The cell that
builders trust.
A genuine HSEV Grade A+ EVE 3.2V 314Ah LiFePO4 prismatic cell — production within 6 months, QR traceable to EVE's factory line, batch matched, and shipping factory-direct from our Shenzhen warehouse.
Not all Grade A cells
are created equal.
GobelPower's HSEV standard means every MB31 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 build, before you build it.
- Intact scratch-to-reveal QR code on every cell — scan on EVE's official system to verify authenticity, production date, and factory line
- Factory-direct HSEV sourcing — no middlemen, no relabeling, no warehouse-aged stock
- Production within 6 months — not last year's leftovers sold as "new"
- EV-grade certification — built for electric vehicles, exceeds stationary storage requirements
- Visual inspection on every cell — no swollen casing, no dented corners, no terminal corrosion
Cycle it daily.
Retire it decades later.
EVE rates the MB31 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 cells routinely deliver 330Ah+ of actual capacity. With ≤0.18mΩ internal resistance, they run cooler and more efficiently than the previous generation. In a typical home storage setup cycling once per day, these cells will outlast the inverter, the rack, and likely the house they're mounted in.
- 8,000+ cycles at 0.5C, 25°C — to 70% SOH (with compression fixture)
- 314Ah nominal capacity — routinely tests 330Ah+ in real-world conditions
- ≤0.18mΩ internal resistance (AC, 1kHz) — less heat, higher efficiency 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 cell tested.
Every order battle-packed.
A battery is only as strong as its weakest cell — and a dented cell is a dead cell. Before shipping, we sort and match every batch by capacity, voltage, and internal resistance. Then each cell goes into custom-cut high-density EVA foam with individual separators inside double-walled export cartons — whether you order 4 cells or 400. Your batch arrives tested, matched, and ready to build, with a detailed report included.
- Capacity matching ≤1%, voltage ≤5mV, IR ≤0.02mΩ variance within each shipped batch
- Custom-cut high-density EVA foam — each cell sits in its own cavity, terminals protected
- Double-walled export-grade cartons with reinforced edges and silica gel desiccant packs
- Self-discharge screening — cells held and re-tested before final packing
- Full insurance coverage on every shipment worldwide
- Detailed batch matching report included with every order — not just a promise, but proof
What will you build?
From a DIY 12V camper battery to a 48V home storage wall — the MB31 is the cell builders reach for when reliability is non-negotiable.
Build with the best.
Genuine EVE MB31 cells, HSEV Grade A+ verified, QR traceable to EVE's production line, batch matched, and backed by a 5-year warranty — factory-direct from Shenzhen, ready to ship worldwide. Whether you need 4 cells for a DIY build or a pallet for production, they arrive tested, matched, and packed to perform.
