Product Description:

【Installation and Usage】:
When installing the adapter, a reassuring "click" sound signals the correct and stable connection after the relevant latch system locks. Initial installation may require a moderate push. If you find it unfamiliar to push directly, try pressing the V20 battery latch button first, then insert the adapter to the proper position. Release the battery latch button to swiftly complete the installation. Most tools have an integrated BMS system. To ensure the proper functioning of the tool, check the battery level before using the adapter.

【2-Pin Connection Explanation】:
Due to brand-specific charging system differences, the adapter retains a 2-pin connection, removing charging and detection system pins for compatibility.

【Distinguishing Between 18V and 20V】:
Differentiating between 18V and 20V MAX batteries is essential. Most 18V or 20V MAX battery packs consist of the same configuration of 5 "18650" or "21700" cells in series or in multiple layers. The standard voltage of a single cell is approximately DC 3.6V. When these cells are connected in series, the voltage adds up; for example, 5x 3.6V = 18V. Similarly, the maximum power voltage for a single cell is 4.2V, and when connected in series, 5x 4.2V = 21V. In conclusion, whether it's labeled 18V or 20V MAX, these battery packs are composed of the same cell configurations, with no actual difference. The voltage designation varies based on branding preferences.
