12V Battery, HWE 12V 100Ah Lithium Battery 4000+ Cycles Rechargeable Deep Cycle Battery Built-in BMS for RV Camper, Marine, Solar Energy Storage, UPS, and AGM Battery Replacement-2 Pack

The HWE 12V 100Ah Lithium Battery is a rechargeable, deep cycle battery with 4000+ cycles built-in BMS. It is meant for use in RV camper, marine, solar energy storage, UPS, and AGM battery replacement. The battery features a low-temperature cutoff in the BMS, preventing charging when the temperature is below 0℃. It is capable of working with car audio, and normal SLA battery charger or smart charger can be used to charge it. Users can connect any number of batteries in series or parallel, depending on space, with a charging current maxing out at 50A. The battery is not designed to be operated as a cranking battery. Positive reviews indicate customers have converted from AGM batteries to LiFePOs and are pleased with the range, charging efficiency, and extended usage time. One customer used it for their bass boat and paired it with a NOCO 3x10A charger, saving 100 pounds. Another customer used it for backup power for their freezer and worked fine for 24 hours before an error occurred. However, a failed BMS led to a defective product, with the company, Howell Energy, failing to take responsibility or reply to emails in a timely manner. Overall, this product is versatile and efficient, with the potential to improve battery life and range for a variety of applications. However, customers must be cautious of the possibility of receiving a defective product and unreliable customer support.
