12V Lithium Battery Packs

Two 12V families: equipment packs (11.1V class) and LiFePO4 units (12.8V)

A 12V lithium ion battery pack is not one product. At this voltage we build two families, and the first question on any enquiry is which one your project belongs to.

The first family is equipment packs in the 11.1V class. These are built to the device: the pack fits a defined compartment, follows the device's current profile, and is specified together with its BMS, connector and housing — a pack that powers a monitor, a sickbed or an industrial instrument.

The second family is 12V LiFePO4 units with 12.8V nominal voltage. These are standalone batteries for storage and motive use. They are selected by capacity and discharge demand rather than by an enclosure drawing. If your equipment runs from a standalone battery rather than a fitted pack, see our 12V LiFePO4 batteries; if the pack must fit inside a product, you are in the equipment family.

State the family at the start of the enquiry and the specification conversation moves faster, because the questions we ask are different for each.

The two families in detail

In the 11.1V equipment family, packs are built in 3S1P, 3S4P and 3S2P designs for sickbed equipment, patient monitors and industrial devices. In each configuration name, the series count sets the pack voltage and the parallel count sets capacity — 3S1P and 3S4P share the same voltage class but differ in runtime. Each model's capacity is listed on its product page, for example the 11.1V industrial pack.

In the LiFePO4 family, the standalone units sit at 12.8V nominal. These units are chosen by capacity class and discharge demand, so capacity choice follows the load and the required runtime rather than a device compartment; the classes are listed on the 12V LiFePO4 batteries page.

Equipment packs are built to the device, so the specification work starts from your current profile and the physical space. For device work, our medical device batteries page covers how a pack specification is derived from the equipment itself.

Choosing between li-ion and LiFePO4 at 12V

The choice follows the application, not a preference for one chemistry.

Take the equipment pack when the battery must live inside a device. An 11.1V-class pack is specified alongside the device's enclosure, connector and BMS, and the parallel count is set to reach the runtime the device needs. Within the family, the parallel count is what changes between devices: a 3S1P layout for a sickbed and a 3S4P layout for a patient monitor sit in the same voltage class at different capacities, each built around its equipment.

Take the LiFePO4 unit when the battery is a standalone block for storage or motive use. The 12.8V nominal units are selected by capacity and discharge demand, not by a compartment drawing.

A frequent source of confusion is the label. A 12V li ion battery pack and a 12V LiFePO4 unit are both sold as "12V", but their nominal voltages differ — 11.1V for the equipment packs above, 12.8V for the LiFePO4 units. Check what your charger and device expect before fixing the family.

UN38.3, IEC 62133 and MSDS documents can be confirmed and provided for specific models — tell us the model you are buying and we will confirm which documents cover it. The plant is ISO 9001 and ISO 14001 certified.

If you are still deciding, ask about 12V packs and describe the device or the load; we will confirm which family fits before any specification is written.

Frequently Asked Questions

Do you have 12V packs for medical and industrial devices?

Yes. The 11.1V equipment family is built for exactly this: 3S1P packs for sickbed equipment, 3S4P packs for patient monitors and 3S2P industrial packs, each with its specification on its product page. Each is specified against the device's current profile and physical space. Tell us the device and we will confirm which standard pack fits or whether a new specification is needed.

What capacities are available at 12V?

It depends on the family. Equipment packs in the 11.1V class come in 3S1P, 3S4P and 3S2P designs, with each model's capacity on its product page. LiFePO4 units sit at 12.8V nominal in several capacity classes, listed on the 12V LiFePO4 batteries page. Equipment packs are built to the device, so the capacity follows your runtime requirement and the available space.
