This is a four-pack of 12V 100Ah LiFePO4 deep-cycle batteries built with automotive-grade cells rated for 4000+ cycles and a 10-year lifespan. Each battery has a built-in 100A BMS, an LCD screen showing voltage and state of charge, Bluetooth monitoring, and automatic self-heating below 33.8°F. It suits off-grid solar, RV, and marine setups that need a large, maintenance-free bank with remote monitoring. Compared with basic lithium batteries, it adds Bluetooth and self-heating; compared with premium brands, it offers similar core specs at a lower cost but with less proven long-term reliability.

This is a set of four 12V 100Ah LiFePO4 deep cycle lithium batteries. The cells are automotive-grade and carry UL1973. They are rated for 4000+ deep cycles and a lifetime of more than 10 years, and the battery has a 5-year warranty.
A built-in 100A BMS protects against overcharging, over-discharging, over-current, short circuits and high temperature. An LCD display shows battery voltage and state of charge. A Bluetooth module lets you monitor real-time battery information on a mobile device.
A self-heating function starts automatically when the battery's core temperature falls below 33.8 °F (1 °C). It stops when the temperature reaches 42.8 °F (6 °C). This lets the battery charge in cold weather.
