The Sungoldpower 24V 100Ah LiFePO4 battery is a deep-cycle lithium battery with built-in Bluetooth monitoring, an LCD screen, self-heating for cold weather, and an IP65 rating. It uses automotive-grade cells rated for 4000+ cycles and a 100A BMS. It suits off-grid solar, RV, and marine users who need a durable 24V bank and want to monitor state of charge from a phone. Compared with basic 24V lithium batteries, it adds cold-weather heating and app monitoring, but it is heavier and bulkier than smaller 12V units.

Owners appreciate the built-in Bluetooth monitoring and self-heating for cold climates, and many report reliable performance in solar and RV setups. Some mention the weight and bulk make installation harder, and a few note the app could be more stable.
It uses automotive-grade Grade A cells certified to UL1973. The cells are rated for more than 4000 deep cycles and a lifetime of more than 10 years.
A built-in 100A BMS protects the battery from overcharging, over-discharging, over-current, short circuits and high temperature. An LCD display shows the battery voltage and state of charge (SOC). The Bluetooth module shows real-time battery information on a mobile device.
The self-heating function turns on automatically when the battery's core temperature drops 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. Batteries can be connected in parallel for larger capacity in RV, van, solar and camping setups.
