New and Improved how? According to SOCOM Gear, these new LiPo's are designed specifically for Airsoft guns, and not a rebrand of RC Batteries. Thus they have a higher voltage, and currents whilst using a less hazardous formula.
Designed by SOCOM Gear's in-house R&D Team, and inspected and tested to the highest QC standards, these new Li-Poly Batteries offers a 150% more BBs per second!
