Replacement packs for the Darlington STK-0050. I tested these particular ones for 24 hours a day over a 2 week period. This easily put over a years worth of wear on them and they performed flawlessly. Also hooked them up to a scope and tested the output power and they performed great there as well. That video is coming soon and will post here when complete. 

Here's the video link below so you can buy with confidence.
