Marsh 9 Posted July 24, 2022 (edited) Please read the article below and go to the last page for the solution.Happy charging and diving Marshall https://scubaboard.com/community/threads/a-solution-to-nauticams-discontinued-na-36331-aux-battery-pack.623313/ Update: the Attom Tech case arrived today and was larger and not as thick as the Kolumb case. The electronics appear the same, but if you can get the Kolumb cases they are easier to file down and get you to 58mm. The Attom Tech case is at 61mm and I'm running out of plastic to file down. I may try to remove the two rubber bumpers I mention in the housing to accommodate if necessary. The Kolumb case works the best.
