How To Double Cordless Power Tool Battery Capacity From 3Ah to 6Ah

[@jeroendullers4961]

This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries batery.repair and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!

[@DavidFMayerPhD]

You make it look so EASY, and I know from experience that this kind of operation is NOT easy.

[@homicidal85]

that spot welder looks amazing

[@ucdailoi]

Great demo. Better than much of what I see on youtube..

[@jackdehaan2267]

No clue as to what I watched, but appreciated the knowledge and skill.

[@saxon215]

As always informative and well documented as well as concise keep up the good work

[@RozelyLindim]

the Idea of spot weld is brilliant. Much better to upgrade battery.

[@JAKOB1977]

Good video.. only thing i misses was perhaps some values about how VTC6 stack up in actual use cases vs original but that would need some hijack of the current wire with RC amp meter or a DC Clamp meter but I reckon likely not the big difference in actual effect as its current limited fx with ESC on power tools with fx brushless. thx for the video.

[@yoshimitsu380]

That spot welding method is great. Thanks for the ideas

[@silversrayleigh8980]

Ya cool spot welder ... however a pre-fabbed spot welder gives some peace of mind ... As long as your still building/rebuilding batteries. I almost expected a bigger 3D printed case coming out the bottom of the original with 21700's in it instead.

[@KBBAKTHA]

Excellent build video has become your hallmark. Happy new year. Thanks

[@davidmiracle398]

Working with Lithium Ion batteries takes me beyond my yellow streak, but.... I loved your video and your skill set. Also your courage in messing with dangerous stuff!

[@weeardguy]

I used to think the same way. But at some point, you open up your first cell-pack or appliance with such cells in them and from that point on, you progress ;) . I now have multiple cells a bit scattered around the room.

[@richmarsh5029]

Brilliant mate.. Awesome work.. Big Thanks from Australia.... and I subscribed as well

[@TheMarcball]

very good video, very clean and sharp approach. And the Arduino spot welder is interesting. Thanks for the inspiration... Keep on trucking (from France) !

[@TheSpotify95]

Nice stuff! Also great that you got a battery spot welder. Though I imagine that such a device wasn't cheap, and for occasional use, soldering would probably be better. I know that your older videos used the soldering approach and worked well.

[@slyztercoreveanged3175]

buy a battery spot welder..then make a service to change older battery pack for folks for half the price of new battery...iam pretty much sure many people will hire you...2-3 job pay the machine...plus he changing the battery from 3 ah to 6 ah and it cost him half the 6ah battery

Bosch moved up to "21700" batteries (~5 Ah/piece) with battery cases nearly the same weight and size. They're awesome, but pricey. Have you tried?

[@giannislymperopoylos5574]

excellent job...these are 15amp continuous max discharge...or 30 with a cut off thermal circuit....most power demanding 18v tools exceed this limit easily at full throttle!!but these and the old ones are unprotected so the protective thermal circuit is already there....i guess!!very clever upgrade...with new 18650 that can have 20-30 amp and 3000mah capacity you dont need a second spare one!!!and great spot welder... especially with the timer delay...looks like an excellent unit...!!thanks for sharing!!! i just saw the specs and the price of the unit....someone used just a solenoid and a battery...BUT THE SOLENOID MUST BE RATED FOR THE BATTERY CCA AMPS AND THE BATTERY SHOULD NOT BE AS HIGH AS HERE...(400A-600A)... CAUSE THERE IS NO CONTROL CIRCUIT BOARD AND YOU CAN EASILY OPEN HOLES ON THE NICKEL PLATES...!!THERE IS ALSO A 300A FUSE ON THIS PARTICULAR ARDUINO UNIT YOU USE...!! also if you add the 90 dollars and the 60 of a 500cca battery you are almost near as here www.ebay.com/itm/788H-Battery-Pulse-Spot-Welder-18650-Battery-Charger-Tester-0-1-0-2-mm-220V/122733520271?hash=item1c937ce58f:g:XVcAAOSwAVxZ0KK6 which without any mosfet mod you go up to 800amps and 0.2 thickness and you dont mess with arduino complexity ...anyway...it looks like a very well built ,reliable AND MOST OF ALL COMPACT unit!!

[@harleyme3163]

ps.. amps and miliamps are the same thing just a different measurement.. and 18650's might have 7 amps of life.. and what he's done is limited that motor to below the recommended voltage.. = less torque.. amps or volts.. cant have both.. essesially the drill will use twice the amps to spin the motor giving him no extra work time either hehe

[@xdeadwrongxdeadwrong7181]

@@harleyme3163 not sure...so he ordered battery's with a larger capacity...so basically holds a bigger charge ..didnt change any specs of the drill itself expect for the charge range...which is now longer than the stock version of it's original design. So your saying he loss efficiency of the motor due to larger battery capacity?

