Cybex E-Priam Stroller Smart Features Not Functioning Due to Battery Issues

I spent a lot of money on the Cybex e-Priam stroller because of its cool features, such as the smart uphill assist and rocking mode. I thought it would come in handy when I went for walks with the baby. put it all together and was ready to test these cool features the e-function, which is what makes the uphill assist work, is no longer useful. After following the directions to the letter, the stroller wouldn't even turn on, no matter how much I charged the battery. There was not a single flicker of a light. I understand that the design and other things are nice, but this is not worth the price. The extra features on this fancy stroller were the whole point, but now they're just decorations that don't do anything. It’s a high-end product.
