If you choose a 500kg/h lithium battey recycling line, you can expect a moderate initial investment and steady returns. Typically, the total investment for such a line ranges from $150,000 to $200,000, depending on your required automation and local costs. With average daily operations and a continuous supply of waste batteries, you can achieve payback within 12 to 18 months. This time frame allows you to recover equipment costs before making additional profits, especially if you maintain efficient operations and steady material sourcing.
