The more you tell us,
the more precisely we reply

If you write this

Company (organization) name · contact name · phone · email

This is how we respond

We reply with the review result and a quotation to the email address you provide.

If you write this

Application (testing / development / research project · sample / exhibition / prototype · special custom build · volume production) and 05 Load (target equipment)

This is how we respond

The purpose and certification requirements change the design direction and schedule. If certification is needed, tell us at this stage so it is reflected in the design.

Custom battery packs are built uncertified (non-certified) by default. Certification (KC · IEC 62133/62619 · UN38.3 · EMC, etc.) does not proceed automatically; it is arranged separately by prior agreement and requires additional test fees and test samples. The basic BMS and protection functions (overcharge · overdischarge · overcurrent · overtemperature), structural insulation and safety design are always included, whether or not certification is considered.

If you write this

Choose the cell type first and the operating-voltage list below switches to that basis. Capacity as e.g. 80Ah / 4,800Wh, current as e.g. 50A or 1kW — writing it as power is fine.

This is how we respond

We select the cell and the series/parallel configuration that meet the required capacity. We work with lithium-ion and lithium iron phosphate batteries.

Where people get stuck

Not sure about capacity → power consumption and run time · not sure about current → power (kW) · not sure about the cell → leave it blank

Enter only the values you know, accurately. Blank items are settled during consultation.

If you write this

If a converter, charger or inverter must go inside the pack, expand the item, tick it and write the rated output like e.g. 67.2V, 5.0A (CC-CV).

This is how we respond

If nothing goes inside the pack, you can leave this blank.

The external shape depends on whether these are integrated, so external dimensions are provided after our engineer reviews the request.

If you write this

Size limit (L × W × H, mm) is for the final product. If nothing is fixed, write No limit. Six enclosure materials are available — high-strength steel housing (default) · lightweight aluminum housing (recommended up to 3kWh) · PVC shrink wrap (recommended for compact packs up to 5kg) · heat-resistant, flame-retardant 3D printing (prototype) · injection-molded plastic (volume production) · other.

This is how we respond

At the quotation stage we determine whether that space can be met. The charge / discharge terminal can be left as Standard (manufacturer selection) — wire specification (SQ and material) is selected automatically from the voltage and allowable current.

Where people get stuck

The size limit is for the final product (case), not the module.

External dimensions are confirmed at the production stage and sent to you. We cannot give exact dimensions at the quotation stage. Dimensions on the quotation include a margin and are marked “excluding protrusions”. Soft packs cannot be dimensioned to 1mm, so if a precise external shape is required, we recommend reviewing it with a sample build first.

If you write this

Operating temperature range; high/low temperature, humidity, vibration, shock, waterproof/dustproof environment; charging requirements; desired schedule

This is how we respond

The operating environment is reflected in cell and BMS selection and in the protection design. Send drawings (CAD/PDF) and existing spec sheets by email after submitting the form.
