10S1P 36V 3500mAh 18650 Battery Pack FAQs
Is this battery suitable for high-duty cycles throughout a workday?
Yes. The 18650 cell selection prioritizes cycle life and load stability. For manufacturers whose tools run multiple cycles per day, the pack maintains capacity retention and voltage stability, reducing downtime and maintenance.
What if my tool requires a different voltage, capacity, or discharge rate?
Power tool manufacturers often require unique combinations of capacity, power density, and size. CMB can redesign the cell configuration (series/parallel), BMS parameters, and mechanical structure to match your specific performance targets.
What support is provided during integration into our tool design?
CMB provides 3D models, wiring diagrams, connector drawings, and engineering guidance to help your design team integrate the battery pack smoothly into prototypes and production units.
Can this battery pack handle the sudden torque spikes common in milling or cutting tools?
Yes. The pack is engineered with a discharge profile suitable for applications that experience rapid load changes. The selected cells and BMS can respond quickly to short bursts of high current without causing voltage drops that would interrupt tool performance.
Will the battery fit inside a tool with a tightly restricted internal compartment?
For tooling OEMs who deal with strict housing constraints, CMB can further adjust the structural layout, connector orientation, and insulation materials to ensure seamless integration.
