Nerf Stryfe/Desolator/Rayven overvolt kit
3 lifepo4 batteries and one dummy battery add more volts to your blaser for higher performance. These simply replace your regular AA size batteries and are perfect for when you are not ready to replace motors, rewire, or add lipo power. While not as ideal as full rewire and motor swaps, these will transform any ordinary styfe to be much much better. We highly recommend twisting the thermistor so that it doesn't get tripped under extended use. https://www.youtube.com/watch?v=zQqRmUO0nE
Pay close attention to not over discharge and charge them before battles and they will last a long time.
