DEWALT XR FLEXVOLT - The Best New Battery Platform?

Dewalt XR Flexvolt

Running high powered tools from batteries is a dream for many. The ability for a roofer, for example, to work at height with cordless tools is a bonus as it allows him to be free from the constraints of a power cord.

However, when it's time to trim hip joints, for example, he'd be forced to carry an unweildy corded circular saw up to where he's working.

What if there was a battery that would power your high-draw tools just as efficiently as it powers your impact driver, giving you the freedom to work on tough materials where traditionally only a corded tool would suffice?

In 2016 DEWALT launched the XR FLEXVOLT battery system and it promised to be yet another positive step in the evolution of tools.

Here's the Top 3 Things You Need to Know about DEWALT's XR FLEXVOLT System

#1 - It's the Evolution Many of You Have Been Waiting For

Dewalt's UK and ROI managing director said:

"To put this simply, the DEWALT XR FLEXVOLT range is the next chapter in cordless technology. DEWALT is launching a range of tools that are not just extremely powerful – they will also provide in excess of a full day’s runtime on single charge for most users.

The potential for this technology is limitless: for each and every trade."

#2 - It's a Convertable Battery Platform - the World's First

The new batteries are both 18v and 54v and they're completely backwards compatible with all of DeWALT's massive 18v XR range. The company promises that slotting one of these new XR batteries into your 18v cordless tool will give you "unbeatable runtime".

The battery has the option to "amplify its voltage" to an unprecedented 54v, meaning they can be used on big, heavy duty construction tools.

#3 - They Hold Lots of Charge

The new batteries, as well as being dual voltage - higher power when your tool needs it - are also 6Ah, giving you charge to spare when you use them in lower draw tools such as drill drivers. Partner them with a brushlesscordless tool, and you probably won't need to charge the battery at all during the day. There's even a suspicion that they'll give your 18v tools a bit of a power boost...

What prevents many of the corded tools we rely on daily to make the switch to battery power is simply the draw from the motor is too high.

Whether it's large diameter grinders, alligator saws or table saws, current technology implies that we need corded versions in order to perform the big jobs.

DeWALT is making no secret of the fact that it believes the new FLEXVOLT XR platform should abolish that mindset. That's because of the new range of tools they're releasing that will take full advantage of the world's first convertable voltage battery.

The company launched the following heavy-duty construction tools that they state are "heavy duty solutions that remain compact and durable".

Let's take a look at 4 of them.

Hi there. I've just purchased the 20v DCD996 drill with a 2016 flexvolt 20v-60v battery. I was wondering if this new 2017 flexvolt18v-54v battery is also compatible with the 20v range tools?

I have just seen on your website that the batteries are going to be around £130.00 a piece, which doesn't sound to bad to be fair, but do you also have to buy a special charger for them, or can you charge them on the usual Dewalt DCB105 charger please ?

Talking to a dewalt guy yesterday, batteries only around the £80.00 mark and he reckons barely any heavier than a 18v 5ah!! Made a big thing about them being designed to work with existing 18v cordless range as to not annoy dewalt fans. Seems very impressive!!

£130.00 plus VAT, a bargain

Great piece as usual Mark.
I was expecting something good from DeWalt as I had seen other companies coming out with 6ah batteries - but this looks like it is going to blow them away, which is brilliant as I am a mad DeWalt fan.
Three questions, any idea how much the batteries are please, my guess would be about £250.00 a pop ?!?
Also, do you know if you will be able to buy the tools 'bare' - as you can with the 18v XR stuff ?
Maybe it's time to get some tools listed to put towards some new ones..
And finally, the batteries look big and heavy, any ideas what they weigh/the size of them please ?
