INNPO 3.2V 280Ah Prismatic LiFePO4 Cell

INNPO 3.2V 280Ah Prismatic LiFePO4 Cell

The INNPO 3.2V 280Ah Prismatic LiFePO4 Cell is a high-capacity lithium iron phosphate cell for engineered battery packs. At 3.2V and 280Ah, it stores approximately 896Wh of nominal energy per cell. Its prismatic format is suitable for solar storage, off-grid systems, backup power and custom mobile-energy projects where the battery enclosure and protection system are designed around the cell.

High-capacity solar and off-grid projects

With 896Wh per cell, this format is aimed at high-capacity banks where fewer parallel strings can simplify the mechanical layout. A 16-cell 51.2V pack stores approximately 14.3kWh nominal, before allowing for system reserve and conversion losses.

Building a battery bank

Four matched cells in series form a nominal 12.8V pack; eight form 25.6V and sixteen form 51.2V. Series connection increases voltage while parallel connection increases capacity. Cells used together should be matched, balanced and installed with suitable busbars, compression or retention where specified, an insulated enclosure and correctly rated fuses.

BMS and charger selection

This is an individual cell, not a ready-to-use battery. It does not replace a complete battery with its own enclosure and protection. A correctly sized LiFePO4 BMS is required to monitor cell voltage and temperature and to control charging and loads. Select the BMS, charger, inverter and cabling for the complete pack voltage and the real continuous and peak current of the installation.

Before installation

• Measure and record the voltage of every cell before assembly.
• Use cells of the same capacity, type and state of charge in one pack.
• Do not exceed the limits in the current product datasheet.
• Provide overcurrent protection and prevent accidental short circuits.
• Do not charge outside the temperature range permitted for the cell.
