“The best battery for karts I know and I’ve owned quite a few. It protects, conceals and hits like a dream. Only drawback is the haptic technology. If you stop drawing and then immediately draw again. It will go into preheat mode every time your done with your hit. If you don’t pay attention and put it in your pocket right away it’s preheating in your pocket then. Burning up a little of your kart each time. Just pay attention and hit the button on the bottom once. It’ll stop preheating then. Other than that love it. Very very smooth!”
