This is a sweet universal battery mount for your Steam Deck! I wanted a mount I could use with a case so I made this, then I also made a version for use on a bare Deck (no case). So BE SURE to order the right version, for use WITH a Case, or the model for use WITHOUT a Case. These are two separate battery mounts.
The mount will hold batteries UP TO 1 thick and there's rubber inside the bottom of the battery compartment to keep the battery from slipping. There's also rubber on the back of the mount to prevent it from slipping on the Deck and makes sure it won't leave any marks on the back of the deck or case on the deck.
This mount DOES NOT fit the Baseus 65W 20000mAh battery! I recommend this battery: ://amzn.to/3d1qwc3 Perfect fit and it's a better bang for your buck.
Both mount versions also include a little removeable kickstand block that allows to two angles of use. it attaches via strong Velcro and works great. Doesn't block any exhaust ports, buttons, etc.
