Description
REPT 345Ah LiFePO₄ Prismatic Battery Cell
The REPT 345Ah LiFePO₄ prismatic cell is a high-capacity lithium iron phosphate cell designed for large battery storage systems, off-grid homes, commercial battery banks, and long-duration energy storage projects.
Important: high capacity does not mean high power
These cells are best suited to substantial energy storage with relatively gentle charging and discharging. Check your power requirements before buying: their listed continuous charge and discharge limit is 0.25C, or 86.25 A per 345Ah cell. A more conservative 0.2C operating rate is 69 A. The same current flows through every cell in a series-connected battery.
Example: a 12 V battery powering a 2,000 W inverter
Four cells in series make a 12.8 V nominal, 345Ah battery. They increase the voltage, not the amp-hour capacity or permitted current. Although the battery stores approximately 4.42 kWh nominal, one four-cell battery is a poor choice for supplying a continuous 2,000 W inverter load.
- At the listed 0.25C limit: 12.8 V × 86.25 A = approximately 1,104 W on the battery side, before inverter losses. Available AC output is lower.
- To supply a 2,000 W AC load: assuming 90% inverter efficiency, 2,000 ÷ (12.8 × 0.90) = approximately 174 A, or 0.50C — roughly twice the listed continuous current limit.
This example assumes the inverter is delivering the full 2,000 W, not simply that it has a 2,000 W nameplate. Current rises as battery voltage falls; appliance starting surges can add further demand. These figures are an illustration, not a complete system rating.
A higher-current BMS cannot increase the cells’ current rating. Choose cells and a properly designed battery system that suit both your sustained loads and surge requirements. Check charging current too, including simultaneous charging sources. If you are unsure, tell us your inverter model and the equipment you want to run before ordering.
Ordering your cells
Sold in cartons of four cells. The quantity you choose is the number of cartons, not individual cells. Each carton is a separate 23 kg dangerous-goods package measuring 45 × 35 × 30 cm.
- 1 carton = 4 cells.
- 4 cartons = 16 cells — enough cells for one 51.2 V (16S) battery, with 17.66 kWh nominal capacity.
- 12 cartons = 48 cells — enough cells for three 16-cell batteries.
- 40 cartons = 160 cells — enough cells for ten 16-cell batteries.
BMS, enclosure and other battery-building components are not included. The optional carton calculator can fill the normal quantity field for you. Nominal capacity is not usable energy or a complete system design.
At 345Ah, each cell stores approximately 1,100Wh of energy. That is around 10% more capacity than a typical 314Ah cell, while remaining in a very similar physical size. For larger systems, that extra capacity adds up quickly.
For example, in a 16-cell 51.2 V battery, compare both stored energy and continuous power:
- EVE MB31 314Ah: approximately 16.08 kWh nominal energy and 8.04 kW at 0.5C (157 A).
- EVE LF334 334Ah: approximately 17.10 kWh nominal energy and 17.10 kW at 1C (334 A).
- EVE LF304 304Ah: approximately 15.56 kWh nominal energy and 15.56 kW at 1C (304 A).
- REPT 345Ah: approximately 17.66 kWh nominal energy and 4.42 kW at 0.25C (86.25 A).
More stored energy does not automatically mean more available power. In this comparison, the REPT cells provide more nominal storage than the MB31 cells, but lower continuous power.
Power figures are calculated from the stated cell C-rates at the nominal 51.2 V battery voltage and represent battery-side DC power before inverter losses, not a guaranteed complete-system output. Available AC output is lower, and power at the same current falls as battery voltage drops. The BMS, wiring, protection, inverter and operating conditions may impose lower limits; follow the applicable cell datasheet and system design.
That gives about 1.6kWh extra capacity per 16-cell battery pack.
These are A Grade / Automotive Grade quality cells, suitable for serious energy storage applications where long service life, stable performance, and high usable capacity are important.
Why Choose REPT 345Ah Cells?
The REPT 345Ah cell can be considered an upgrade from the previous 314Ah generation of LiFePO₄ cells. It is especially well suited to larger battery banks, where space efficiency and total usable capacity matter.
These cells are ideal for:
- Off-grid homes
- Large solar battery systems
- 50kWh to 150kWh battery banks
- Commercial energy storage
- Backup power systems
- Wind and solar storage projects
- Long-duration energy storage applications
The main advantage is simple: more storage capacity in almost the same space.
For customers building larger off-grid or hybrid battery systems, this extra capacity can reduce the number of cells or battery modules required for the same total storage capacity.

REPT has gained attention for producing high-capacity LiFePO₄ cells with strong performance and excellent energy density for large-format prismatic cells.
Summary
The REPT 345Ah LiFePO₄ cell is a strong option for customers who want more usable storage capacity from a high-quality large-format prismatic cell.
Compared with 314Ah cells, it provides around 10% more capacity, making it especially attractive for large battery systems where every extra kilowatt-hour matters.
It is best suited to larger, lower-C-rate systems such as off-grid homes, commercial storage, and large solar battery banks. When used correctly, with conservative charge and discharge rates, these cells are designed to provide long service life and excellent value per kWh.
