By the description, you expect what? A single battery? Guess agin big boy, they'll give you whatever's on hand. I got a three battery pack. Ya think it fits where my single battery goes? Not even close. Now I've got a redneck adlib to make this stupid ting work. yeah it lights up my night time flag light after charging from the small solar panel. but the back of the compartment is replaced with duct tape instead of the weather proof original cover.
