Introduction
This manual provides essential information for the safe and efficient use of your Redodo 12V 280Ah LiFePO4 Lithium Battery. Please read it thoroughly before installation and operation.
- Low-Temp Cutoff for Cold Weather: Built-in sensor stops charging below 0°C/32°F and resumes automatically above it. Discharge is possible down to -20°C/-4°F, ensuring safe operation in various conditions.
- Upgraded BMS with Full Protection: Features a 200A Battery Management System (BMS) with 8 safeguards: overcharge, over-discharge, over-current, overheating, short circuit, dust, water, and salt spray protection.
- High Capacity & Expandable: Provides 3584Wh per battery. Supports up to 4 batteries in series and 4 in parallel, allowing for a maximum configuration of 4S4P (48V 1120Ah, 57.34kWh total).
- Long Lifespan & Grade A Cells: Utilizes EV-grade LiFePO4 cells, offering 4000+ cycles at 100% Depth of Discharge (DOD) and an estimated 10-year service life. Features a low 3% monthly self-discharge rate.
- Easy Charging: Compatible with various charging methods, including an optimal 14.6V 56A LiFePO4 battery charger, a solar panel (≥1200W) with controller, or a 56A DC to DC charger and a generator.
Setup

Maintenance
Proper maintenance ensures the longevity and performance of your Redodo LiFePO4 battery.
Charging
The battery can be charged using a 14.6V 56A LiFePO4 battery charger, solar panels (≥1200W) with a compatible controller, or a 56A DC to DC charger with a generator. Always use chargers specifically designed for LiFePO4 batteries.

Storage
For long-term storage, ensure the battery is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place away from direct sunlight and extreme temperatures. The low self-discharge rate of 3% per month helps maintain charge during storage.
Temperature Considerations
The built-in low-temperature cutoff protection prevents charging below 0°C (32°F) and allows discharge down to -20°C (-4°F). Charging automatically resumes when the temperature rises above 5°C (41°F).

Troubleshooting
The integrated BMS provides comprehensive protection. If the battery is not functioning as expected, check the following:
- No Power Output: Check if the BMS has triggered a protection mode (e.g., over-discharge, over-current, short circuit). Disconnect the load and allow the battery to rest or attempt to charge it with a compatible LiFePO4 charger to reset the BMS.
- Not Charging: Verify that the charger is specifically for LiFePO4 batteries and that the temperature is above 0°C (32°F). Ensure all connections are secure and correct polarity is maintained.
- Low Voltage: If the battery voltage is unusually low, the over-discharge protection may have activated. Attempt to charge the battery immediately.
- Overheating: The BMS includes overheating protection. If the battery feels excessively hot, disconnect it from the load/charger and allow it to cool down in a well-ventilated area.
