Self locking battery for drones (like DJI battery)

I have been looking for a while now for a battery to use on a custom multicopter that you can slide in and the battery locks in place, similar like on drones like DJI and others but without any luck. Can anyone point me to a nice solution that can be integrated to a custom drone, for example a 6s lipo or liion with capacity of over 10.000mAh? It would not hurt if that battery has some smart features but that’s not necessary.
