Leszek talks about the popular airsoft battery models from Electro River that can best fit your airsoft gun in this Gunfire video... "Electro River is a new quality on the LiPo package market. This manufacturer set itself the task of creating a product whose quality matches the best players on the battery market while maintaining an attractive price. The offer includes very capacious packages as well as those designed with limited space for power supply in mind - even packages the size of a lighter! In the video, Leszek checks exactly which batteries fit the replicas. When purchasing an identical set, you can be sure that you will fit the Li-Po pack."
