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.
Faster Charging:
Supports 3C - 5C fast charge. Charging speed can be increased by 60%

Single cell cycle 1000+ cycles with 90% capacity retention rate. Usage increases by 50%
High Energy Density:
Up to 220 Wh/kg. Weights 15% less than ordinary batteries
Effective Price:
More affordable than LCO batteries — save up to 30% in cost
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.
