The cost of wall-mounted batteries can differ quite a bit due to a few reasons. Some of these include: the battery’s capacity, the brand, the lithium chemistry used (lithium-ion vs lithium iron phosphate), and further features like having a built-in BMS or safety certifications. Premium brands tend to charge a higher price than other brands due to their reputation for quality and reliability. In general though, higher-capacity batteries will usually cost more due to the increase in materials and complexity in manufacturing. Additionally, batteries that have more advanced features or additional accessories may be priced higher. Consumers can find a wall-mounted battery that fits their criteria best by comparing prices from various suppliers, having an understanding of the features and benefits of a product, and analyzing what each supplier has to offer
