From cells to finished packs
Our battery quality process
02
Cell grading
Charge and discharge grading measures cell capacity and performance so cells can be assessed before pack assembly.
03
Sorting & matching
Cells are sorted and matched using relevant electrical parameters, including capacity, voltage and internal resistance, to support consistency within a pack.
04
Pack assembly & interconnections
Matched cells are arranged for the required voltage and capacity. Interconnections, insulation and mechanical fit are checked during assembly.
05
BMS integration
The Battery Management System is selected for the pack chemistry, configuration and current requirements. Wiring and sensing connections are checked.
06
Enclosure & protection
Connections, insulation and enclosure fit are reviewed. Potting or additional protection depends on the model and application.
07
Final electrical & functional checks
Completed packs undergo electrical and functional checks before dispatch. Model-specific charging, discharging and BMS checks form part of the quality process.
08
Labelling & dispatch
Battery specifications, handling information and applicable warranty details are reviewed before packing and dispatch.
Transparency in components
Know the cells and BMS in your battery.
We are transparent about the cells and Battery Management System used in our packs. We select quality components suited to the chemistry, current requirements and intended application.
Ask our team for the cell make, model and grade, battery chemistry, pack configuration, and BMS type and protection features for the model you are considering. Component specifications can vary between products and series; confirm them in your quotation before purchase.
Safety is part of the design and assembly process.
Cell selection, matching, insulation, secure interconnections and a compatible BMS all contribute to battery safety. Protection features and operating limits are model-specific. Use the specified charger and follow installation and handling instructions.
Any certification or compliance documentation should be confirmed for the exact battery model and application. Contact us for available documentation.
