This is an overview and guide on installing the Ally X battery into your ally. Please note this is an incomplete guide and is not ready. Testing still needs to be done to ensure the new BMC will work with the older Ally. We currently have 5 batteries on preorder with a supplier for testing. The back case has progressed to a beta version and should fit the new battery correctly. We will need to get batteries in to verify fitment. Going over the new Ally X pinout the battery cable is using the same connector, however, it’s now an 8-wire pinout vs the OG 7-wire pinout. We are unsure at this time what that will require us to do in order to get the battery to work. Currently, our suppliers do not have an eta so we may have to wait until launch for real-world testing.

Materials needed:

  • This guide isn’t complete and is a work in progress
  • You will need both printed back panel and printed modified paddles.
  • This shouldn’t void your warranty. You can contact customer service for better clarification based on your country, laws, and what’s allowed.
  • The Red “warranty void” sticker on the battery and heat pipe does not void your warranty provided you do not damage anything inside of the device and restore it to a factory original condition before the RMA
  • You will need to self-tap the screws into the printed part, FDM might require heat, SLA will require you to do this before you cure the part.
  • Be extremely careful when removing the back panel screws, paddle, and trigger screws as they can strip!


Installing the printed paddles into the printed shell

  • In order for the new battery to fit we had to make some minor adjustments to the back paddles. This will require you to have a set of paddles printed or you can print them yourself. We plan to offer two stl’s to pick from on YesItsKira’s thingyverse.
  • remove the existing paddles from your original back panel, be sure to be VERY careful as the screws are easy to strip
  • install the printed paddles with the screw and springs from your original paddles into the printed back panel

Installing the battery and printed pack panel

  • Remove back panel
  • Unplug the factory battery
  • Remove Factory 40Wh battery
  • Lay the Ally X 80Wh battery in place
  • Plug-in Ally battery cable into the Ally X battery
  • Test fit everything
  • Close the modified shell and put the screws back in
  • Plug in OEM charger and hold the power button until the screen turns on.
