Key Features
- Extended Lifespan: Offers approximately 2000 cycles at 80% Depth of Discharge (DOD), providing a lifespan up to 4 times longer than conventional lead-acid batteries.
- High Power Output: Delivers a maximum of 2176 Wh power output, which is 2 to 3 times more powerful compared to most lead-acid batteries of the same size.
- Superior Discharging Performance: Provides a maximum continuous discharge current of 125Ah, capable of powering most home appliances. Stable capacity and performance are maintained even in extreme temperatures ranging from -4°F (-20°C) to 140°F (60°C).
- Enhanced Safety and Reliability: Equipped with a built-in Battery Management System (BMS) that provides protection against over-charge, over-discharge, over-current, high temperatures, and short-circuiting. The fully-sealed housing prevents acid leakage and corrosion, ensuring minimal maintenance.
- Lightweight Design: Approximately 50% lighter than comparable lead-acid batteries, making it easier to transport and install while delivering more power.
Setup and Installation
Proper setup is crucial for the optimal performance and longevity of your Renogy LiFePO4 battery. While these batteries are often marketed as "drop-in replacements," it is important to understand that direct connection to certain charging sources, such as an alternator without proper regulation, can damage the battery.
Important Considerations:
- Charging Compatibility: Ensure your existing RV charge controller or solar charge controller is compatible with lithium batteries. Many older controllers are not designed for LiFePO4 charging profiles.
- Alternator Charging: Do not connect the battery directly to an alternator without a suitable DC-to-DC charger. For this approach, consider using a dedicated DC-to-DC controller, such as Renogy's 20 AMP DC to DC controller, to regulate the charging current and voltage.
- Cable Lugs: The battery terminals typically require 1/2-inch lugs. Ensure your cables are appropriately sized and terminated for secure connections.

Operating Instructions
The Renogy LiFePO4 battery is designed for efficient and safe operation across various applications. Its built-in Battery Management System (BMS) actively monitors and protects the battery during use.
General Operation:
- Temperature Range: The battery operates effectively in a wide temperature range from -4°F (-20°C) to 140°F (60°C).
- Discharge Current: The battery supports a maximum continuous discharge current of 125 Amperes, suitable for a variety of appliances.
- Charging Voltage: The BMS is designed to accept charging and will suspend charging when full, resuming once a certain amount of discharge occurs. A common recommended charging voltage is 14.4V (±0.2V).

Maintenance
The Renogy 12V 170Ah LiFePO4 battery is a sealed, maintenance-free unit, meaning it does not require regular watering or acid checks like traditional lead-acid batteries. However, following best practices can further extend its already impressive lifespan.
Best Practices for Longevity:
- Depth of Discharge (DOD): For maximum lifespan, avoid consistently discharging the battery below 25% (keeping DOD no more than 75%).
- Charging Amperage: Keep charge amps below 50 Amperes, or ideally around 40 Amperes, to promote longer battery life.
- Storage: If storing the battery for extended periods, ensure it is charged to an appropriate level (e.g., 50-80% state of charge) and stored in a cool, dry place.
Troubleshooting
The built-in Battery Management System (BMS) in your Renogy LiFePO4 battery is designed to protect it from various conditions. If the battery appears to be malfunctioning or not performing as expected, the BMS may have activated a protection mode.
Common Issues and BMS Protections:
- No Output/Charging: The BMS may have activated protection due to:
- Over-charge: If the charging voltage or current exceeds safe limits.
- Over-discharge: If the battery voltage drops too low.
- Over-current: If the load draws too much current.
- Short-circuit: If a direct short occurs across the terminals.
- Low Temperature Charging Shutoff: The BMS includes a critical low-temperature charging shutoff. LiFePO4 cells can be damaged if charged below 32°F (0°C). If the battery is in a cold environment and not accepting a charge, this protection may be active. Allow the battery to warm up before attempting to charge.
- High Temperature Protection: If the battery's internal temperature exceeds safe operating limits, the BMS will activate protection to prevent thermal damage. Allow the battery to cool down.
