12V 300Ah Lithium Battery with 200A BMS

Worried about overloads, excessive current, or unexpected battery damage when running high-power appliances? Temgo’s LiFePO4 battery features an upgraded 200A BMS that continuously monitors battery conditions and provides comprehensive protection against overvoltage, overcurrent, overcharging, over-discharging, short circuits, and overheating. By automatically responding to abnormal conditions, the BMS helps protect the battery from potential damage and ensures safer, more stable power for your home, RV, and off-grid applications.

1/3 the Weight with Same Capacity

Why carry the extra weight when you don't have to? Traditional lead-acid batteries can be heavy, bulky, and limited in usable power and service life. TEMGO LiFePO4 gives you the same capacity at just 1/3 the weight, so you can enjoy easier handling, simpler installation, and greater freedom without giving up the power you need. With 100% DOD, 5000+ cycles, up to 10 years of battery life, and built-in BMS protection, TEMGO delivers more usable energy and long-term reliability in a lighter package.

Smartphone APP Monitoring

Tired of guessing how much power is left or worrying about unexpected battery issues? With Temgo’s smart monitoring system, you can check your battery’s operating status at a glance instead of relying on guesswork. Simply scan the onboard QR code for quick Bluetooth pairing, then view voltage, current, remaining capacity, and temperature in real time on the built-in touchscreen or Temgo App. Stay informed wherever you are and spot low power, overload, overheating, or other abnormal conditions early, so you can manage your power with greater confidence.

Flexible Capacity Expansion

Start with the capacity you need and expand as your home power demands grow. Temgo’s 12 volt 300Ah LiFePO4 battery supports up to 4S4P connections, allowing multiple batteries to be combined for greater energy storage and power output. Build your home energy system step by step and enjoy the flexibility to scale up for refrigerators, washing machines, air conditioners, and other high-power household appliances. Whether you need reliable backup power or additional energy storage for your home, Temgo makes it easy to build a system that grows with your needs.
