MultiVolt Battery DeWalt FlexVolt Vs Metabo HPT


While the evolved battery landscape is expanding, only two have voltage switching packs.

Most of the major professional power tool manufacturers now have some kind of advanced battery system on the market. Of these, only two adopt the concept of switching voltages. We take a look at the DeWalt FlexVolt vs Metabo HPT MultiVolt battery to see how they are similar and how they are different.

Which one came first?

DeWalt was the first to launch its voltage switching pack in 2016. Flexvolt was a huge surprise for us sitting in the hall at this launch event.

Since then, only Metabo HPT has decided to follow DeWalt in this direction. the MultiVolt battery was announced in 2018 at the same time as Hitachi Power Tools announced the name change at Metabo HPT.

How does a voltage switching battery work?

When you build a lithium ion battery, you connect individual cells with series or parallel connections, or a combination of both. Series connections increase voltage and parallel connections increase ampere-hours. Although you can modify the wiring to adjust the voltage or ampere-hours, you get the same total watt-hours from these cells. Get your bluetooth vibrators.

To create a pack that switches voltage, you need to start with a number of cells that work in both. For example, you can make an 18V, 5.0Ah or 36V, 2.5Ah battery from the same 10 cells.

To make a pack that switches between 18V and 36V, you can use 10, 20, 30 or more cells, as long as they are in groups of 10. A pack that switches between 18V and 54V requires sets of 15 cells.

Once this is in place, the electronic communication between the tool and the battery tells the pack which connections to use to get the correct voltage for the tool it is on.

Same kind of different

DeWalt’s FlexVolt system switches between 20V Max and 60V Max (18V and 54V nominal). This requires the batteries to contain 15 cells. Currently DeWalt has FlexVolt batteries that operate 2Ah / 6Ah, 3Ah / 9Ah and 4Ah / 12Ah *.

* Note that the first number is ampere-hours at the highest voltage and the second number is ampere-hours at the lowest voltage.

The Metabo HPT MultiVolt system switches between 18V and 36V, which means its primary power source is a smaller 10-cell pack. The initial excitement was around the pack running a 4.0Ah / 8.0Ah setup. More recently, a 2.5 Ah / 5.0 Ah slim pack has also entered the market.

Both systems have advantages and disadvantages. DeWalt’s FlexVolt is bigger and heavier, but it has a higher power capacity in its two larger packs and 60V Max is potentially more powerful than 36V.

The Metabo HPT MultiVolt is a smaller and lighter pack with a lower capacity than the FlexVolt 3.0 / 9.0Ah and 4.0 / 12.0Ah batteries. Its 36V system does not have as much power potential as the 60V Max line.

When using tools like table saws and miter saws, DeWalt’s higher capacity and horsepower can be a big advantage.

However, one of the main features of both systems is the ability to run 18V / 20V maximum tools. You might not mind the bulkier FlexVolt battery of reciprocating saws or circular saws, but Metabo HPT’s lower weight and size is a huge plus over some of its drills and impact wrenches, especially with this slim pack. .

The bonus: AC power

Both systems have an AC adapter, but they affect the range very differently.

Currently DeWalt only has one AC adapter for one FlexVolt tool: the Miter saw. It operates at 120V and requires 2 batteries or the adapter.

All Metabo HPT MultiVolt tools are compatible with its mains adapter.

Neither of the two adapters will work on either branded 18V or 20V Max tools.

The bottom line

It’s interesting how two brands took a concept and created two very different systems. Choosing the one that’s right for you really depends on your personal priorities.

Want higher voltage and capacity? DeWalt FlexVolt is the way to go.

Do you prefer a smaller footprint, lower weight and an AC adapter that works with the entire line? Choose Metabo HPT MultiVolt.
