EU Stock EV Grade A+ EVE 3.2V 306Ah MB30 Rechargeable LiFePO4 Battery Cell

They are actually the same cell platform — EVE just tuned the claims differently:

• EVE 306Ah (MB30): claimed lower capacity but longer cycle life — 10,000 cycles
• EVE 314Ah (MB31): claimed higher capacity but shorter cycle life — 8,000 cycles
• Identical footprint: 207.5 × 72 × 173.7mm — the same 72mm prismatic format, so they share the same compression fixtures, busbar kits, and rack enclosures
• Status: the 306Ah MB30 has been discontinued by EVE; the 314Ah MB31 is the current production model

Important: do not mix MB30 and MB31 cells (or cells of different capacities or production versions) in the same 16S battery pack — mixing different types of LiFePO4 cells reduces pack life and can create imbalance and safety risks.

If you want the 10,000-cycle endurance class in the standard 72mm format, the remaining EU-stock MB30 is the pick; for future expandability with matching in-production cells, the 314Ah is the safer long-term choice.

Yes — this listing ships from our European warehouse (EU delivery only), with local delivery in 7–15 days — no 1–2 month ocean freight wait from China.

Shipping zones (surcharge shown at checkout):

Tax and customs: the price is tax-free to your door — all import duties have already been paid, so there is no customs clearance on LiFePO4 battery cells within the EU. Note that because we ship via our EU freight forwarder, no VAT invoice can be issued for EU warehouse orders.

Also included: a 30-day free return to the local warehouse.

HSEV is the top tier in Gobel Power's four-level consistency grading (ESS → LSEV → HSEV- → HSEV) — the same tier EVE sells in its official shop:

• ★★★★ capacity consistency — cells matched for uniform capacity, voltage, and internal resistance
• Intact original QR code on every cell — scan or enter the code into our Cell QR Decoder tool on the website to see that cell's real measured capacity, voltage, IR, production date, and batch data
• Official EVE test report and sample-cell batch data published (latest batch 25/Mar/2024, production Feb/2024)
• Tested before shipping, backed by real data

Market "Grade A" labels vary wildly — some sellers relabel Grade B cells or ship cells with fake QR codes and no test reports. EVE now prints a B Mark on all ESS-grade cells so ESS stock can't be passed off as HSEV; these cells carry no B Mark and verify as genuine EVE LiFePO4 cells on EVE's traceability system.

The MB30 is rated for 10,000 charge/discharge cycles — nearly 27 years of daily cycling at one cycle per day — with only 2–4% capacity fade per year under normal use, backed by a 5-year warranty. Cobalt-free LiFePO4 chemistry is inherently stable with no thermal runaway risk, and the 0.5C/0.5C continuous rating plus the 10%–90% SOC window preserves full cycle life in daily solar service.

Build ideas:

• 16S DIY battery pack — ~15.7kWh at 51.2V for home solar energy storage
• Server rack battery — pairs with our 16S LiFePO4 DIY kit case with JK BMS (WiFi version available)
• 12V / 24V / 48V off-grid systems — discharges down to -30°C for cold-climate installations
• Campervan and marine house batteries — EU-local stock simplifies transport compliance (not for propulsion)

Busbars, bolts, flexible busbar, and epoxy sheet are all included, so your pack assembly starts the day the cells arrive. Charge with an inverter or charger set to 55.2V max charge voltage (16S), up to 150A charge / 200A discharge, in lithium (CAN/RS485) or lead-acid mode.
