Each battery pack will have about 10-feet of wire between the battery pack and the first set of lights. As seen on Making The Cut. We have taken several long strands of conventional LED light strands and combined them to make fabulous 10-ft, 7-ft, 5-ft, and 3-ft down strands of lights with beautiful warm white LEDs. I handmake these units. All units on this page are battery-operated. Because batteries offer limited power, we can only power 2 down strands per battery pack. Our other tree hanging options offer 110V power for times when you need more strands. These battery options are perfect when plug-in power just isn't an option. The battery pack option is powered by 3 AA batteries. The battery pack comes with 3 different modes of operation: On, Timer, and Off. The battery pack can run one or two down strands. Again, there is no remote control with this option.
