We need to know if you have a sima, or polaroid, as the plug tip is a little different on both.No modification needed, just plug & play & still use the internal battery.
Back up battery power+charging of the internal battery assures you up to 5hrs of constant run time using a sima ( sl-100ir) or polaroid ( PLLED36 ) 36 IR LED Illuminator.
Use 4 duracell or energizer rechargeable batteries only to assure proper voltage and longest run time.
The 4aa battery holder also has an on off switch so you can control it on or off.
Includes a hook and loop velcro adhesive strip also.
