The high discharge rate is representative of the charge and discharge capability of the lithium-ion polymer battery with respect to the ordinary rate. The high-rate battery is divided into a discharge rate and a charge rate, and "C" is used to indicate the ratio of the charge and discharge current of the battery, that is the rate. For example, a 1200 mAh battery, 0.2 C means 240 mA (0.2 mA of the 1200 mAh battery), and 1 C means 1200 mA (1 times rate of the 1200 mAh battery). Normally high discharge rate batteries can be fast charged. However, since lithium ions are embedded in the negative electrode graphite during charging, the process of inserting lithium ions into the positive electrode during the discharge process is difficult, so the fast charge ratio is generally lower than the discharge rate.

The testing battery nominal capacity is 1600mAh, from the discharge curve under different discharge C rate, we can find the 25C performance is the best, but from 30C to 40C discharge rate, the Grepow LiFePO4 high C rate battery still can provide more than 93% discharge efficiency.
Under charging at 1C and discharging at 25C, the high C rate LiFePO4 battery performs an outstanding cycle life performance. From the sheet, we can know there have more than 94% capacity retention rate after 300 cycles.
High performance in power, discharge, and life cycles due to stacking process.
Ability to achieve 150C pulse, 90C discharge for 2seconds, 45C continuous discharge, and 5C fast charging.
Provides better temperature stability and tolerance due to the allowance of higher discharge rate.
