I have 2 Robo-Tank powerbars for sale that are basically brand new. These are for use with Reef-pi controllers, either DIY or the Robo-Tank controller. I just decided to go a different route. Each powerbar comes with a 3ft power cord and 3ft DB9 cable. I paid $85 each just a couple of months ago without the cables. Looking for $140 shipped for both or $130 local (near Greenwood). I will do 1 for $75 shipped or $65 local.
