(for various reasons I needed to join a mismatched pair of 18v drill and battery, annoyed at how much fun it was)
As long as voltage matches, some batteries at 12v (4S) and others are 24v (6S)
Yes, and also.... Please make a good faith attempt to understand allowable continuous discharge rates for the batteries. (Spoiler: Most battery packs are going to be well within a safe range and may also limit output current.)
For example: If a drill has a maximum current draw of 2 amps and the pack is only capable of discharge rate of 1 amp, you are risking a thermal runaway condition. (Lithium batteries get esplody in those conditions.)
Battery packs generally use a series-parallel wiring arrangement to decrease per-cell discharge and any protection circuits should limit total current draw. Knockoff battery packs may lack protection circuits, but for this specific problem the way the batteries are wired should prevent or limit any issues.
(I get a bit preachy when it comes to battery safety. Sorry. Many people simply do not realize how energy-dense our device batteries are these days.)
