Introduction
This manual provides essential information for the safe and efficient operation, installation, and maintenance of your SOK Battery 206Ah 12V LiFePO4 Lithium Iron Phosphate Deep Cycle Battery. Designed for reliability and longevity, this battery is ideal for various applications including RVs, marine vessels, and off-grid solar systems. Please read this manual thoroughly before using the product.
Product Features
- Advanced LiFePO4 Technology: Offers 4000-8000 cycles, significantly outperforming lead-acid batteries (10x longer cycle life) while being less than 40% of their weight. Features no memory effect, ensuring consistent capacity retention.
- Integrated Intelligent BMS: Built-in Battery Management System provides comprehensive protection including low temperature charging cut-off, high temperature charging/discharging cut-off, overcharge/discharge protection, overcurrent protection, and short circuit protection. It also features automatic cell balancing for enhanced battery life.
- Bluetooth APP Monitoring: Allows real-time monitoring of battery data (voltage, charge/discharge voltage, current) via a mobile application (ABC-BMS APP). This feature aids in long-term battery health management. Connection distance is up to 10 meters.
- Low Temperature Charging Capability: Designed to charge in temperatures as low as -4°F (-20°C). When ambient temperature is below 32°F (0°C), the charging current (>10A) activates an internal heating film. Once the internal battery temperature reaches 41°F (5°C), the heating function deactivates, and charging commences. The heating function activates only when charging begins.
- Versatile Application: Suitable for a wide range of uses including solar home systems, RVs, campers, solar/wind energy storage, marine applications (ships, boats, trolling motors), and travel trailers.

Setup
1. Initial Inspection and Charging
Upon receiving your SOK battery, inspect it for any physical damage. While batteries are often partially charged upon delivery, it is recommended to fully charge them before first use to ensure cell balancing and optimal performance. Use a compatible LiFePO4 charger.
2. Connecting Batteries in Series
If connecting multiple batteries in series for higher voltage applications, ensure all batteries are at the same state-of-charge (SOC) before making connections. This is crucial for balanced operation and longevity of the battery bank.

3. Bluetooth APP Setup (ABC-BMS)
- Download the "ABC-BMS" application from your mobile device's app store.
- Ensure your battery is powered on and within 10 meters of your mobile device.
- Open the ABC-BMS app and connect to your SOK battery via Bluetooth.
- Once connected, you can monitor various battery parameters in real-time.
Operating Instructions
General Operation
The SOK LiFePO4 battery is designed for deep cycle applications. It can be discharged significantly without damage, unlike lead-acid batteries. The built-in BMS manages charging and discharging parameters to protect the battery cells.
Low Temperature Charging
The battery features an internal heating system for cold weather charging. If the ambient temperature is below 32°F (0°C) and a charging current greater than 10A is applied, the internal heater will activate. Charging of the cells will only begin once the internal temperature reaches 41°F (5°C). This ensures safe charging in cold conditions.

Maintenance
SOK LiFePO4 batteries require minimal maintenance compared to lead-acid batteries. However, regular checks can prolong their lifespan.
- Terminal Inspection: Periodically check battery terminals for corrosion or loose connections. Clean and tighten as necessary.
- Physical Inspection: Ensure the battery casing is free from damage. The ABS shell provides robust protection.
- BMS Monitoring: Utilize the Bluetooth APP to regularly monitor battery health, cell voltage balance, and overall performance.
- Storage: If storing the battery for extended periods, ensure it is charged to approximately 50% State of Charge (SOC) and stored in a cool, dry place.
- Repairability: SOK batteries are designed with repairability in mind. Components such as individual cells and the BMS board can be replaced if necessary, extending the overall service life of the battery.
Troubleshooting
Battery Enters Sleep Mode
The battery may enter a "sleep mode" after several hours of no charge or discharge activity to conserve power. If the battery appears unresponsive:
- Solution: Wake the battery up by applying a charging current. Connect a compatible charger, and the battery should exit sleep mode and resume normal operation.
Bluetooth Connectivity Issues
- Check Distance: Ensure your mobile device is within 10 meters of the battery.
- App Restart: Close and reopen the ABC-BMS app.
- Battery Power: Confirm the battery is powered on.
Battery Not Charging in Cold Temperatures
- Check Current: Ensure the charging current is greater than 10A to activate the internal heater.
- Wait for Heating: The battery will not charge until its internal temperature reaches 41°F (5°C). Allow time for the heating function to warm the cells.
