INNPO 3.2V 314Ah Grade A Prismatic LiFePO4 Cell

INNPO 3.2V 314Ah Grade A Prismatic LiFePO4 Cell

The INNPO 3.2V 314Ah Grade A Prismatic LiFePO4 Cell is a high-capacity lithium iron phosphate cell for engineered battery packs. At 3.2V and 314Ah, it stores approximately 1.0048kWh 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.

Verified product information

Residential ESS and large custom battery banks

Each cell stores about 1.0048kWh nominal. Four matched cells form roughly 4.02kWh at 12.8V, eight form about 8.04kWh at 25.6V and sixteen form about 16.08kWh at 51.2V. These calculations are nominal; usable system energy depends on operating limits, 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.
