Yes. Both use DeWalt FLEXVOLT 20V/60V MAX battery platform.
Both records are reviewed against the manufacturers' sources; sources last checked 2026-10-14. Informational only: confirm with the manufacturer before buying.
Why
- ✓ Both use DeWalt FLEXVOLT 20V/60V MAX battery platform.
Good to know
- DeWalt lists FLEXVOLT batteries for its 60V MAX tools (e.g. the DCS578B); 20V MAX batteries aren't listed for them.
- 120V MAX tools take two FLEXVOLT batteries.
- FLEXVOLT batteries charge on DeWalt 20V MAX chargers.
- Ah ratings (e.g., 9Ah) apply in 20V mode; in 60V mode usable Ah is one-third (watt-hours are the same, e.g., DCB609 = 180 Wh).
- DeWalt states maximum initial voltage is 20/60/120V and nominal voltage is 18/54/108V.
