Help: Onboard battery soldering location?

[MarcPaquette]

Kind of issue? Assembly

Which Board? RGB

Which Board Revision? RGB = 2.1

What steps have you taken

• [x] I have searched the Issues page
• [x] I have read the documentation
• [x] For LED issues I have checked the following things
  • the pro micro is programmed (and currently telling the LEDs to do something)
  • the pro micro is powered (and showing LEDs)
  • the LEDs are powered (check 5v across pins 1 and 3 of J1)
  • are any of the LEDs showing

What is the issue? I'm running a Nice!Nano V2 using ZMK firmware. I'm using this as a Bluetooth keyboard with wireless connectivity between the two halves successfully for about 2 years now.

My question is this: Is there a place on the PCB where I can solder battery connections or must it be done on the Nice!Nano only?

My apologies if this is a silly question, my knowledge of PCB's & Schematics is limited
