Temgo 12V 300Ah Bluetooth Self-Heating Lithium Battery for Trolling Motors, RVs, Home Backup, Off-grid CA

Built-In 200A BMS for Enhanced Battery Protection

A large-capacity battery needs dependable protection, especially when it is connected to high-power equipment. Temgo’s 12V 300Ah LiFePO4 battery uses an upgraded 200A BMS to monitor battery conditions during both charging and discharging. The system is designed to help protect against overcharging, over-discharging, overcurrent, overvoltage, short circuits, and excessive temperature. When abnormal conditions occur, the BMS can automatically activate the appropriate protection, helping maintain safer and more stable battery operation under demanding loads.

300Ah Capacity Without the Extra Weight

More stored energy does not have to mean a heavier power system. Temgo’s LiFePO4 chemistry delivers 12V 300Ah capacity while weighing approximately one-third as much as a comparable lead-acid battery. The reduced weight makes transportation and installation easier, particularly where available space and payload are limited. With 100% depth of discharge, 5000+ cycles, and up to 10 years of expected service life, the battery is designed to provide high usable capacity over many years of regular use.

See Battery Data in Real Time

Battery management becomes more convenient when key operating information is always within reach. Temgo combines a built-in LCD touchscreen with Bluetooth connectivity, allowing you to check battery status directly from the unit or through the Temgo App. Once paired by scanning the onboard QR code, you can view important information such as voltage, current, temperature, and remaining capacity in real time. This gives you a clearer picture of how the battery is performing and makes it easier to manage energy consumption before the battery reaches a low-power or abnormal condition.

Scale Up Your Battery Bank with 4S4P Support

Your energy storage requirements may grow over time, so Temgo gives you room to expand. The 12V 300Ah battery supports battery-bank configurations of up to 4S4P, allowing multiple units to be combined for increased storage capacity and higher system voltage. Instead of building a large battery bank from day one, you can start with the capacity you currently need and expand the system later. This flexible configuration makes it easier to adapt your energy storage setup as your power requirements increase.

Multiple Ways to Keep the Battery Charged

Access to electricity can vary from one location to another, which is why flexible charging options are important. Temgo’s 12V 300Ah battery can be recharged using solar power, an AC charger, or a generator. Connect it to a solar system when renewable energy is available, use AC charging when grid electricity is convenient, or turn to a generator when additional charging support is required. Having several charging options makes it easier to maintain your energy supply in both connected and independent power systems.

One Battery for RV, Marine, Home Backup and Off-Grid Power

With its combination of high capacity, strong continuous output, long service life, and flexible charging options, the Temgo 12V 300Ah LiFePO4 battery can fit into a wide range of power systems. Its 3840Wh capacity and up to 2560W continuous output make it suitable for extended energy use in RVs, boats, fishing setups, home backup systems, and off-grid solar installations. Depending on your system design, it can provide dependable power for refrigerators, lighting, electronics, and other essential equipment, making it a versatile energy-storage solution for both everyday use and situations where reliable backup power matters most.
