14.8V 2600mAh Battery Pack

For OEMs, distributors and equipment makers, the 14.8V 2600mAh Battery Pack is most useful when the device already requires a 4S / 14.8V architecture but needs a stronger energy reserve for longer field use. A true 2600mAh 4S1P pack requires four 2600mAh-class 18650 cells connected in series, giving 38.48Wh nominal energy while keeping the structure compact and simple. The regular envelope is 80 x 20 x 68 mm, with JST as the common connector family. EVE, DMEGC, YCYG or customer-specified cells can be evaluated, but the exact cell model, BMS current, wire and JST housing must be confirmed against the real device before sample approval and mass production.

Key Specifications

Specification note: the 80 x 20 x 68 mm size is the regular reference for this SKU. Final discharge current, maximum charge current, BMS limits, exact 18650 cell model, JST connector version, cable length, polarity, charger setting, finished weight and any certification claim should follow the approved BOM, drawing, technical agreement, PI or contract.

Project Parameters to Confirm Before Quotation

Core Sales Angles

1. Keep the 14.8V Platform While Adding More Runtime Than the 2Ah Version

When a device already uses a 4S input, increasing capacity is often more practical than redesigning the electronics around a different voltage. In that situation, a 14.8V 2600mAh lithium ion battery gives the project a 38.48Wh energy reserve while preserving the familiar 14.8V architecture. The value is not simply a bigger Ah number: it can extend work sessions for inspection tools, portable terminals and field instruments without forcing changes to the charger strategy or system voltage. Final operating time still depends on average load, peak demand, standby consumption and the usable voltage window.

2. 2.6Ah Is a Practical Middle Capacity for Portable Equipment

A larger battery only creates value when the equipment can use the extra energy without creating packaging or weight problems. For many portable devices, 2.6Ah is a useful middle ground between compactness and runtime. When buyers compare a 14.8V 2.6Ah battery pack, the main commercial benefit is that the pack offers about 30% more nominal capacity than a 2Ah version while staying within the same general 4S product family. This can reduce charging interruptions without automatically moving to a multi-parallel structure or a much larger enclosure.

3. A Simple 4S1P Architecture Supports Repeatable OEM Production

A simple cell structure is easier to document, inspect and reproduce across repeat orders. In this SKU, a 14.8V 2600mAh rechargeable battery uses four series-connected 18650 cells, so the finished pack remains 2600mAh while the voltage rises to 14.8V. For procurement and quality teams, that clear architecture makes it easier to freeze the BOM, define incoming-cell requirements and keep future batches aligned with the approved sample. The exact cell brand and model should be controlled in the technical agreement rather than inferred from capacity alone.

Quick Buyer Check

4. 18650 Cell Options Let Buyers Balance Brand, Availability and Performance

Cell sourcing should support the product requirement rather than drive it blindly. A 4S1P 2600mAh 18650 battery can be built around approved 18650 models from EVE, DMEGC, YCYG or a customer-specified brand, provided the selected cell meets the required 2600mAh capacity, current capability and quality target. This gives OEM buyers more flexibility when they need a preferred cell maker, regional sourcing strategy or long-term supply plan, while keeping the final BOM controlled around one approved technical specification.

5. 38.48Wh Provides a Clear Energy Step Up for Longer Field Sessions

At 14.8V and 2.6Ah, the pack stores approximately 38.48Wh. That extra energy can be meaningful in devices that spend long periods away from a charger, especially when the user values fewer battery changes and longer operating windows. A 2600mAh 4S lithium battery pack is therefore a stronger fit for field service, inspection and mobile electronics than a lower-capacity version when the equipment enclosure can accept the final pack. Runtime still needs to be validated with the real device load rather than estimated from Wh alone.

6. Defined Dimensions and JST Interface Can Shorten Sample Approval

The regular 80 x 20 x 68 mm envelope and JST connector direction give the buyer two concrete items to verify before a sample is built. For this 14.8V 2600mAh pack, the mechanical review should confirm battery cavity, cable exit and service clearance, while the electrical review should confirm the exact JST housing, pitch, pinout, polarity and wire length. Freezing those details before production reduces the chance that a technically correct battery arrives with the wrong interface for the equipment.

Prototype Approval Check

Application Value

The strongest fit for this 14.8V 2600mAh platform is portable equipment that needs a 4S voltage window, moderate operating time and a compact battery envelope. Representative directions include inspection devices, handheld scanners, testing instruments, field terminals, monitoring products and custom electronics. The 38.48Wh energy reserve gives this SKU a clear runtime advantage over the 2Ah version, but the final choice should still be based on real load current, peak demand, battery cavity, charging method and required operating time.

Frequently Asked Questions

What cell configuration does this battery use?

It uses four 18650 cells in a 4S1P arrangement. To achieve a true 2600mAh pack rating, the selected 18650 cells must provide 2600mAh class capacity in the approved BOM.

What is the regular battery size?

The regular reference size is 80 x 20 x 68 mm. Final device fit should also include wire exit, JST connector clearance and service access.

What connector is commonly used?

JST is the common connector direction for this model. Exact housing, pitch, pinout, polarity and lead length should follow the target device.

What is the full-charge voltage?

For a conventional 4S lithium-ion architecture, 16.8V is the full-charge reference. The final charger must match the approved cell and BMS configuration.

What is the cycle-life reference?

The product reference is 500 cycles. Because the supplied product information does not define cycle-test current, depth of discharge, temperature or remaining-capacity threshold, those conditions should be added if a formal cycle-life claim will be published.

Can this pack be used in any 14.8V device?

No. Voltage alone does not guarantee compatibility. Load current, battery space, charger, connector, wiring route and required runtime all need review.
