HWE 12V 300Ah Lithium Battery, Deep Cycle LiFePO4 Battery Built-in 100A BMS, Offer 4000~8000 Cycles for RV, Marine, Solar Energy Storage, Golf Car, UPS，and Household Backup Power

The HWE 12V 300Ah Lithium Battery is a deep cycle LiFePO4 battery built with a 100A BMS that offers 4000+ cycles for various applications such as RV, marine, solar energy storage, golf cars, UPS, and household backup power. The battery has a built-in low-temperature cutoff feature that helps to protect it smartly by reducing charging current when the temperature drops below 0°C. It can be connected in any number in series or parallel, depending on space. However, users must note that the charging current should not exceed 50A. Also, it must not be used as a cranking battery for a 250hp marine outboard motor. Users must find the manual or check on the internet to determine if it is suitable for their cart before use. Based on the available reviews, customers have mixed experiences using the product. Some users are impressed with the battery's performance and longevity, such as the customer who converted their Ryobi riding mower from AGM batteries to these and has almost double the range. Others have experienced issues such as receiving defective batteries, one of which looked like a return, not being able to charge after a few months, slow discharge even when powered shut off, and receiving terminal bolts that are too short.
