Industry-leading Efficiency

Studies have shown that the 21700 battery produces more heat during high-current charging and discharging, so the polarization of the battery is correspondingly smaller. At the same time, the energy density can be increased by about 6% due to the decrease in the proportion of inactive materials such as the casing.
