About the battery

​

1. The product uses 12V 23A battery, standard battery, which can be used for about 1 year.
2. We do not include 12V 23A batteries. Because batteries are dangerous goods, international logistics is very expensive, and the package is easy to return. The description has instructions, you can buy it on the platform or locally, and the price is very cheap. Thank you very much for your understanding.
