High-Capacity LiFePO4 Battery for Reliable RV and Marine Power
For outdoor sports, RV camping, and off-grid solar users, the Temgo 12V (12.8V) 300Ah LiFePO4 battery provides long-lasting power for demanding deep-cycle applications. This high-capacity LiFePO4 battery can solve a series of problems such as insufficient battery life, heavy batteries, high safety risks, and high maintenance costs. It has a lightweight design of 58.4 LBs, 5000+ cycle life, and intelligent monitoring functions. The Bluetooth connection application and the battery's external LCD screen provide real-time information and control.
Deep Cycle Performance
Temgo LiFePO4 batteries feature high-density cells that maintain a stable voltage at loads from 0.2C, ensuring smooth operation of equipment such as boat trolling motors or RVs without power sags. Its 100% Depth of Discharge (DOD) lets you fully utilize the 300Ah capacity without damaging the battery, solving the problem of insufficient battery life during long RV trips or long-distance fishing.
This LiFePO4 battery has a longer service life of more than 5000 full depth of discharge cycles at 77°F (25°C), which can last for 3-5 years under normal use (depending on the environment and method of use). Compared with lead-acid batteries that typically only last 200-500 cycles, it can save you thousands of dollars in replacement costs. The deep cycle service life helps you minimize its maintenance and downtime.
To extend the battery life, the optimal temperature for long-term storage is 50°F (10°C) to 95°F (35°C). If not in use for a long time, it is best to store the battery at 50% charge and recharge it every three months.
Smart Battery Management System (BMS) Ensures Safety
Under harsh environmental conditions such as sailing or off-roading, it is inevitable to worry about the safety of battery use. The Temgo 12V (12.8V) 300Ah battery is equipped with a 200A smart battery management system (BMS) to prevent safety issues such as overcharging, over-discharging, overcurrent, short circuit and overtemperature. The BMS also supports battery balancing to ensure that each battery cell always maintains the optimal voltage for stable performance and longer life.
Its low temperature cut-off function can suspend charging below 32°F ± 7.2°F (0°C ± 4°C) and suspend discharging below -4°F ± 7.2°F (–20°C ± 4°C), protecting the chemical properties of the battery cells and further extending their service life.
At the same time, the Temgo 12V (12.8V) 300Ah battery has a fully sealed housing with IP65 protection level, which is dust-proof, waterproof and shock-proof. This design ensures that it can still maintain reliability in harsh environments and avoid the risk of battery leakage or damage.
Real-Time Data Control Through LCD Screen
The built-in LCD screen provides a user-friendly interface with three dedicated pages:
1. Real-time dashboard: Displays voltage, current, temperature and state of charge (SOC) for instant monitoring.
2. Control and status: Switch between charge/discharge modes, view cycle count and BMS status.
3. Battery voltage balancing: Track the voltage of each battery cell to detect imbalance early and prevent battery performance degradation.
For RV campers, SOC display helps plan appliance use and avoid running out of power on the road, while battery voltage monitoring meets their needs for convenient and reliable battery data information insights.
Integrated Bluetooth Connectivity and APP Management
Temgo 12V (12.8V) 300Ah supports Bluetooth connectivity to the Temgo app, allowing you to keep track of battery performance at all times. Features include:
1. Real-time monitoring indicators: View battery status (SOC), depth of discharge (DOD), total battery pack voltage, current consumption and power consumption in real time.
2. Remote control: Enable or disable charging, discharging, battery balancing or protection mode through your phone.
For RV and van campers, this app allows you to view battery charge (SOC) at camp, plan electrical appliance use, and ensure sufficient power. For boaters, the power of the trolling motor can be monitored through the steering gear, ensuring safe navigation without accessing the battery compartment. For solar energy storage users, remote control allows you to disable the discharge function when the sun is most abundant, thereby maximizing charging efficiency.
How to use:
a. Download the "Temgo" app from Google Play or App Store.
b. Enable Bluetooth and positioning functions on your phone.
c. Open the app, select your battery, and click "Connect".
Temgo 12V 300Ah Batteries Support Variety Of Deep-Cycle Applications
