Our Large Cell Features & Benefits:

Advanced Heat Dissipation

JKPower’s SPLB cells dissipate heat much more efficiently than comparable cylindrical or prismatic cells due to their increased surface area to volume ratio. Maintaining temperature within the battery cell is crucial for optimal performance.Advanced Heat

Low Internal Resistance

JKPower’s SPLB cells are manufactured using patented Z-fold design techniques, providing unparalleled low internal resistance which means more power. Low Internal Resistence

High Efficiency

The low internal resistance and optimal design properties of JKPower’s SLPB cells makes them the most efficiency lithium ion cell on the market, reducing operating costs across the board. High Efficiency

Long Cycle Life

Our quality, material, and reliability testing allows us to achieve maximum cycle life in all of our cells. With lifespans upwards of 5,000 discharge/charge cycles before reaching 80% of the cell’s original capacity, your devices will run longer with fewer battery replacements.
