Battery for Wireless Controllers

Each wireless controller requires a 3.7v lithium rechargeable battery for wireless functionality. The 301230 110mAh Lithium battery sits comfortably under the controller and can be recharged by plugging the controller into a power source via its USB-C connector. This is a great choice for the Sweep Keyboard. The 402780 1000mAh Lithium battery will last longer before needing a charge, but only fits larger keyboards such as the Corne or Sofle. Please note: we cannot ship batteries anywhere outside the United States. For our international friends, you'll need to source your batteries elsewhere in order to complete your wireless builds.
