4.3. Extended Cycle Life & BMS
The Redodo 12.8V 100Ah LiFePO4 battery offers an impressive cycle life of 4000 to 15000 cycles, providing up to 8 times the lifespan of a typical SLA battery. It features a built-in 100A Battery Management System (BMS) with Grade A cells, offering five key protections:
- Over-Charge Protection
- Over-Discharge Protection
- Over-Current Protection
- Short-Circuit Protection
- High-Temperature Protection

4.4. Expandability
The battery supports both series and parallel connections, allowing for flexible system expansion. You can connect up to 4 batteries in series for a 51.2V 100Ah system, or up to 4 batteries in parallel for a 12.8V 400Ah system. For larger energy needs, a 4P4S configuration (16 batteries) can achieve a 51.2V 400Ah system with 20.48KWh of energy.
5. Applications
This versatile battery is ideal for various deep cycle applications:
- RVs, Vans, Campers: Provides reliable power for onboard electronics and appliances.
- Solar Power Storage: Efficiently stores energy from solar panels for off-grid living or backup power.
- Trolling Motors: Suitable for trolling motors with 30-70lbs thrust.

6. Setup & Installation
Before connecting the battery, ensure all terminals are clean and free of corrosion. Use the provided M8 screws to secure cable lugs to the battery terminals. Tighten connections firmly to prevent resistance and heat buildup.
For optimal performance and safety, it is recommended to fully charge each battery individually before connecting them in series or parallel. This ensures all batteries are at a balanced state of charge.
7. Charging Instructions
The Redodo 12.8V 100Ah LiFePO4 battery should be charged using a 14.6V 20A (0.2C) LiFePO4 battery charger. This typically takes around 5 hours for a full charge. The battery can be fully charged in as little as 1 hour with a 100A charging current.
7.1. Recommended Charging Methods:
- Dedicated LiFePO4 Charger (14.6V 20A)
- Solar Panel with MPPT Charge Controller
- Generator with AC-DC Converter
- Alternator with DC-DC Charger

8. Series & Parallel Connection
To connect batteries in series or parallel, ensure they are of the same brand, capacity (Ah), and BMS (A). It is crucial that all batteries are at the same state of charge before connecting them. Use appropriate gauge copper cables for connections.
8.1. Series Connection:
Connect the positive terminal of one battery to the negative terminal of the next. This increases the total voltage of the battery system.
8.2. Parallel Connection:
Connect positive terminals to positive terminals and negative terminals to negative terminals. This increases the total amperage (Ah) of the battery system.
9. Maintenance
The Redodo LiFePO4 battery is designed for minimal maintenance. However, following these guidelines will help maximize its lifespan:
- Regular Inspection: Periodically check terminal connections for tightness and signs of corrosion.
- Cleaning: Keep the battery clean and dry. Use a damp cloth to wipe the exterior.
- Long-Term Storage: If storing the battery for an extended period (more than 3 months), charge it to 50% capacity and store in a cool, dry place (recommended temperature: -10°C to 35°C / 14°F to 95°F). Recharge every 3 months to maintain optimal health.
10. Troubleshooting
If you encounter issues with your battery, refer to the following general troubleshooting steps:
- No Power Output: Check all cable connections for tightness. Verify the battery voltage is above the minimum discharge voltage. If the battery is in protection mode, disconnect all loads and chargers for 30 minutes to allow the BMS to reset.
- Charging Issues: Ensure your charger is compatible with LiFePO4 batteries and provides the correct voltage (14.6V) and current. Check for any fault indicators on the charger or MPPT controller.
- Low Temperature Cut-off: The BMS will automatically stop charging if the battery temperature drops below 0°C (32°F) to prevent damage. Charging will resume once the temperature rises.
