Recognized component; not a complete system. UL LLC Certificate of Compliance MH66008, report reference MH66008-20230621, date 2023-June-22, issued to Shenzhen Wirentech Co., Ltd., for "BATTERIES FOR USE IN STATIONARY AND MOTIVE AUXILIARY POWER APPLICATIONS - COMPONENT"; its addendum page names "Battery Module for Use in Stationary Applications", model WT5100. The model was evaluated to the component requirements of ANSI/UL 1973: the certificate says UL Recognized components are incomplete in certain constructional features or restricted in performance capabilities and are intended for installation in complete equipment, so this is a component recognition, not a listing of a complete energy storage system. The standard is recorded exactly as the certificate prints it (no edition printed). No expiry date is printed. Read from the issuer's certificate document as Wirentech serves it on its User Center page, captured October 27, 2026; the certificate's current status was not checked in UL Product iQ (blocked to the research fetcher). Recorded as a manufacturer-hosted certificate: the issuer check remains open. The California Energy Commission list reports the same certificate date for WT5100 (recorded separately).
Finished battery pack / module. A test report, not a certification or listing. UL 9540A module-level test report ("MODULE TEST REPORT") for module model WT5100 (51.2V 100Ah, 16S/1P, REPT BATTERO CB56 LFP cells), project number 4791039021, date of issue 2024-03-12, UL Report Office UL(Changzhou) Quality Technical Service Co., LTD, applicant Shenzhen Wirentech Co., Ltd., UL 9540A 4th Edition (November 12, 2019), Section 8 module level test, run at South China Testing and Certification Co., Ltd. The report prints: the initiating cell went into thermal runaway and propagated to at least four adjacent cells; no flaming and no external flaming occurred; no flying debris; the effects of thermal runaway were contained by the module design, but the cell vent gas was flammable, so the module-level performance criteria were not met and "unit level testing in accordance with UL 9540A will need to be conducted on a complete unit employing this module." No unit-level report was published with it. The report says it in no way implies Listing, Classification or Recognition by UL. UL 9540A is a fire test method; it does not replace a UL 9540 listing. Read from the report as Wirentech serves it on its User Center page, captured October 27, 2026; recorded as a manufacturer-hosted test report. Wirentech's own UL9540A claim on its product page is recorded separately.
Finished battery pack / module. IECEE CB Scheme CB Test Certificate, Ref. Certif. No. DE 7-0791, issued by the National Certification Body TÜV NORD CERT GmbH (Essen, Germany), date 2023-09-27. Product "Li-ion Battery Pack", applicant and manufacturer Shenzhen Wirentech Co., Ltd, factory Huizhou Bohairongchuan Technology Co.,Ltd, ratings "51.2V, 100Ah, 5.12kWh", Model / Type Ref. WT5100. A sample was tested and found in conformity with IEC 62619:2022, test report ref. no. BL-DG2370252-301 (not published). No expiry date is printed. A CB test certificate is an international test certificate, not a UL or North American listing. Read from the certificate as Wirentech serves it on its User Center page, captured October 27, 2026. The IECEE public certificate database (record 1697085, captured October 27, 2026) lists DE 7-0791 for model WT5100, product "Li-ion Battery Pack", rating "51.2V, 100Ah, 5.12kWh", issuing body TÜV NORD CERT GmbH, manufacturer Shenzhen Wirentech Co., Ltd, standard IEC 62619:2022, status "Valid", issue date 2023-09-27. The database record names no test report number, so the report number above rests on the certificate alone.
Finished battery pack / module. CE for the EMC Directive only. A testing laboratory's "CERTIFICATE of Conformity" under "EC Council Directive 2014/30/EU", Certificate No. XK2309013026C, signed for Shenzhen SiCT Technology Co., Ltd. (SiCTLab) on October 9, 2023, applicant and manufacturer Shenzhen Wirentech Co., Ltd, product "Li-ion Battery Pack", Model/Type No WT5100, WT5100S, WT51150, WT51200, WT51280, WT51300 (only WT5100 is this record), test standards EN IEC 61000-6-3:2021, EN IEC 61000-6-1:2019, EN 61000-3-3:2013+A2:2021+AC:2022 and EN IEC 61000-3-2:2019+A1:2021. It is based on a sample, is valid only with test report XK2309013026E (not published) and does not imply an assessment of production. CE marking is the manufacturer's own declaration: this is a laboratory's EMC test certificate, not the EU Declaration of Conformity, and it names no Notified Body and no directive other than the EMC Directive. Read from the certificate as Wirentech serves it on its User Center page, captured October 27, 2026; SiCT's own records were not checked.
Product / system scope unresolved. Model WT5100 listed on the California Energy Commission Battery List (data unchanged since October 21, 2026; downloaded October 23, 2026) under Shenzhen Wirentech Co., Ltd., as "WT5100", CEC listing date 2025-04-11.

Product / system scope unresolved. Listed on the California Energy Commission Battery List (data unchanged since October 21, 2026; downloaded October 23, 2026) as Shenzhen Wirentech Co., Ltd. "WT5100": UL 1973, certifying entity UL, certificate date 2023-06-22, Ed. 3 : 2022, CEC listing date 2025-04-11. A state equipment list entry, not the certification body's own record.
Battery pack claim; verification pending. A manufacturer claim of testing, not a certification or test report. Printed as "UL9540A" in the row "Certifications UL1973, UL9540A, CE, CB, PSE, UN38.3" of the specification table for Model WT5100 on Wirentech's own 51.2V 100Ah LifePO4 Rack Mounted Battery page (wirentech.com), captured October 15, 2026. The same page's Technical Parameters block prints "Certification UL1973,CE,CB,UN38.3" without UL9540A. The page does not say whether the test covered the cell, the module or an installation. UL 9540A is a test method, not a certification; the document does not say who ran the test. No test report number is printed; no report was checked.

I got two batteries early last month, and one of them wasn't in great shape. The handle was bent and cracked, so I contacted them through Amazon. Leo got back to me pretty quickly and offered a solution right away.
Honestly, I wasn't expecting much. I've dealt with sellers before who just pass the blame around or promise to help and then never get back to you. This was a really nice surprise.
Everything was handled smoothly, and Leo was great to work with. Probably the best customer service experience I've had from an online purchase.
