Lithium Iron Phosphate Battery ULTRACELL LFP12.8-30 — 12.8V 30Ah with T12 (M2) terminal and Bluetooth

The ULTRACELL Lithium Iron Phosphate Battery LFP12.8-30 is a sealed rechargeable energy storage unit that provides a nominal voltage of 12.8V and a usable capacity of 30Ah. The compact pack incorporates an integrated battery management system (BMS) that protects against overcharge, over-discharge and short circuit, while the T12 (M2) terminal ensures secure mechanical and electrical connection. Bluetooth monitoring enables real-time state-of-charge and health data on compatible devices, making the battery suitable for repeated cycling and dependable standalone power applications.

Advantages

This LiFePO4 battery delivers long cycle life, stable discharge voltage and a higher usable capacity compared with equivalent lead-acid types of similar size. The built-in protection circuitry reduces the need for external safety components and helps prevent deep discharge and overcurrent events. Bluetooth monitoring provides convenient remote access to voltage, current, temperature and state-of-charge information, allowing straightforward system integration and monitoring. The sealed construction and compact dimensions simplify installation in confined spaces.

Suitable for

• Off-grid solar energy storage for small to medium systems
• Uninterruptible power supply (UPS) for electronics and network devices
• Telecommunications backup and repeater sites

How to use

Install the battery on a level, stable surface with adequate ventilation and secure the T12 (M2) terminal connections using appropriate torque and corrosion-resistant hardware. Connect to a compatible charger or system that supports LiFePO4 charging profiles: typical recommended charge voltage and current specifications should be followed according to the system documentation. Use the Bluetooth interface or a compatible monitoring app to verify initial state-of-charge and to monitor voltage, current and temperature during operation. Avoid exposing the battery to extreme temperatures and do not bypass the integrated protection circuitry.

Usage recommendations

For best long-term performance, charge the battery regularly and avoid prolonged storage at a fully discharged state. Use a charger or charge controller configured for LiFePO4 chemistry, limit continuous discharge current within the battery’s rated capability, and monitor temperature during heavy use. When integrating into photovoltaic, UPS or telecom systems, ensure compatible charging parameters and proper fusing on the DC lines to protect against short circuits and excessive currents.
