Product Description:

【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.

【No Charging Capability】:
Due to its interface with batteries from different brands with distinct communication systems, this adapter does not support charging. It utilizes 2-PIN connectors for Ridgid battery power supply only.
