Lantern Battery

What if I connect my adapter to a 24VDC to 6VDC lantern battery in series?
What if I connect my adapter to a 24VDC 6VDC lantern battery in series? O 6VDC potentially several flashlight batteries, stress. If this helps, I'll use for iontophoresis is simply not sure if this is safe. Thanks
You said plug in using the series 4-6VDC flashlights must work properly together. Do not put a flashlight in one high and one low, because all the lantern at the top will burn.
