DID WE KILL IT? FLEX Battery and Charger Technology [160W or 280W?] 

Great video. Flex seems to always bring the beans, but those beans always coming served piping hot

280W on a 24V (max) battery is an ~11A charger. That’s consistent with charging a 5A battery in under 30 mins. I think that makes it the fastest power tool battery charger on the market.

that battery is actually 108 Wh. 21.6V x 5.0 = 108 Wh. Never use max voltage to calculate what's SUPPOSED to be a nominal rating. (Flex isn't the only one doing this fwiw, Milwaukee does this on M12 and Dewalt is most famous for it with 20V Max) I think Makita is the only one who offers the correct Wh ratings despite marketing the "Max" voltage for their XGT and CXT lines.

I really like the level of details you go in your reviews! Really like when you're opening them up to see how good or bad they're made! Keep up the good work! :-)

Hard spots in rebar? Is rebar made from melted down scrap or something?

Milwaukee needs fans like these on there string trimmer cause it gets hot and cuts out when you work it hard

what ya mean couple decades you be thinking of dewalt flex just came out this year at Lowe's. 😄

Bought this Flex pack out a few months ago. Used on three projects. The latches between the top box and the middle box kept hanging up or not locking. Soooo, tried to call company service to get a fix. Wasn't asking for anything but a tech to walk me through the fix(maybe a replacement latch?). First, good luck getting through, they DON"T answer their phones. After a half hour hold the message comes on offering a call back. No choice gotta grow old on the phone or give up. No call back, so the next day I try again, same deal, but this time I get a call back. Pleasant young lady hears the problem and takes all my info and says they are sending a new replacement unit!! Of course nothing took place, NO Replacement Unit, No Latches, NO NOTHING!!!! The product seems to be well made except for these few minor issues, however I would never recommend buying a Flex product. They have no customer loyalty.

Flex is like the cousin Eddie of the tool world in my opinion.

The regular kits that you by don't come with that that supercharger that you demonstrated with a dual fan only comes with the high-end models which you have to pay for once again though still try to call flex and register your products with the warranty and you can't even get them to answer the phone and after then try to get them replaced with any luck going to Lowe's and asking them to give you a new tool. I'd rather stay with the black and red send in a tool and got it replaced within a week I had a brand new one delivered to my house

That's Not an easy task! I was wondering if I might need a break before the tool. My Ryobi "smart charger" won't charge a hot battery either. It tests the battery every few seconds until the internal temp reaches a safe to charge temp. It doesn't use cooling fan and I accidentally killed a battery while working on a big project by placing it on charger too soon. I'm just saying the technology has been around for a while if my 9yr old smart charger had the tech for a DIY brand like Ryobi. The need for a cooling fan to cool down the battery when hot at least as important. I'm sure more than a few home fires, and construction sight incidents have occurred due this issue. Flex has made me reconsider what platform I may adopt next. I'm looking forward to the new year, to see who has the latest and greatest tool platform. My Ryobi stuff needs to upscale to something contractor level. Right now, DeWalt's kicking everything else's butt. I don't mean every individual tool available, but for the tools that I use to beat the heck out of on a daily basis in heavy duty body repair facility I work in.

How long does the battery last in a drill?

An hour & 3 minutes for a full charge on a 5ah battery on a “rapid charger” is not to great tbh .30 mins for my Milwaukee 5ah on their rapid charger,bout 45 mins for a 6ah high output .I get its cooling first but idk .15 extra minutes for a battery charge on the site aint gunna cut it

Great review also the best power tools on the market

FLEX IS AWESOME!!!! Great products for real

love my new Flex tools.Invested like 1300.00 in them,which i felt was more then fair for what a got.Buy now and get buy more save more great Deal.Now go and get some u won't be sorry

MY several year old. Kobalt charger does this. I know same company but still nothing new.

My flex rapid charger just exploded first time it worked.

wonder how many cuts and how long it takes when your on a jobsite and its 100 degrees outside instead of a air conditioned shop

I just invested in a Milwaukee supercharger, any idea how the cooling technology compares?

I dropped over $3 thousand dollars in flex tools almost 2 years ago when they were released. 3 months ago the batteries started leaking back goo that stains everything and may be toxic. Flex warranty is nowhere to be seen.

650 and 700mm long? This isn't tinder. I think you meant 65.0 and 70.0 mm long!

I have both chargers that rapid charger is something else

What about the leaking issues when the flex batteries got hot?

How many fans are on the ‘fast’ charger? Is there a dedicated fan for the battery?

All these features except the fan are pretty standard for all lithium ion power tool chargers out on the market

I purchased a new FLEX tool with battery this month. Unfortunately, the battery is leaking fluid.

Does the cheaper charger have dual fans like the rapid charger? And is it possible to charge a 10.0ah stack lithium battery on the cheaper, slower battery charger?

Tha is for a great review Tim. I’d like to import a Flex combo set across the pond to the UK. Can you tell me if the charger is multi voltage seeing as we run in 240v mains? Many thanks

if you cant safely take the battery out and put it on the charger then it is not a shop tool

Got an ego snowblower that came with two 7.5 ah batteries. One year, four uses, now one battery won't fully charge even though charger says it is charged. Now a Flex 2.5 ah battery doing the same thing on its third charge. Tried fast and rapid charger. Also 6 ah stacked lithium on jobsite fan reads one bar, take the battery off, four bars. Not exactly a good battery track record so far. Anyone else having Chevron battery issues?

I got the big boy battery. 1 month later, charger has quit on me. Plug it in it shows red and green light and goes off. Can this be fixed? These chargers are expensive...

At what temperature does turbo shutdown?

You know what would be smart? Those brushless electronic motors have that fan on the back of them that move a LOT of air. Maybe if they used some ducting and ran air through the batteries that would help. Makitas already run air through the battery on the charger.

Your voice and look reminds me of jeff foxworthy
