SUNKKO Manuals & User Guides

SUNKKO, manufactured by Foshan Meilide Electronic Co. Ltd, is a prominent brand in the field of battery assembly, testing, and maintenance equipment.

Renowned for their reliable pulse spot welders (such as the 737G and 709A models), SUNKKO provides essential tools for building and repairing lithium battery packs, including 18650 and 14500 cell configurations. In addition to spot welding machines, their comprehensive product lineup includes lithium battery pack voltage equalization controllers, high-speed MCU analyzers, and active balancers expressly designed for ternary lithium and LiFePO4 batteries.

• What types of batteries can SUNKKO battery equalizers maintain?

  SUNKKO equalizers, such as the BAL-8624, are compatible with high-capacity ternary lithium battery packs and lithium iron phosphate (LiFePO4) battery packs.

• Why won't my SUNKKO active equalizer turn on?

  As die ternêre litiumbattery voltage is lower than 2.7V or the lithium iron phosphate battery is lower than 2.5V, the active equalization board will not turn on or start equalization work. This serves to protect the cells from deep discharge.

• Can I use the protection board line directly with my SUNKKO equalizer?

  No. Protective board lines are often only 0.1 square millimeter signal lines and cannot handle large equalizing currents. Rewiring with wire not less than 0.5 square millimeters is required to prevent hazards or poor balancing.

• What is the maximum welding thickness for the SUNKKO 737G spot welder?

  The SUNKKO 737G can typically weld thicknesses between 0.05mm and 0.2mm, depending on the current settings, pulse times, and the type of metal strip (pure nickel vs. nickel-plated).
