Temgo 12V 300Ah Self-Heating Lithium Battery – Unstoppable All-Season High Capacity
Conquer any climate with the Temgo 12V 300Ah Self-Heating LiFePO4 Battery. This exceptional battery combines a colossal 300Ah capacity with an intelligent self-heating system, advanced app monitoring, and an intuitive touch screen. Housed in a robust IP65 waterproof casing, it’s the ultimate all-weather power solution for serious adventurers, critical off-grid systems, and anyone who demands uninterrupted power, even in the coldest conditions.
Intelligent Self-Heating for Optimal Cold Weather Charging and Use
The Temgo 12V 300Ah LiFePO4 Battery features an advanced self-heating system, ensuring reliable performance during low-temperature heating for charging. The self-heating starts automatically when charging is attempted at ambient temperatures below 32°F (0°C). Once the battery's internal temperature reaches above 41°F (5°C), the self-heating stops, and it charges normally, safeguarding battery health and optimizing charge efficiency. For discharge, it includes a low-temperature cut-off at -20℃ ± 4°C (-4°F ± 7.2°F).
Smart Connectivity, Enduring Build, and Effortless Monitoring
Stay connected to your power source with the app monitor for your smartphone. This battery provides 100% State of Charge (SOC) and 100% Depth of Discharge (DOD), allowing you to use its full capacity. Engineered for longevity, it delivers 2000-5000 cycles and a 10-year service life. Its robust, IP65 level waterproof design is completely maintenance-free and vibration-resistant. This high-capacity self-heating model weighs 64.92 lbs and features the convenient LCD touch screen and app monitor for easy system management.
Total System Visibility with Intuitive 3-Page LCD Touch Display
The clear LCD touch screen offers three pages of monitoring modes for a comprehensive overview of your battery’s status:
- Page 1: Provides a real-time display of battery current, voltage, temperature, etc.
- Page 2: Allows you to toggle controllable charge and discharge on/off modes directly from the screen.
- Page 3: Displays the voltage difference of the internal battery cells, crucial for monitoring battery health.
Versatile High-Capacity Energy for All Your Demanding Needs
The Temgo 12V 300Ah self-heating battery is perfectly engineered for a multitude of applications, especially where cold weather is a factor. It’s an outstanding choice for year-round RV living, extended boat and fishing trips in any season, large-scale solar and wind power installations in cooler climates, critical off-grid applications, and comfortable camping no matter the temperature.
Consistent High Performance, Rigorously Validated
Experience superior performance with this Temgo LiFePO4 battery, backed by comprehensive testing conducted in October 2022. Performance metrics, illustrated by the different rate discharge curve (at 25°C), different temperature discharge curve (at 0.5C), and state of charge curve (at 0.5C, 25°C), confirm its reliable and stable output across a range of discharge rates and temperatures, ensuring dependable power for all your needs.
