EU Stock Grade A+ EVE 3.2V 280Ah Rechargeable LiFePO4 Battery Cell Double Threads

Each terminal carries two threaded M6 studs stacked in one pole, instead of the single-stud standard design:

• Secure busbar clamping — two screws per connection mean the busbar cannot rotate or work loose under vibration
• Extra connection point — attach a busbar plus a BMS sense wire, temperature probe, or balancer lead on the same pole without stacking lugs
• Simpler compression builds — the screw head sits flush against the compression plate and cell face

Accessories included: the order comes with busbars, bolts and studs with double screw holes, plus the flexible busbar and epoxy sheet. Single-hole busbars will not seat properly on double-thread cells, so use the included hardware or order matching double-hole busbars.

HSEV is the top tier in Gobel Power's four-level consistency grading (ESS → LSEV → HSEV- → HSEV):

• Intact original QR code on every cell — decode it with our Cell QR Decoder tool on the website to see that cell's real measured capacity, voltage, IR, production date, and batch data
• Matched IR and matched voltage — cells in your order are sorted for uniform internal resistance and voltage, so your DIY battery pack starts balanced from the first cycle
• Production within 6 months — fresh stock, not warehouse-aged cells
• Capacity Testing Data Sample and Official Standards documents available for download on the product page
• Manufacturer's data sheet verified by Gobel Power technicians — we guarantee the product is authentic

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 LF280K cells carry the intact original EVE QR code and verify on EVE's traceability system.

The LF280K V3 is rated for 8,000 charge/discharge cycles at 25°C to 70% SOH — over 21 years of daily cycling, with only 2–4% capacity fade per year under normal use — backed by a 5-year warranty.

Build ideas:

• 16S DIY battery pack — ~14.3kWh at 51.2V for home solar energy storage
• Server rack battery — pairs with our 51.2V 16S DIY kit case with JK BMS (WiFi version available)
• 12V / 24V / 48V off-grid systems and EV conversions
• Campervan and marine house power (household loads only — not for propulsion)

For 16S packs, set the inverter/charger to 55.2V max charge voltage, up to 150A charge / 200A discharge, in lithium (CAN/RS485) or lead-acid mode, keep the SOC window within 10%–90%, and fully charge to 100% at least once a month to keep BMS SOC readings accurate.

Important: do not mix LF280K with 314Ah, 306Ah, or other capacities (or different production versions) in the same pack — mixing different types of LiFePO4 cells causes imbalance and shortens pack life.
