If anyone needs a battery rebuild service for the batteries for the LINK strobes, MTO batteries offers rebuild services for those batteries. Just email them regarding the rebuild as it’s a custom quote. I got mine rebuilt and shipped back for 110. You’ll need to ship it to them yourself but USPS allows batteries up to 100ws to be shipped and the link is 72wh.
Update: battery still dies at 1/4 power despite being re-celled I got new batteries from buff for free. Their current stock is a new batch that just came in a month ago.
