## Questions & Answers

**Q: Why does the flashlight have poor contact after replacing the battery with the extension tube?**
A: Because the battery we use in WUBEN is a battery with a 0.05mm charging protection board (size: 18x70mm), which can increase the safety and service life of the battery;

**Q: What is the function of the extension tube?**
A: It allows us to choose whether to choose different batteries according to our different needs.
