This is not a measurement over time, and literally shows the exact amount of torque being applied with each impact of the anvil.Īs you can see from the results, as we increased the pack size - the power levels significantly increased. The T-3000 can accurately measure torque up to 1,000 ft-lbs, and shows instantaneous results which prove “how hard the impact can hit”. Using a DCF899 1/2″ High Torque Brushless Impact Wrench, we verified the “ peak dynamic torque” in forward and reverse on a Skidmore-Wilhelm Electronic Torque Tester. ![]() The main things that we were interested in comparing were the power levels, motor speeds, and overall performance. The voltage of the packs were 100% identical ( 20.5 volts - fully charged & without a load being applied). To find out, we tested three different tools & used 3 different battery packs. When you use a FlexVolt battery on a standard 20v tool, is the tool more powerful? Alternatively, when you install that same battery on a 20v tool, the switch is not activated, and the cells are then wired in series AND in parallel with each other ( 5 cells 2.0ah x 4.0 volts = 20 volts 2.0ah x 3 rows = 20 volts 6.0ah). When 60v tools are attached to it, an internal switch is activated which rewires the internal battery cell connections to link them all in series ( 15 cells 2.0ah each x 4 volts = 60 volts 2.0ah). By doing so, it means that your brand new 60v batteries/chargers will be compatible with the current 20v tools - giving you much longer run-times.īasically when you are looking at a FlexVolt battery, it has two different functions. ![]() ![]() This means that even though Dewalt did release a new line of cordless tools, they did not abandon the previous lineup, which is very typical with manufacturers in the past. Since the FlexVolt packs are dual voltage ( 60v & 20v), they will work on all of the new 60v tools & older 20v tools exactly the same way. With the recent release of the new Dewalt FlexVolt lineup, we decided to take an in-depth look into the actual performance that you will get out of those batteries - and more specifically, if your standard 20v tools will see any increase in power levels by using them. The age old question - Does size matter? When it comes to battery packs, there is more to it than you might think.
