An inexpensive wall-mounted battery has the lowest price point without sacrificing quality. Cost-saving designs usually provide a lower-grade lithium chemistry or simply have a more straightforward design that decreases the overall cost of manufacturing. Even though these batteries may lack advanced features, their pricing allows them to maintain market relevancy because they still have some capacity, a reasonable cycle life, and basic safety functions. Affordable models can fit the needs of a homeowner who wishes to acquire an energy storage solution for solar panels or as a backup for power outages, but are limited by financial constraints. Such batteries help expand the user range of energy storage technologies and promote the use of renewable energy and energy-saving technologies in homes.
