Please be very careful about buying batteries for your drone. You should be fine if you grab a battery directly from the manufacturer, but third-party units, and the vast range of batteries for racing drones, can be problematic. We'll try to keep this simple: your drone is designed to operate within a certain electrical voltage range. A toy drone that came with a 1S battery runs on 3.7V, if you plug in a big 6S battery, you'll be pumping 22.2V into the drone, which is a potential fire hazard. As long as your drone can handle the voltage (and amperage) you're pumping into it, and the battery is wired and connected properly, we'd guess your battery is not the reason your drone won't fly, look for other physical issues or software limits to get back into the sky. (Also, some DJI drones have chips in the batteries, so there may be a software lock, or a firmware update required.)
