KeepKnow 12V 100Ah Mini (Group 24) LiFePO4 Lithium Battery（automatic self-heating）

Heated 12V 100Ah Mini LiFePO4 Battery delivers powerful, long-lasting energy in a compact, lightweight build. Ideal for solar systems, RVs, marine and off-grid use, it provides safe, durable and efficient performance even in harsh low-temperature environments.

The 12.8V 100Ah LiFePO4 Battery comes with an intelligent automatic self-heating system. It activates low-temperature heating when the temperature drops below 32°F (0°C), and stops heating to resume normal charging once the temperature rises above 37.4°F (3°C), ensuring safe operation in cold environments.

Built for endurance with premium Grade A cells delivering up to 4000~15000 deep cycles. Advanced BMS ensures safety, and a modular design allows easy scalability. Perfect for solar storage, RVs, marine, and off-grid power. Backed by a 5-year warranty for complete peace of mind.

Equipped with a built-in 100A BMS, this battery safeguards against low temperatures, overcharge, over-discharge, and overheating, reducing self-discharge and ensuring safety. It delivers reliable performance, extends lifespan, and operates efficiently in temperatures from -4°F to 140°F, even under harsh conditions.

Easily monitor and manage your battery using a smartphone app. Connect instantly to check real-time battery status, track charge and voltage, control discharge, and remotely switch the battery on or off. This smart, intuitive system puts full control of your power in the palm of your hand, ensuring safety, efficiency, and convenience for all your energy needs.

Supports flexible capacity expansion via up to 4S4P configuration for seamless scalability. Delivering a maximum continuous current of 400A, it supports up to 20.48kW load power and 20.48kWh total energy, ensuring reliable performance and adaptability for residential, RV and off-grid energy storage needs.

Weighing just 20.94 lbs, about one-third the weight of traditional lead-acid batteries, compact and lightweight for easy carrying, installation, and handling, while improving portability, saving space, and reducing strain during setup and transport.

Three flexible charging options: 14.6V 20A LiFePO4 charger for a full charge in about 5 hours; 600W or higher solar panel with MPPT controller for fast charging in about 2 hours; generator paired with a 40A DC-DC charger for charging in about 2.5 hours.

Delivers reliable, high-efficiency energy for solar systems, RVs, and off-grid setups. With an extended cycle life, it provides the perfect solution for dependable energy storage and backup power whenever you need it.

Use batteries with matching brand, type, voltage, capacity, and BMS. Operate within safe temperature ranges. Not for golf carts or car starting. Smart BMS ensures protection and longevity.
