I don't think I will ever understand the difference between 20V Max tools that can't interchange with a FlexVolt battery, vs 20V Max tools that can.
I do understand the concept of a battery that has flexible voltage options, running three banks of five 3.6V cells each, where the banks can be switched to run in series for 54v, or in parallel for 18v with more available current capacity. I understood that part two years ago, when DeWalt introduced FlexVolt.
But I also understood at the time that certain 20v tools could not be run with the FlexVolt batteries, while the some of the newer 20V tools that DeWalt has released within the last couple of years can.
Even on the DeWalt website, there are two categories of cordless construction tools... 20V MAX SYSTEM, and, in a separate category, FLEXVOLT SYSTEM.
Are there some 20V Max tools that will not run on a FlexVolt battery?
