Applications/Examples of results
- It is very dangerous to collapse from heatstroke. We recommend preparing a helmet fan as a measure against heatstroke. Note 1: On our product page for lithium batteries, we sell two types: flat head and pointed head. Please purchase the flat head for helmet fans HF3 and HF4. Additionally, the pointed head φ18*70mm is commonly sold in general shops, and if you buy it unknowingly, it will be 5mm taller and cannot be attached to HF3 and HF4. Note 2: For flat head 18650 batteries, judging the polarity based only on the outer shape can lead to mistakes. Be sure to check the printed "+" symbol to determine the positive side. Quantity Service: When the order quantity is substantial, we will ship a deluxe version with additional optional parts included.
