Fast-charging technology allows for more efficiency while shortening charging times. That is why Grepow Inc. has started utilizing a new formula, NMC 532, with the cathode that is composed of nickel, manganese and cobalt in 5:3:2 ratio, which ultimately allows the batteries to have a 5C fast-charging rate. Combined with our stacking technology and tried-and-testing manufacturing process, these new battery packs are made to be safer and more stable than ever for UAVs. OEM and ODM is being accepted for custom orders.

The diagram above illustrates how a Lithium-ion Polymer (LiPo) battery is charged in a constant current charging process for fast charging. When the voltage reaches the upper limits, it is adjusted to constant voltage charging to make the battery charge saturated.
A fast-charge battery is a battery that can be charged to 80% or 100% in a short period of time. The technology changes the electrolyte formation to allow the battery to withstand a higher current and quick, full charge.
Throughout the process, different standard charging currents are available for different batteries. For example, 0.1-0.5C is generally selected for 3C batteries while 1C is generally selected for high-power batteries. Choosing a lower charging current also takes the safety of the battery into consideration. The usual fast charge charging current is several times higher than the standard charging current.
