Chinese battery manufacturer LiTime has unveiled a new lithium iron phosphate (LiFePO4) product, the 12V 320Ah Mini Smart Self-Heating Battery, designed for residential energy storage and off-grid applications.

The battery has a rated capacity of 320 Ah, delivering 4,096 Wh of energy storage and supporting a maximum continuous output power of 2,560 W, according to the company. It also supports 4P4S expansion, allowing systems to scale up to 65.5 kWh of total energy capacity and 40.96 kW of output power.

In terms of durability, the battery is rated for 4,000 cycles at 100% depth of discharge (DOD), 6,000 cycles at 80% DOD, and up to 15,000 cycles at 60% DOD. LiTime provides a five-year warranty, and the battery carries an IP65 ingress protection rating.

The product features an integrated self-heating function that can be managed through the LiTime Bluetooth app, enabling users to switch between regular and energy-efficient heating modes. This allows faster preheating and shorter charging times in cold environments. To enhance safety and longevity, the battery automatically suspends charging when temperatures fall below 0°C and discharging below –20°C, resuming charging once the temperature reaches 5°C or higher.

The battery measures 36.8 cm × 18.9 cm × 25.5 cm and weighs approximately 26 kg. It also incorporates LiTime’s newly developed encrypted Bluetooth connectivity technology, which uses encryption algorithms and password authentication to improve security.

LiTime said the encrypted Bluetooth feature is particularly suited for shared-use or public environments, such as campsites and marinas, where it helps prevent unauthorized access, tracking, or malicious control, while reducing the risk of abnormal power consumption caused by accidental operations.
