Description
Hithium LF280K 3.2V 280Ah LiFePO4 Prismatic Cell: overview
The OSM Hithium LF280K 3.2V 280Ah LiFePO4 Prismatic Cell is a 3.2 V / 280 Ah rated prismatic LiFePO4 cell, storing about 0.9 kWh of nameplate energy. It is engineered for home and commercial energy storage, off-grid solar, telecom backup and DIY pack builds.
LiFePO4 (lithium iron phosphate) chemistry is the reference choice for this duty because it is thermally stable, keeps a flat voltage curve across most of the discharge, and tolerates daily deep cycling without the capacity walk-down that lead-acid suffers. Every cell is Grade A, brand new and carries an intact QR code, and each batch is capacity-, voltage- and internal-resistance matched before dispatch — that matching is what keeps a large pack in balance in service. Cells ship with busbars and bolts, and the batch test report is available on request.

Sizing this prismatic LiFePO4 cell for your project
Series and parallel. 16 cells in series give a 51.2 V, 280 Ah string (14.34 kWh) for 48 V and 51.2 V systems; 8S gives 25.6 V and 4S gives 12.8 V. Strings can then be paralleled to reach the bank size your project needs.
Capacity planning. At 0.9 kWh per cell, a 5 kWh wall battery needs about 6 cells, a 10 kWh rack bank about 11, and a 16 kWh bank about 18 — before any derating for depth of discharge.

OEM and ODM customization
Beyond the standard configuration, OSM builds to order: enclosure colour and branding, nameplate and label artwork, packaging, cable and connector sets, communication protocol selection and matched charger or inverter bundles. Send the target specification and the artwork, and the engineering team returns a drawing and a quotation.
Frequently asked questions
How long do these cells last in a storage pack?
The published cycle life is 10,000 cycles. At one cycle per day that is well over ten years of service. In practice the pack life is set by how deep you discharge it and how well the cells are matched and clamped, not by the cell on its own, so build the pack from a matched batch and keep it inside the published temperature window.
Are the cells matched before they ship?
Yes. Capacity, voltage and internal resistance are measured and the cells are grouped into matched sets before dispatch. A matched set needs far less balancing current in service and holds its capacity spread much longer than a randomly binned assembly.
What BMS and busbars do I need for a pack?
That depends on the string you are building — 16 cells in series give a 51.2 V string, 8S gives 25.6 V and 4S gives 12.8 V. Tell us the target voltage, the continuous current and the chemistry of the BMS you plan to use, and we will confirm the busbar, bolt and torque spec with the quotation.
Do the cells come with busbars and bolts?
Yes, the matched set ships with busbars and bolts so the pack can be assembled on arrival. Terminal type, busbar material and the bolt torque spec are confirmed on the order, and customised busbar lengths are available for non-standard layouts.
Do you supply samples and OEM branding?
Yes. OSM supplies single units and samples, and offers OEM/ODM on the enclosure, the label, the nameplate and the packaging. Send the artwork and the target specification and we will return a quotation with the lead time.
How is it shipped and what documents come with it?
Shipments go out as Class 9 dangerous goods with the UN38.3 test summary, the MSDS and the transport documents, packed for sea or air freight. Bulk orders can be consolidated so the container is loaded to suit your warehouse.
