- 1x LiTime 12V 100Ah Group 24 All-around LiFePO4 Battery
4. Installation & Setup
4.1. Initial Activation
Upon first receipt or after switching off, the battery requires charging with a lithium-activation or MPPT charger to activate the Bluetooth function.
4.2. Physical Installation
The battery is a universal Group 24 fit, directly replacing old lead-acid batteries without modifications. Ensure proper terminal connections using the provided M8-16 terminal bolts. If screws are attached directly or if the thickness of the OT terminal sheet of the harness is less than 2mm, add shims for locking.

4.3. System Expansion
The battery supports connecting up to 16 units (4P4S configuration) for a massive 51.2V 400Ah system, providing up to 20.48kWh of energy storage. This is ideal for large RVs, home backup, and trolling motors.
5. Operating Instructions
5.1. Bluetooth Monitoring
Download the LiTime App to your smartphone. Once activated, connect via Bluetooth 5.0 to view real-time data including voltage, current, power, State of Charge (SOC), remaining capacity, temperature, and cycle times. The app also allows control over heating modes.
5.2. Low Temperature Operation
The battery features automatic low-temperature cut-off protection. Charging automatically turns off below 0°C (32°F) and resumes above 5°C (41°F). Discharging automatically turns off below -20°C (-4°F). The self-heating function ensures the battery is at an optimal temperature for charging in cold conditions.
