Highly recommended! Holds 8-AA batteries (these last much longer than one 9-volt battery). Creates 12-volts. Use this 8 AA Battery Cage instead of a 9 Volt Battery when powering a 9-14 volt driver (including the sound-activated driver) or the 10-channel sequencer. 8 AA batteries = 12 Volts Increasing the voltage applied to your NeonString wire will increase the brightness and allow you to light a longer section of wire. 8 AA batteries will last MUCH longer than a single 9 Volt battery, so you can stay glowing bright all night long!
