -4℉--140℉ for discharge. Furthermore, the low temperature cut-off while charging is 32°F, and while discharging, it is -4°F. The battery weighs 100 pounds, and the length of the attached copper core wires is 30cm (11.81inch). The battery can be charged via a 12V car battery charger, but the manufacturer recommends using a lithium battery charger to maintain the battery's life cycle and keep it in a fully saturated state. In case of a warranty problem, some customers have faced difficulties in getting a response from the company via email. Also, the battery does not have cold weather protection for charging, so below-freezing temperatures can hamper charging. Despite this, the product has received positive reviews, with customers saying that it is an excellent battery that performs well and provides a long-lasting charge.
