48V Lithium Battery Packs

48V in 13S and 14S: what the configurations mean

A 48V lithium battery pack is built by connecting cells in series until the nominal voltage class is reached, then adding parallel strings to reach the required capacity. In our 48V series the specification library holds 13S and 14S reference designs, so the same voltage class can be met with two different series counts.

The series count fixes the pack's voltage window, and the parallel count sets capacity. Both are checked against your current profile and the physical space available in the device before the specification is written. A 13S design and a 14S design are not interchangeable drop-ins; the choice follows the device's voltage limits and charger strategy.

This is why we do not quote a single generic 48V block. The lithium ion battery pack 48V category covers a range of builds, and the right one depends on what the pack has to do in your equipment.

Matching the pack to your discharge current

Discharge capability is not a catalogue figure for this series. The BMS and cell configuration are matched to your continuous and peak current during design, and the resulting current capability is confirmed in the project specification for your build.

Peak current and continuous current place different demands on the cells and the protection circuitry, so both are reviewed together with the load profile you provide. A pack that carries a steady load well may need a different cell selection to survive short bursts.

If your equipment has startup surges, motor inrush or duty cycles with heavy and light phases, describe them in the requirement submission. Protection and management circuitry is evaluated at the same stage, so current handling, safety thresholds and communication options are settled as one design decision rather than added later.

The project flow starts when you submit device, application, available space, voltage, capacity, current, environment and target-market requirements. Cell selection, series/parallel configuration, protection and management circuitry, structure and communication options are then evaluated before any sample work begins.

Typical 48V uses: light EVs, golf carts, equipment

The 48V series in 13S and 14S configurations is intended for light electric vehicles, golf carts and equipment. These three groups share the voltage class but differ in how the pack is loaded, mounted and charged, which is why the specification is written per project.

For light electric vehicles, pack mass, mounting envelope and current delivery during acceleration are usually the defining constraints. Our light EV battery packs page covers how those requirements are handled.

Golf cart demand at 48V is covered separately on the golf cart lithium batteries page, where the duty pattern of cart use and the pack's role in the vehicle are discussed.

Equipment applications tend to be defined by duty cycle and enclosure space rather than by vehicle dynamics. If your device sits below this voltage class, the 36V lithium packs page shows how the same design process works at a different series count.

Across all three, the sequence is the same: samples are developed after the specification and drawings are confirmed, then verified against the agreed test items, and the documentation needed for the target market is checked before production, packaging, quantities, delivery and acceptance conditions are confirmed.

Frequently Asked Questions

Which 13S and 14S configurations do you offer at 48V?

Our specification library includes a 48V series built in 13S and 14S configurations, held as reference designs for light electric vehicles, golf carts and equipment. The parallel count and cell selection are set per project, because capacity and current requirements differ between devices. The exact configuration for your application is confirmed in the project specification after the requirement review.

Can the 48V pack support our discharge current?

The BMS and cell configuration are matched to your continuous and peak current during design. Current capability is confirmed in the project specification for your build, not published as a catalogue figure. To assess it, send your load profile, including peak values and how long they last, together with the device and application requirements, and the design review will confirm what the pack can deliver.

What information do you need to start a 48V pack project?

Submit the device, application, available space, voltage, capacity, current, environment and target-market requirements. From these, cell selection, series/parallel configuration, protection and management circuitry, structure and communication options are evaluated. Samples are developed only after the specification and drawings are confirmed, so a complete requirement set shortens the path to a buildable design.

When does a 48V project move to samples and production?

Samples are developed after the specification and drawings are confirmed. They are then verified against the agreed test items, and the documentation needed for the target market is checked. Production, packaging, quantities, delivery and acceptance conditions are confirmed after that verification stage. To start the process, spec a 48V pack with your requirements and the review can begin.
