3. Product Overview
The HumsiENK 12V 100Ah LiFePO4 Battery is a high-performance, durable power solution designed for various applications, including RVs, solar energy systems, off-grid setups, and trolling motors. It offers significant advantages over traditional lead-acid batteries.
3.1 Key Features
- Durable and Long-lasting: Offers 5000 cycles at 100% Depth of Discharge (DOD) and a lifespan of up to 10 years, which is six times longer than traditional lead-acid batteries.
- High Quality Cells: Constructed with A+ grade battery cells, certified with SDS/UN38.3/FCC/CE/ROHS for high standards of quality and safety.
- Compact and Lightweight: With dimensions of 8.2 x 6.6 x 10.2 inches and a weight of 23.2 lbs (10.5 kg), it meets BCI Group 24-31 standards, reducing space and weight by over 30% compared to equivalent lead-acid batteries.
- Integrated BMS: Features an intelligent 100A Battery Management System (BMS) that protects against various conditions including low temperature, over-discharge, over-charge, high temperature, short circuit, and over-current (automatically disconnects if discharge current exceeds 300±50A).
- IP67 Waterproof Rating: Designed to be impact-resistant and IP67 waterproof, making it suitable for marine and outdoor environments.
- Low Temperature Protection: Operates smoothly in temperatures from -4°F (-20°C) to 158°F (70°C) and automatically shuts down below -4°F (-20°C) to prevent damage.

4. Setup and Installation
The HumsiENK 12V 100Ah LiFePO4 battery is designed for flexible system configurations.
4.1 System Expansion
This battery supports expansion up to 48V and 20kWh. You can connect up to four batteries in series, four batteries in parallel, or a combination of both to create your desired power station. Always ensure all batteries are of the same voltage and capacity when connecting in series or parallel.
- Series Connection: Increases total voltage (e.g., 4 x 12V batteries in series = 48V).
- Parallel Connection: Increases total capacity (e.g., 4 x 100Ah batteries in parallel = 400Ah at 12V).

4.2 Applications
The lightweight and compact design, along with its robust performance, makes this battery ideal for:
- Recreational Vehicles (RVs)
- Outdoor Activities
- Boats (fish finders, yachts, trolling motors)
- Off-Grid Systems
- Home Backup Power Sources
- Garden Equipment (lawn mowers, trimmers)
- Portable Electronic Devices (LED lights, phones, fans, laptops)

6. Maintenance
Proper maintenance ensures the longevity and performance of your LiFePO4 battery.
- Regularly inspect battery terminals for corrosion and ensure connections are secure.
- Keep the battery clean and dry.
- Store the battery in a cool, dry place when not in use for extended periods.
- Avoid fully discharging the battery for prolonged periods.
- If storing for a long time, charge the battery to approximately 50% state of charge.
7. Troubleshooting
The built-in BMS is designed to prevent most common issues. If the battery appears unresponsive or is not performing as expected, consider the following:
- No Power Output: Check if the battery has entered a protection state (e.g., over-discharge, over-current, low temperature). The BMS will automatically disconnect. Reconnect to a charger to reset the BMS if it's an over-discharge protection.
- Not Charging: Ensure the charger is compatible with LiFePO4 batteries and is functioning correctly. Check if the ambient temperature is above 32°F (0°C) as the BMS will prevent charging below this temperature.
- Reduced Performance: Verify all connections are tight and free of corrosion. Ensure the load is within the battery's specified limits.
- Over-Current/Short Circuit: The BMS will automatically disconnect the battery. Remove the load or clear the short circuit, then reconnect to reset.
If issues persist, contact HumsiENK customer support.
