A cell module assembly includes multiple lithium-ion battery cells connected in parallel and an electronic controller. The electronic controller is programmed to receive useful life data for a useful life indicator of the battery cells, save the life data to memory to create a life data history, determine a life measurement based on the life data history, compare the life measurement to a first end of life threshold, determine if the life measurement has met the first end of life threshold, provide a first end of life output indicating that the life measurement has met the first end of life threshold, compare the life measurement to a second end of life threshold, determine if the life measurement has met the second end of life threshold, and provide a second end of life output indicating that the life measurement has met the second end of life threshold.
