Pillar 91D3K2 24Ah pouch cell

What the official reference establishes

The official table gives 91D3K2 a nominal capacity of 24Ah, dimensions of 9.0 × 133 × 202mm in T × W × L order, a mass of 530g and a listed voltage range of 2.75–4.2V. Its chemistry column reads 磷酸锰铁锂, a manganese-containing iron-phosphate description. This is retained as supplier wording rather than silently treating the cell as the same chemistry and voltage specification as A9D3K2, 78D3K2 or 94D3K2.

Define the work before choosing a configuration

The similar footprint and near capacity do not make 91D3K2 a direct replacement for the 25Ah 94D3K2. The source has a materially different voltage-range entry. Ask for the current chemistry designation and approved cell datasheet, plus BMS, charger and system-engineering review of the complete proposed assembly. The listed range is recorded for identification, not as a user-set charging, discharge or balancing procedure.

Keep the supply package explicit

The catalogue cycle figure differs from the LFP rows, but the complete test method, temperature and end-of-life definition are not supplied. Do not compare service life as if the conditions were identical. Request application-specific technical data and report scope. A general forklift or AGV application heading does not establish a complete 91D3K2-based battery, its enclosure, current capability, vehicle fit or operational safety. The independent illustration explains the shared pouch form only.

Questions for the proposed product

Is the offer a cell, module or complete battery?

State the complete cell code, revision, quantity, manufacturing lot and exact supply boundary. A cell table does not establish an enclosure, BMS, charger, wiring or complete forklift battery.

What is needed for a technical match?

Provide the vehicle and installed battery identity, intended duty and environmental conditions to the responsible battery engineer. Request the current drawing and complete cell specification, with separate review of any proposed assembled system.

Which documents and commercial terms need confirmation?

Confirm the contracting entity, exact model coverage of reports, transport documentation, availability, lead time, warranty and integration responsibility. Catalogue standards and cycle figures do not independently establish certification, stock, compatibility or service life.

From product research to a comparable request

Prepare a written requirement separating loose cells, modules and complete batteries. Preserve the full cell code, current drawing and specification, test conditions, quantity and documentation. Have the responsible technical party review the entire proposed battery, vehicle, BMS and charger combination. Existing supplier and procurement tools remain below; viewing or following links does not itself send an enquiry.

Sources and evidence boundary

The official contact-page snapshot identifies 浙江桓能芯电科技有限公司 at Building F, 189 Qiantangjiang Road, Jiashan, Jiaxing, Zhejiang. The Chinese site links to en.epillar.com and both product-table images have identical hashes. Direct live HTML requests returned a server-side parse error during this review; the web-reader body snapshot and the directly readable official static table are distinguished in the research record. The shared cell visual and six named table rows support cell discovery, not proof of complete forklift packs, current stock, certification, approved fitment or factory capability. Broad environmental, safety, lifetime and standards statements are not independently verified here. Request current model-specific documents. No cell assembly, wiring, charging, repair or operational procedures are provided.
