Controlled pack assembly for OEM and industrial projects once cells, architecture, and drawings are locked—matching, welding, BMS integration, harness, enclosure, validation, and shipment documents.
Capabilities
Custom battery pack assembly starts from approved cell models, drawings, series-parallel configuration, BMS requirements, connector definition, and test criteria. Incoming appearance, batch, voltage, and internal-resistance information are checked before production.
OCV / IR matching, cell coding, polarity, spacing, holder, busbar or nickel layout, and current path are confirmed against the approved pack specification. Standard battery pack assemblies follow locked series-parallel, enclosure, and BMS interfaces when the specification is already fixed.
Spot welding or tab connection, insulation paper, tape, spacing, compression, vibration protection, and mechanical fixing are controlled by the approved assembly drawing and process limits.
BMS integration service covers BMS installation, temperature sensors, fuse position, communication harness, power leads, connector pinout, enclosure fitting, and service access checked against the host equipment interface.
Projects can include polarity, insulation, BMS function, communication, charge-discharge, aging, appearance, label, packing, traceability, and shipment-document checks defined by the approved test plan.
How to choose
Controlled assembly for approved specifications. If cells, series-parallel layout, BMS, enclosure, or validation still need development, begin with a custom design review.

For projects requiring cell selection, electrical architecture, BMS, mechanical design, prototype, and validation development.
Open custom design →Controlled assembly
For teams looking for battery pack assemblers with approved cells, series-parallel layout, drawings, BMS, connector, and test requirements.
Review assembly scope →Manufacturing proof
Review incoming inspection, OCV / IR matching, insulation, controlled assembly, BMS integration, inspection, traceability, and documentation planning.

Typical work includes cell matching, series-parallel assembly executed to the approved drawing, spot welding or tab connection, insulation, BMS integration service, harness and connector assembly, enclosure fitting, functional testing, aging, labels, and shipment document planning.
Simply provide your key requirements (such as voltage, capacity, peak current, enclosure constraints, and target volume), and our engineering team will help finalize the full technical specifications for you.
Yes. The assembly route depends on the cell format, discharge current, pack voltage, enclosure constraints, and validation target.
Choose custom design when cell selection, series-parallel layout, BMS, enclosure, connector, or validation still need engineering. Choose assembly when the specification and drawings are ready for controlled production.
