I need to light traveling show cases with no AC power available. How do I hook up LED flexible light strips to AA batteries. (I bought 20 led per foot reels and 40 led per foot reels. Single color, not RGB) Can't seem to find a AA or AAA battery holder to hook/solder LED lights to. Plenty of AC to DC converters, but not useful in my situation. Thought about buying battery operated 20 foot, LED string lights, discarding the string lights and using the battery holder contraption for my 5 foot section of LED light strips. Just don't know if that could harm the flexible light strips or give them enough power. Are there any setups like this I can buy?
You can get any number of configurations of AA battery holders. Mouser Electronics, an online electronics distributor has a whole page of them in their catalogue at AA Cell Holders Page from types that can accommodate 1 cell all the way up to 10 cells. Here are a few representative pictures of the ones available.
These are available with solder tabs, wire pigtails or snap fitting connections.
