The EVE MB31 314Ah LiFePO4 battery cell.
Same performance. Smarter price.
A genuine EVE MB31 3.2V 314Ah LiFePO4 rechargeable battery cell — the same 8,000-cycle endurance and factory-line authenticity builders trust, from an earlier production run at a factory-direct price. QR traceable, batch matched, and ready for your next solar energy storage or DIY battery build.
A Grade A LiFePO4 prismatic cell
that proves where it came from.
Every EVE MB31 314Ah LiFePO4 battery cell in this batch comes from EVE Energy's production line with an intact scratch-to-reveal QR code — scan it on EVE's official traceability system and you'll see the authentic production date and factory line. These were previously sold as HSEV Grade A stock; we grade them A− solely because of the production date. The LiFePO4 prismatic cell inside is identical in construction and chemistry to current-production units.
- Intact scratch-to-reveal QR code on every EVE MB31 LiFePO4 cell — verifies on EVE's official traceability platform
- Production date: June 2023 – February 2024 — clearly disclosed for every Grade A prismatic cell
- EV-grade LiFePO4 chemistry — the same cobalt-free cathode used in electric vehicle battery cells
- Visual inspection on every 314Ah cell — no swollen casing, no dented corners, no terminal corrosion
- Factory-direct from Shenzhen — no middlemen, no relabeling, no warehouse-aged LiFePO4 stock
An 8,000 cycle life LiFePO4 battery
that outlasts the build.
Nothing changed under the hood. This EVE MB31 3.2V LiFePO4 rechargeable battery cell carries the same 314Ah nominal capacity — routinely testing 330Ah+ in real-world conditions — with the same ≤0.18mΩ internal resistance and the same 8,000-cycle rating at 0.5C, 25°C. The production date is earlier; the cycle life and capacity are not. In a solar energy storage system cycling once a day, this LiFePO4 battery cell will outlast most of the equipment around it.
- 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 discharge
- ≤0.18mΩ AC internal resistance (1kHz) — low-IR LiFePO4 cell runs cooler under load
- Standard 0.5C charge/discharge current — a conservative, cell-friendly operating window
- Wide temperature tolerance: charge 0~60°C, discharge −30~60°C
- Cobalt-free LiFePO4 chemistry — inherently stable, no thermal runaway risk
Factory direct LiFePO4 cells —
tested, matched, packed to perform.
You're buying factory-direct LiFePO4 battery cells from our Shenzhen warehouse — no distributor markup, no middleman relabeling. Before shipping, every EVE MB31 cell is batch matched by capacity (≤1%), voltage (≤5mV), and internal resistance (≤0.02mΩ). Then each Grade A LiFePO4 prismatic cell goes into custom-cut EVA foam inside double-walled export cartons. A detailed test report ships with every order. If you're building a solar energy storage pack or a DIY battery bank and want the lowest cost-per-cycle on genuine EVE cells, this is it.
- Production date range: June 2023 – February 2024 — clearly disclosed, transparent grading on every LiFePO4 cell
- Batch matched LiFePO4 prismatic cells — capacity ≤1%, voltage ≤5mV, IR ≤0.02mΩ variance
- Custom-cut high-density EVA foam — each 3.2V 314Ah cell sits in its own protective cavity
- Double-walled export-grade cartons with reinforced edges and silica gel desiccant packs
- 4-year warranty on every EVE MB31 LiFePO4 battery cell — genuine coverage, genuine cells
- Detailed batch report included — capacity, voltage, IR, and visual inspection data per order
LiFePO4 battery cells for every build.
From a 12V DIY battery build to a 48V solar energy storage system — the EVE MB31 314Ah LiFePO4 prismatic cell is the foundation builders choose when every amp-hour counts and every dollar matters.
Genuine EVE MB31 314Ah LiFePO4 cells.
Factory direct. Smarter price.
Genuine EVE MB31 3.2V 314Ah Grade A LiFePO4 prismatic battery cells with intact QR codes, batch matched to within 1%, backed by a 4-year warranty — factory-direct from Shenzhen at a price that leaves room in your budget for the rest of your solar energy storage or DIY battery build. Same 8,000-cycle LiFePO4 battery cell. Smarter price. That's the whole story.
