MODEL OVERVIEW
BK Custom Wide-Temperature Lithium Cells — Selection & Sourcing
BK Energy offers a project discussion for custom wide-temperature lithium cell requirements. The supplied material describes multiple chemistries, cell designs and finished packs. It does not establish a single interchangeable cell with one common operating range.
The −80°C to +150°C envelope is a series-level promotional scope, not a specification for this custom product. Illustrations separately show −80°C to 20°C, −40°C to 60°C and −20°C to 150°C designs. These windows must not be combined. Charge, discharge and storage limits need separate written approval for the selected design.
The customization minimum order quantity in the supplied document is 5,000 cells. Sample arrangements, tooling, chemistry, qualification, lead time and price are subject to project confirmation and quotation. Future approved models may use BK-WT plus dimensions and capacity; no unverified model is assigned here.
TECHNICAL REFERENCE
Specifications & Operating Conditions
Read each value with its test conditions. Confirm the applicable document revision before design approval.
| Product type | Custom wide-temperature lithium cell inquiry; no fixed SKU |
|---|---|
| Customization MOQ | 5,000 cells, per supplied document; other commercial terms by quotation |
| Chemistry / format / capacity / voltage | Project-specific; not yet defined |
| Charge temperature and rate | To be agreed for the selected cell; no series-wide charge range |
| Discharge temperature and rate | To be agreed separately from charge conditions; −80°C to +150°C is not a single-model specification |
| Storage temperature and duration | Not specified for a selected cell; confirm SOC and time |
| Capacity retention / cycling | Supplier examples at extreme temperatures are not transferable guarantees. Obtain the exact sample ID, current, cutoff, conditioning and report. |
| Claims awaiting verification | Material cites high-temperature rates, rapid charging and cold start across different examples; model linkage and independent reports are absent. No military qualification or no-fire guarantee is claimed. |
| Technical scope | Define duty cycle, pulse load, service life, dimensions, mass, environmental sealing and system validation in the project brief |

APPLICATION REVIEW
What to Check for Your Pack
Possible evaluation directions only, not confirmed applications or customer projects. A wide-temperature cell does not validate seals, electronics, connectors or charger performance across the same range.
- Energy and load: usable energy, continuous current, peak duration and charging opportunities.
- Mechanical and thermal fit: the exact drawing, connections, enclosure temperature and cooling arrangement.
- Qualification: a test plan based on the finished equipment, including its protection settings and required approvals.
PROCUREMENT DOCUMENTS
Datasheet, Traceability & Certificates
Ask for the specification and drawing that match the offered lot. If your project needs a UN 38.3 test summary, SDS or a particular cell certificate, include that requirement in the enquiry.
BUYER QUESTIONS
Before You Order
Does every option operate from −80°C to +150°C?
No. This is a promotional envelope spanning multiple examples, not a rated range of an individual cell. Request separately approved charge, discharge and storage limits for the chosen design.
What is the customization minimum order?
The supplied material states 5,000 cells. Samples, development costs, delivery, warranty and all other terms require a project-specific quotation.
Which model should I put in the RFQ?
Use BK Custom Wide-Temperature Lithium Cells and describe chemistry preference, dimensions, capacity, temperature-time profile and electrical loads. A BK-WT identifier will be assigned only when a concrete design is defined.
