The DeWalt Flexvolt 12.0 Ah battery offers up to 50% more runtime than the 6.0 Ah battery that comes standard in most Flexvolt kits and 33% longer than their 9.0 Ah battery. It has the DeWalt traditional 3 bar LED fuel gauge DeWalt FLEXVOLT 12.0 Ah Battery Review Performance The Flexvolt 12.0 Ah battery is 3.8” tall and weighs in at 3.2 pounds. DeWalt FLEXVOLT 12.0 Ah Battery Review Features They are calling it the Flexvolt 20V/ 60V Max 12.0 Ah battery (60 Volts X 4.0 Ah or 20 Volts X 12.0 Ah). In April of 2018, DeWalt released the largest capacity Flexvolt battery to date. If the battery is put into a 60V Max tool, it will automatically be set up in series. If the battery is plugged into a 20V Max tool, the electronic communication between the tool and battery will essentially tell it to set up in parallel. Basically, the tool will determine the battery’s voltage. Now your next question should be, how does the battery know what voltage to be and how to switch between the two? This is where the magic happens. When the Flexvolt battery is configured like this, it is considered to be set up in series mode. If instead of just connecting one row of cells and you connect all 15 cells together, the voltage will measure 60V, but the Amp Hours will be divided by 3 since these batteries are now acting like three rows described above, they are now acting as a single row. When the Flexvolt battery is set up this way, it is considered to be set up in parallel mode. The more rows you connect increases the batteries Amp Hours (Ah). Since each cell measures 4V, if you connect one row of cells together you will get 20V. The battery housing has 3 rows of cells and 5 cells in each row. To explain what I mean by “how the cells are hooked up”, I’m going to use the DeWalt Flexvolt 9.0 Ah battery as an example. How you hook them up though, determines the battery’s voltage. When you connect these cells together, you get one bigger battery. I’ll do my best to explain what makes the batteries so special.Īs we all know, the lithium batteries we using in our cordless tools are made up of multiple lithium-ion cells (batteries) stacked up on top of each other in a plastic housing. For those of you who are unfamiliar with the Flexvolt line or just are unsure of how they work, they are very unique. It is completely different from what the other tool companies are doing. The Flexvolt battery platform is a relatively new line for DeWalt. DeWalt FLEXVOLT 12.0 Ah Battery Review Overview Read on in the DeWalt FLEXVOLT 12.0 Ah Battery Review to find out more. With the recent introduction of the Flexvolt 12.0 AH battery, DeWalt has increased the runtime on all high demand 20V Max and 60V Max tools. The DeWalt FLEXVOLT platform is continuing to grow and become more useful.
