The 51.2V 280Ah LiFePO4 battery — 14.34kWh from a 16S1P pack — is the classic, battle-tested configuration that defined the home storage rack market. Built on the EVE LF280K cell, it remains in active production and wholesale supply worldwide. This page covers the specification, when to choose it over the newer 314Ah generation, and wholesale/OEM sourcing.

- Private label: logo, case colour, rating labels, manuals and carton print for your brand.
- Quality control: pre-shipment inspection items (visual, voltage/IR consistency, BMS function, labelling) agreed per order; third-party inspection can be arranged at the buyer's request.
- Export documents: UN38.3 test summary, SDS/MSDS and dangerous-goods (UN3480, Class 9) shipping paperwork for the exact model shipped, coordinated per order.
Commercial terms and certificates
- MOQ, price, lead time and warranty: confirmed per order in the quotation. No public list price.
- How orders usually run: sample or trial order → pilot order with your labels and documents → repeat orders on a locked specification.
- Market certificates (which ones depends on the destination market and application): available/arranged per project; certification and testing fees are borne by the buyer. We tell you which source holds each report before you order.
Before the first order, read the wholesale & distributor program, the MOQ & sample order guide and our supplier verification checklist. Related: 51.2V 314Ah model page, LiFePO4 cells wholesale.

Distributor FAQ
Can I buy 51.2V 280Ah LiFePO4 batteries wholesale?
Yes. Distributors, importers and installers can order the 51.2V 280Ah (14.34kWh) wholesale or as private label, in wall-mount, floor-standing or 19-inch rack enclosures, with CAN/RS485 set to your inverter. MOQ, price, lead time and warranty are confirmed per order.
What sets the wholesale price of a 51.2V 280Ah battery?
Cell brand and grade (280Ah-class cells), BMS and communication, enclosure type, heating, labelling and packaging, quantity and Incoterm. We do not publish a list price; you get a per-order quotation with the datasheet for the exact build.
Which documents come with a 51.2V 280Ah wholesale shipment?
For transport: UN38.3 test summary, SDS/MSDS and dangerous-goods (UN3480, Class 9) paperwork for the exact model, coordinated per order. Market certificates (e.g. IEC 62619, UL 1973, CE) are available/arranged per project; certification and testing fees are borne by the buyer.
280Ah vs 314Ah: Which to Choose?
| 280Ah (this page) | 314Ah (new generation) | |
|---|---|---|
| Nominal energy | 14.34kWh | 16.08kWh |
| Cell platform | EVE LF280K and equivalents — longest track record | EVE MB31 / CATL / REPT / CALB / Hithium / Gotion |
| Supply maturity | Most mature cell supply chain in the industry | Current ESS standard, growing supply |
| Best for | Cost-sensitive projects, proven-cell requirements, DIY | Maximum energy per pack, new installations |
The 280Ah generation is not obsolete — it is the most field-proven 16S configuration in existence. Choose 280Ah when proven supply and cost matter most; choose 51.2V 314Ah (16.1kWh) when maximum energy density per pack is the priority.
Cell Options
The EVE LF280K is one of the most produced LiFePO4 cells in history, with equivalents from CATL, REPT, CALB, and Hithium. LJY Energy verifies cell model, grade, and batch documentation per project; UN38.3 test summaries and MSDS are supplied. Specifications, pricing, MOQ, and lead times are confirmed per project. For cell-level sourcing, see LiFePO4 battery cells wholesale.
Applications
- Residential solar storage: 14.3kWh covers typical household overnight loads with 5–8kW hybrid inverters.
- Server rooms and UPS: 19″ rack form factor for equipment backup.
- DIY and installer builds: the best-documented 16S configuration in the DIY community.
- Light commercial backup: paralleled racks for workshops and small businesses.
BMS and Customization Options
- Communication BMS: CAN/RS485 with selectable low-voltage inverter protocols (e.g. Pylontech-compatible CAN); pairing confirmed per inverter model and firmware — see our BMS selection guide.
- Bluetooth BMS: mobile monitoring options.
- Parallel expansion: supported; the maximum parallel count depends on the BMS / inverter pairing and is confirmed per project.
- OEM branding: private-label enclosures and specification sheets.
Wholesale and OEM/ODM
51.2V 280Ah remains an active wholesale SKU. LJY Energy supplies this classic configuration wholesale and supports OEM/ODM programs. For new maximum-density projects, also consider the 51.2V 314Ah (16.1kWh) model. Contact us with your target inverter, enclosure format, and volume for a project quotation.
Why Installers Still Spec 280Ah
- Broad cell supply: the LF280K is a widely produced LiFePO4 cell format.
- Installer familiarity: thousands of technicians have commissioned 280Ah-based 16S systems.
- Cost per kWh: typically the lowest cost-per-kWh of any 51.2V configuration.
Decision Framework: 280Ah or 314Ah?
- Choose 280Ah when: budget is the deciding factor; your installer team is already tooled on LF280K-based systems; you need maximum supply certainty.
- Choose 314Ah when: maximizing energy per rack footprint matters; the project is a premium residential installation.
- Either way: both are 51.2V 16S with identical charge profiles (58.4V), so inverters and wiring are interchangeable.
Beware of “too cheap” 280Ah offers. The LF280K’s popularity has attracted relabeled B-grade cells sold as Grade A. Genuine Grade A cells carry manufacturer QR codes with traceable batch data — always verify before committing to volume.
Shipping, Documentation & Project Terms
Lithium batteries ship as Class 9 dangerous goods with UN38.3 test summaries and MSDS. Specifications, pricing, MOQ, and lead times are confirmed per project.
Frequently Asked Questions
Is 280Ah being replaced by 314Ah?
Partially — 314Ah is the newer generation with ~12% more energy per pack. But 280Ah remains in active production with the deepest cell supply and longest track record.
How much energy does 51.2V 280Ah hold?
51.2V × 280Ah = 14,336Wh (14.34kWh).
Which inverters are compatible?
The BMS supports CAN and RS485 and can be set to common protocols used by hybrid inverters such as Deye, Growatt and Victron systems. Send your inverter model and firmware version; we confirm the protocol setting, cable pinout and charge settings before shipment. Some inverter brands (e.g. SMA, Sofar, GoodWe) only warranty batteries on their own approved lists, and LJY Energy is not on any inverter maker’s approved list unless confirmed in writing.
Can I mix 280Ah and 314Ah packs in parallel?
Not recommended. Parallel packs should match in voltage profile and capacity. Choose one generation per system.
