14.8V 2000mah Battery Pack

For OEMs, distributors and equipment makers, the 14.8V 2000mAh Battery Pack is most useful when the device already needs a 4S lithium-ion voltage platform but has limited room for battery expansion. Its four 18650 2000mAh cells are connected as 4S1P, delivering 14.8V nominal voltage, 2Ah capacity and approximately 29.6Wh without adding parallel cell groups. The regular 80 x 20 x 68 mm reference size supports early mechanical screening, while JST, wire length, polarity and BMS settings can be matched to the target equipment. Instead of treating voltage and capacity as the whole specification, HSS reviews load current, charger behavior and installation clearance before the sample is frozen, reducing fit and interface risk before bulk production.

Key Specifications

Specification note: the 80 x 20 x 68 mm size is the regular reference for this SKU. Final discharge current, BMS limits, JST connector version, cable length, polarity, charger setting 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 Without Making the Pack Larger Than Necessary

When the equipment already requires a 4S input, moving to a larger parallel pack can add cost and occupy space without solving a real problem. A 14.8V 2000mAh lithium battery keeps the voltage architecture at 14.8V while delivering 29.6Wh from only four cells. For handheld and portable equipment, that balance can protect enclosure space and simplify installation. Buyers should still size the pack from measured average load, peak current and required operating time, but the 2Ah platform is a strong starting point when the device needs voltage and portability more than maximum runtime.

2. 2Ah Can Be the More Efficient BOM Choice for Compact Equipment

More capacity is useful only when the application can use it. In a fixed enclosure, extra Ah can increase cost, mass and packaging complexity while giving little commercial benefit. A 14.8V 2Ah battery pack is easier to justify when the target operating session fits within 29.6Wh and the device is carried, handheld or installed in a tight cavity. For OEM buyers, this creates a cleaner BOM decision: use the smaller 2Ah platform when it meets the duty cycle, and move to a higher-capacity configuration only when the measured runtime requirement genuinely demands it.

3. A Simple 4S1P Architecture Makes Repeat Production Easier to Control

A simple cell structure is easier to document, inspect and reproduce across future orders. In this SKU, a 14.8V rechargeable battery pack uses four series-connected 18650 cells with no parallel group, so the nominal voltage, capacity and cell count are immediately clear in the BOM. That helps engineering and purchasing teams keep sample and production versions aligned, especially when the same battery will be reordered for an established device. The value is not only technical simplicity; it is fewer opportunities for undocumented changes in cell count, wiring, connector layout or pack geometry between batches.

Quick Buyer Check

4. Familiar 18650 Architecture Supports Practical OEM Integration

For an OEM project, a familiar cell format can make mechanical review and future sourcing easier, but the pack still has to be engineered around the real load. The 14.8V 18650 battery pack uses four 2000mAh cells to create the required 4S platform, while the approved cell model, BMS, nickel connection, wire and JST interface determine the finished current capability. This is why HSS asks for steady and peak load data before quotation. The buyer gets a defined 18650 architecture without turning an unverified cell-current assumption into a product claim.

5. Choose 4S1P When Voltage and Compactness Matter More Than Endurance

A 4S1P structure is deliberately compact: all four cells are used to build the 14.8V voltage platform, with no extra parallel cells added for runtime. For a 14.8V 2Ah 18650 battery, that means 29.6Wh from the minimum four-cell structure required for this specification. This can be an advantage in scanners, meters and inspection equipment where cavity size and weight matter. If the device needs substantially longer operation or higher current margin, HSS should move the project to a larger configuration rather than stretching the 2Ah pack beyond its intended duty cycle.

6. A Defined JST Interface and Pack Envelope Can Shorten Sample Approval

The regular 80 x 20 x 68 mm envelope and JST connector direction give the buyer two concrete points to check before sampling: will the battery physically fit, and will the electrical interface match the device? HSS then confirms the JST housing, pitch, polarity, wire gauge, lead length and exit direction against the PCB or existing battery. This turns the sample into a real fit-and-function check rather than a generic voltage test. For replacement and OEM projects, resolving these details early can reduce rework and create a repeatable specification for later production orders.

Prototype Approval Check

Application Value

The strongest fit for this 14.8V 2Ah platform is portable equipment that needs a 4S voltage window, moderate energy and a small battery envelope. Representative directions include inspection tools, handheld scanners, testing meters, monitoring devices and compact field electronics. For an OEM or replacement buyer, the value is the defined 29.6Wh energy and compact 80 x 20 x 68 mm reference size, which make early fit and runtime screening straightforward. The tradeoff is equally clear: if the equipment has long continuous operation or high peak-current demand, a larger-capacity or higher-current configuration should be reviewed instead of forcing this compact SKU into the wrong duty cycle.

Frequently Asked Questions

What cell configuration does this battery use?

It uses four 18650 2000mAh cells in a 4S1P arrangement, giving 14.8V nominal voltage and 2000mAh capacity.

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 and connector clearance.

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 battery configuration.

What is the cycle-life reference?

The product reference is 500 cycles. Because the supplied product information does not define the cycle-test current, depth of discharge, temperature or remaining-capacity threshold, those conditions should be confirmed before the figure is used as a contractual life guarantee.

Can this pack be used in any 14.8V device?

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