Every battery in our pack series starts as a prismatic cell — and the cell is where quality is decided. LJY Energy’s standard cell series covers the two generations that matter: the field-proven 280Ah class (EVE LF280K and equivalents) and the current 314Ah ESS standard (EVE MB31, CATL, REPT, CALB, Hithium, Gotion). We supply QR-verified Grade A cells with voltage/IR matching for pack builders, integrators, and distributors building their own brands. This series page maps the cell lineup, the Grade A verification discipline, and wholesale sourcing.
Series at a Glance: the Two Cell Generations
| Generation | Representative models | Nominal energy (per cell) | Status |
|---|---|---|---|
| 280Ah class | EVE LF280K; REPT CB56; CALB L173F280; Hithium HC280 | 896Wh (3.2V × 280Ah) | Field-proven, maximum supply certainty |
| 314Ah class | EVE MB31; REPT CB75; CALB L173F314A; Gotion 314Ah; Hithium HC-314AH | 1004.8Wh (3.2V × 314Ah) | Current ESS standard |
Grade A Verification: How We Prove Cell Quality
Every cell order ships with: manufacturer QR code traceability, voltage and internal-resistance test records for the specific shipment, and a specification sheet matching the exact model shipped. No substitutions without buyer approval.
Who Buys Cells (Not Packs)
Pack builders & assemblers
What they need: matched, documented cells in volume — voltage/IR sorted, batch-traceable. The qualification order is small; the repeat orders are the business.
System integrators (C&I / telecom / solar)
What they need: cells plus engineering support — configuration guidance, BMS pairing advice, and documentation packages for tenders.
Distributors building private-label packs
What they need: a reliable cell supply behind their brand — plus the option to graduate to finished OEM packs.
DIY builders & small-batch buyers
What they need: small quantities (4–16 cells), fast air samples, and honest grade disclosure. The DIY segment — van builders, off-grid experimenters, repair shops — buys the same 280Ah/314Ah cells in 4-cell and 8-cell sets, often graduating to volume orders. We support sample and small-batch orders with the same QR verification and matching discipline as volume shipments.
DIY box kit builders (Seplos Mason–type kits)
What they need: 16 matched cells that actually fit the kit — same model, same batch, voltage/IR sorted. The DIY box kit market (enclosure + 16S BMS + busbars + LCD, cells supplied separately) runs on 280Ah/314Ah prismatic cells: 16S1P = 51.2V 280Ah ≈ 14.3kWh or 51.2V 314Ah ≈ 16.1kWh. We supply the 16-cell matched sets these kits are designed around — QR-verified Grade A, voltage/IR matched, single-batch — plus guidance on compression, busbar torque, and BMS settings. We sell the cells, not the kit enclosures; if you already have the box, send us the kit model and we confirm cell fit.
From Cells to Packs: the Full Chain
- Cells: this series — QR-verified Grade A 280Ah/314Ah prismatic cells, matched and documented.
- Finished batteries: our 51.2V 280Ah, 51.2V 314Ah, 12.8V 314Ah, 25.6V 314Ah, and golf cart series — built on these same cells.
- OEM/ODM packs: custom voltage, capacity, enclosure, and BMS — your specification, our supply-chain coordination.
Wholesale Terms
Cell wholesale is a specification business. Every quotation states: manufacturer, exact model number, grade, quantity, matching tolerances, test documentation included, packaging, and shipping terms. Pricing, MOQ, and lead times are confirmed per project — we do not publish inventory claims.
Lithium cells ship as Class 9 dangerous goods (UN38.3 + MSDS mandatory), typically at reduced state of charge. Sea freight from China to major markets runs 2–6 weeks; samples by air.
Contact us with your target cell model, quantity, and matching requirements for a wholesale quotation.
Looking Ahead: 392Ah and 628Ah Generations
Based on our October 2026 market research, the next cell generation is already documented:
- REPT 392Ah (RP392-CB2C): official datasheet documented (12000 cycles, 6.85kg, 75×182×224.5mm) and retail listings observed — but volume supply and project deployment remain unconfirmed. Labeled supply-pending until shipment or deployment evidence appears. 16S1P = 51.2V 392Ah ≈ 20.1kWh (theoretical configuration).
- EVE MB56 628Ah: mass production confirmed — official datasheet, retail stock worldwide, real tested capacity 670–689Ah, already deployed in a 400MWh utility project. 16S1P = 51.2V 628Ah ≈ 32.2kWh.
- REPT 588Ah: official documentation published but volume supply unconfirmed — labeled supply-pending until retail or shipment evidence appears.
- Our position: we quote only cells with confirmed supply per project — currently the 280Ah, 314Ah, and EVE MB56 628Ah generations. The 392Ah and 588Ah formats are tracked and quoted once supply evidence is confirmed.
Frequently Asked Questions
How do I know the cells are really Grade A?
Three checks: manufacturer QR codes with traceable data, voltage/IR test records for your specific shipment, and a specification sheet matching the exact model shipped.
280Ah or 314Ah — which should I build with?
314Ah for new designs (~12% more energy per 16S pack); 280Ah for cost-optimized builds and maximum supply certainty.
Do you match cells for 16S packs?
Yes — voltage and internal resistance matching is standard on every cell order.
Can I get a single-brand supply (e.g., only EVE)?
Yes — specify the manufacturer and model in your RFQ. No substitutions without your approval.
