One cell.
One kilowatt-hour.
The Cornex 3.2V 314Ah prismatic LiFePO4 battery cell — an HSEV- grade building block for DIY battery packs, solar storage, and energy systems built to last.
Fewer cells.
Simpler builds.
At 314Ah and 3.2V, one Cornex cell stores about 1.0kWh. Stack sixteen and you have a 5kWh pack with fewer cells, fewer connections, and fewer points of failure.
- 314Ah typical capacity, 3.2V nominal voltage
- Roughly 1.0kWh of energy per cell
- 1C/1C continuous charge and discharge
- 2C/2C pulse for 60 seconds
Rated for years.
Not just months.
LiFePO4 chemistry ages slowly and predictably. This cell is verified for 8,000 cycles, so a pack you build today keeps working well past the point most batteries get retired.
- 8,000 charge / discharge cycles
- Stable, inherently safe LiFePO4 chemistry
- Recommended 10%–90% SOC window
- Low self-discharge in storage
Matched, so every
cell pulls its weight.
A pack is only as good as its weakest cell. Every HSEV- cell ships with matched internal resistance, voltage, and capacity — so your build stays balanced from the very first cycle.
- HSEV- grade with matched IR
- Matched voltage and matched capacity
- AC impedance ≤ 0.17mΩ
- Flexible busbars and epoxy sheet included
From 12V to
grid-scale.
A standard prismatic format that drops into 12V, 24V and 48V builds. It charges down to 0°C and discharges to −30°C, so it works where you do.
- 207.2 × 71.7 × 173.7 mm, 5.65 kg
- Charge 0°C–55°C, discharge −30°C–55°C
- M6 threaded terminals — single-pole or double-thread
- MSDS, UN38.3 and CE certified
Built for every
way you use it.
From a small off-grid setup to a full home energy storage system, the Cornex 314Ah cell is the foundation.
Build the pack
you've been planning.
Verified capacity, matched consistency, and an 8,000-cycle life — the Cornex 314Ah HSEV- cell is the foundation for a pack you won't have to think about again.
