Built-In Heating, Reliable In Cold Climates.
The Temgo 12V 300Ah LiFePO4 Battery features an advanced self-heating system for reliable low-temperature charging. It automatically activates heating when charging below 32°F (0°C), and stops heating once the temperature exceeds 41°F (5°C) to resume normal charging—protecting battery health and boosting charging efficiency. With a low-temperature discharge cut-off at -20℃ ± 4°C (-4°F ± 7.2°F), it ensures safe, consistent power output even in extreme cold, eliminating cold-weather charging and usage worries.


Clear Metrics, Effortless Monitoring
Check remaining energy via the TEMGO App before operating power-hungry devices or planning overnight power consumption. Bluetooth provides real-time SOC, voltage, current and temperature readings, and the built-in LCD touchscreen allows direct data viewing on the battery unit. Remotely monitor battery status and arrange energy consumption reasonably, and you will never need to open the storage compartment.


Optimized Output, Greater Usable Energy.
Traditional lead-acid batteries only deliver a fraction of their rated capacity, cutting your runtime short. Our TEMGO LiFePO4 battery supports 100% DOD, unlocking significantly more usable energy within the same battery footprint. Power your equipment for much longer, without adding extra batteries to your system.


Large Capacity, Manage Heavy Loads
Boasting a 12V 300Ah capacity, this Temgo self-heating battery delivers ample stored energy to sustain heavy continuous loads. An upgraded 200A BMS provides up to 2560W continuous power for trolling motors, RV appliances and off-grid hardware. Designed for broad usability, it works reliably for year-round RV living, marine outings, cold-climate solar installations and essential off-grid power needs.


Scalable Design, Expand On Demand.
One battery can power your travel trailer today, but larger cabins or extended solar arrays need extra energy storage in the future. This TEMGO LiFePO4 allows up to 4-series and 4-parallel connection, creating a 51.2V, 61.44kWh energy system at maximum. Start with a basic 12V system and expand step by step, without replacing your current battery bank.


Flexible Input, Multiple Charge Sources
Grid power isn’t always within reach, whether you’re camping off-grid or running home energy storage. This LiFePO4 battery can recharge through an AC charger, solar system, or generator paired with a 12V AC-DC charger. Harvest solar energy during the day for RV and household use, or use an AC charger or generator to top up power when sunlight is lacking.
