DZS Elec6pcs 15CM 9V Battery Snap Connector Clip Lead Wire Experimental Battery Snap Power Cable With 5.5x2.1mm DC Male Plug for Arduino Project or LED Light Bar

A lot of folks purchase Sonicake Effects pedals and for those you have to separately buy a 9v wall wart power adapter for. I thought, hey, I need 9v batteries. I have an off grid gig, and can't use power adapters. So for the price it was worth a gamble. Initially, they did not power the pedals, but once I reversed the polarity (Spliced the Black to Red and Red to Black wires) they worked perfectly. I put the batteries in pill bottle cases with desiccant packs, and drilled a hole through the lid to pass the wire through. As you can see. We have power and the sound check was awesome!

OKEY

Works like they shud only problem is they are way to tight on the batteries terminals damaged a couple trying to change the battery so be easy

If you're using these for guitar pedals, the poles are REVERSED.I will try splicing and soldering the wires so red goes to black and black to red. Not sure if this is a mistake or if Pedals work differently but the POS + NEG are backwards when tested on all my pedals (from 3 different companies)Other than that they seem well made, nothing is loose and when tested backwards they seem to work fine.

Good for any adaptor needing a 9V to female jack
