The EVE MB31 314Ah LiFePO4 battery cell
that builders trust.
A genuine HSEV Grade A+ EVE MB31 3.2V 314Ah LiFePO4 prismatic cell — production within 6 months, QR traceable to EVE's factory line, batch matched, and shipping today from our European warehouse. The premium LiFePO4 battery cell for solar energy storage and DIY battery builds that demand the freshest stock.
See every detail of your LiFePO4 cell.
High-resolution photos of the actual EVE MB31 314Ah LiFePO4 battery cell — QR code, terminal, and side profile.
Not all Grade A LiFePO4 cells
are created equal.
GobelPower's HSEV standard means every EVE MB31 314Ah LiFePO4 battery cell is factory-direct from EVE, produced within the last 6 months, with an intact scratch-to-reveal QR code that verifies on EVE's official traceability system. We include a per-batch test report with every order — capacity, voltage, internal resistance, and visual inspection data — so you know exactly what's in your LiFePO4 battery build, before you build it.
- Intact scratch-to-reveal QR code on every EVE MB31 LiFePO4 cell — scan on EVE's official system to verify authenticity, production date, and factory line
- Factory-direct HSEV Grade A+ sourcing — no middlemen, no relabeling, no warehouse-aged LiFePO4 stock
- Production within 6 months — not last year's leftovers sold as "new" Grade A prismatic cells
- EV-grade LiFePO4 chemistry — built for electric vehicles, exceeds stationary solar energy storage requirements
- Visual inspection on every 314Ah cell — no swollen casing, no dented corners, no terminal corrosion
Cycle it daily.
Retire it decades later.
EVE rates the MB31 LiFePO4 battery cell at 8,000 cycles to 70% state of health at 25°C — that's over 21 years of daily cycling. In real-world testing, these 314Ah cells routinely deliver 330Ah+ of actual capacity. With ≤0.18mΩ internal resistance, this LiFePO4 prismatic cell runs cooler and more efficiently than the previous generation. In a typical solar energy storage system cycling once per day, these cells will outlast the inverter, the rack, and likely the house they're mounted in.
- 8,000+ cycle life at 0.5C, 25°C — to 70% SOH (with compression fixture)
- 314Ah nominal capacity on this LiFePO4 battery cell — routinely tests 330Ah+ in real-world conditions
- ≤0.18mΩ internal resistance (AC, 1kHz) — low-IR LiFePO4 cell runs cooler, more efficient under load
- Standard charge/discharge at 0.5C — conservative, cell-friendly operating window
- Wide temperature range: charge 0~60°C, discharge -30~60°C
- Cobalt-free LiFePO4 chemistry — inherently stable, no thermal runaway, no cobalt supply chain
Every Grade A prismatic cell in a batch,
matched to within 1%.
A LiFePO4 battery is only as strong as its weakest cell. Before any EVE MB31 cell leaves our warehouse, we sort and match every batch by capacity, voltage, and internal resistance. When you order 4, 8, or 16 LiFePO4 battery cells together, they arrive ready to build — no balancing headaches, no weak links in your solar energy storage pack.
- Capacity matching: ≤1% variance within each shipped batch of LiFePO4 prismatic cells
- Voltage matching: ≤5mV difference across all EVE MB31 cells in your order
- Internal resistance matching: ≤0.02mΩ variance
- Self-discharge screening — LiFePO4 cells held and re-tested before packing
- Each batch ships with a detailed matching report — not just a promise
EU warehouse LiFePO4 battery cells —
shipped so they arrive like they left.
A dented LiFePO4 cell is a dead cell. Every EVE MB31 order leaves our EU warehouse in custom-cut dense foam with individual cell separators, double-walled cartons, and moisture protection — whether you order 4 cells or 400. And because these LiFePO4 battery cells ship from inside Europe, there's no customs clearance, no import duties, and delivery in days, not months.
- Custom-cut high-density EVA foam — each 314Ah LiFePO4 cell sits in its own cavity
- Individual cell separators prevent terminal-to-terminal contact during transit
- Double-walled export-grade cartons with reinforced edges
- Silica gel desiccant packs in every box — moisture control for LiFePO4 cells during transit
- EU warehouse dispatch — delivery typically 7–15 business days within Europe, no customs
- Full insurance coverage on every LiFePO4 battery cell shipment
LiFePO4 battery cells for every build.
From a DIY 12V camper battery to a 48V solar energy storage wall — the EVE MB31 314Ah LiFePO4 prismatic cell is the cell builders reach for when reliability is non-negotiable.
