Quick Answer:
A&S Power's 18650 14.8V 2600mAh 4S1P rechargeable lithium-ion battery pack is supported by a multi-document compliance package covering UL2054, CB, CE EMC, PSE, UN38.3 and MSDS.
The battery pack uses 18650 lithium-ion cells in a 4S1P configuration and provides a nominal voltage of 14.8V with a typical capacity of 2600mAh. The current product specification lists dimensions of approximately 20 × 75 × 72mm and a weight of approximately 190g.
For OEM customers, the combination of a compact 4S1P configuration and documented safety, EMC and transportation compliance can provide a useful starting point for battery-powered equipment development.
A&S Power 18650 Battery Pack Receives Multi-Standard Documentation
At A&S Power, I find that certification becomes increasingly important when a battery moves from prototype development into commercial production.
Electrical specifications such as voltage and capacity tell an engineering team whether a battery can potentially power a device. Certification and testing documentation provide another layer of information for safety, regulatory and logistics reviews.
Our A&S 18650 14.8V 2600mAh battery pack is designed as a rechargeable lithium-ion battery pack using a 4S1P cell configuration.
The current specification lists a typical capacity of 2600mAh, a nominal voltage of 14.8V, a 16.8V charge voltage and a 12.0V discharge cut-off voltage. The maximum continuous charge and discharge current are specified at 2600mA.
The product documentation also identifies a DC5521 connector, approximately 100±10mm wire length and a pack size of 20 × 75 × 72mm.
Certification Details of the 14.8V 2600mAh Battery Pack
UL2054 Certification

| Report Reference | MH61634-20240607 |
| Issue Date | 2024-06-17 |
| Standard | UL 2054 |
UL Solutions identifies UL2054 as the Standard for Household and Commercial Batteries and lists UL2054 among the battery safety standards used for battery testing and certification.
For customers who need to verify the certificate, UL Solutions provides a certificate search interface that supports searching by an exact certificate number.
For this product, customers can use:
Certificate Number: UL-US-2424130-0
as the starting point for their certification review.
CB Certification
| Item | CB Information |
|---|---|
| Ref. Certif. No. | DK-128410-UL |
| Standard | IEC 62133-2:2017 |
| Amendment | IEC 62133-2:2017/AMD1:2021 |
| Test Report | P22041802501 |
| Date | 2022-06-06 |
IEC 62133-2 is relevant to the safety evaluation of secondary lithium cells and batteries used in portable applications.
For OEM customers working with international markets, CB documentation can also provide useful technical evidence during supplier qualification and compliance reviews.
CE EMC Documentation
| Item | CE Information |
|---|---|
| Standard | EN 55032:2015+A1:2020 |
| Standard | EN 55035:2017+A11:2020 |
| Report No. | BTL-EMC-1-2403G084 |
I recommend treating this documentation as part of the overall compliance package rather than presenting the CE mark alone as evidence of every aspect of product compliance.
For an OEM project, the final regulatory requirements should always be reviewed according to the complete finished product, intended market and final configuration.
PSE Declaration of Conformity
| Item | PSE Information |
|---|---|
| Report No. | P25030414001 |
| Reference No. | P25030414001 |
| Date of Issue | 2025-04-29 |
This documentation can be useful for customers evaluating battery products intended for Japanese market applications.
As with other regulatory documentation, the exact PSE requirements depend on the final product, configuration and applicable Japanese regulations.
UN38.3 Transportation Test Report
| Item | UN38.3 Information |
|---|---|
| Report No. | BTL-UN-1-S2403G084 |
| Date of Issue | 2024-04-28 |
UN38.3 testing is particularly important for lithium batteries because transportation requirements need to be considered when batteries are shipped internationally.
For OEM customers, having the transportation test documentation available can make it easier to prepare shipping and dangerous-goods documentation with logistics partners.
MSDS Documentation
| Item | MSDS Information |
|---|---|
| Report No. | BTL-MSDS-1-S2403G084 |
| Date of Issue | 2024-04-28 |
The MSDS/SDS provides information used for handling, storage, transportation and chemical safety communication.
I recommend keeping the MSDS together with the UN38.3 report and other technical documents when preparing a complete battery compliance package.

What Does 4S1P Mean?
The 4S1P configuration means four 18650 lithium-ion cells are connected in series. This configuration increases the battery pack voltage while maintaining the capacity of the individual cell group.
For this product, the nominal voltage is 14.8V and the specified charge voltage is 16.8V.
Why Battery Certification Matters for OEM Customers
Certification documentation can support supplier qualification, technical review, market preparation and transportation documentation.
For OEM customers, having certificate numbers, report references and issue dates available makes the technical documentation easier to review internally.
However, battery certification should not automatically be interpreted as certification of the customer's complete finished equipment. Final compliance requirements depend on the complete product, target market and final configuration.
