I was trying to mount an external battery plate [to the bottom of the Ronin-M Part 17 Remote] and accidentally drilled into the Ronin-M's internal 3S battery. It started smoking immediately. Whoops.
What is the part number, or a suitable replacement, complete with power cable? All of my googling has failed. :/ I am aware that a replacement for the whole unit is $100, but I don't need anything other than the battery.

Thanks!

Does anyone have a replacement battery option for the Ronin-M remote?
