SUNKKO equalizers, such as the BAL-8624, are compatible with high-capacity ternary lithium battery packs and lithium iron phosphate (LiFePO4) battery packs.
Jeżeli pojemność baterii litowo-jonowej trójskładnikowej wynositage 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.
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.
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).