[@LawAbidingCitizen117]

Does this Bosch battery pack has cut off circuit to cut off power when the pack voltage goes really low?

[@majdinj]

Another good battery is Samsung INR18650-30Q with 3000mAh and 30A continuous current draw

[@mibars]

There is a reason why power tool batteries have cells of such small capacities that go without protection circuits. They are simply much more robust and more difficult to explode than high capacity cells that push it to the limits and NEED protection circuits.

[@harleyme3163]

nothing to do with protection.. you know its only the voltage thats matter since they only draw the amperage that they require to function.. and if you think there's some special anti battery exploder.. most charging circiuts stop charging when its gets feedback (battery full and charge is coming back since battery isnt taking it.. you cannot overcharge a battery if you use a proper charger.. they are meant for specific amp bat's there for specific VOLTAGE..just takes longer to charge a bat with higher capacity

[@mibars]

@@harleyme3163 No! These Lithium cells are not self-balancing, like Nickel ones! You can have e.g. 6S1P battery with a total full charge voltage of 25,2V, but it doesn't mean that all cells will be 4.2V. It takes just one cell with slightly different internal resistance or lower capacity to throw the pack out of ballance, e.g. you will have five cells at 4.15V and one overcharged at 4.45V.

[@JM-yx1lm]

@@mibars ryobi does have individual cell charging.

[@mibars]

@@JM-yx1lm But the Bosch one from video doesn't.

[@Mr71chevyvan]

no 18650 battery can last one discharge cycle w/o a protection scheme. the protection refers to overcharge or draining below around 3vdc. i know because i ruined 2 cells w'o built in protection.

[@BlackCat-qm3sj]

Hey will this work with 12v cordless drill batteries I'm trying to use 2 12v drill batteries to make 24v would that work on a drill to make it faster and last longer?

[@ivang752]

I’ve ordered those batteries from for mention retailer and there are only 2000 mA not 3000 mA, I’ve checked capacity by discharging and fully charging again.

[@johnrhodes3350]

What voltage did you run them down to. Sony are probably going to 2.8V -> 3.0V at a slowish discharge rate. it might say on the spec sheet. There are some fakes around though. Have a look at the KZbin channel 'Battery Mooch'

[@ibysplumbingvideos9684]

Wouldn't this damage the battery circuits.

I have a 2ah battery on my drill, if i want to upgrade it, change the cells, do i have to change the circuit board or something? Or only to replace cells with better one?

[@jimpann]

Excellent job. Very clever idea.

[@VitorMadeira]

Outstanding. Just three questions: How will the old battery charger do with the new type of batteries? Is it 100% compatible? What about overcharging? I heard that it might be really dangerous to overcharge lithium batteries.

[@moya9450]

Yeah, Those are 18650 batteries and Their Voltage is the same, only capacity has changed, so older charger takes double time to fully charge it. About overcharging I have to say that I think that circuit board will protect the battery from Over Charge and Discharge

[@DIRTDIVER882]

Awesome craftsmanship 👍👍👍👍🇺🇸

[@niallwildwoode7373]

Some advice: NEVER dismantle fairly modern tool batteries with a long, steel blade. A small accidental short so easily wrecks the management system, rendering repairs and upgrades useless. I use a Dremel-type drill with mini steel cutting disc, and cut through all the connection strips in situ....then I can remove the strips off the individual batteries in safety, so as they can be used in less demanding appliances.

[@andypag1071]

Love your videos.Thanks for sharing. Quick question: Is soldering NiCads and Lithium batteries ok if you don't have a spot welder? Does it damage the cells?

[@Rendus4]

Soldering the cells does physical damage to the cells, but the general concensus is that the cells do not lose capacity or life cycles as long as the soldering heat was only applied for a few seconds, so be sure to use a 200 watt+ soldering iron and not the typical 30 or 60 watt ones.

You will have about 4000000 Amps though with a million batterys... Seriously doubt the motor can handle that...

[@ehvlullo]

@@sjaakvkoten6061 Nonsense, amps are always limited by the device itself. Putting cells parallel only makes for longer battery running times. Harley is right.

[@ЦыряСоломонович]

Hi! Is it possible to double capacity of Hilti cordless powertool like drill 22v 3.3Ah?

[@pr0xZen]

Maybe. Check inside, how its assembled and what cells are in it, ot will tell you whether there's really any gains to be had, and if it's feasible to do the job (this battery pack was frankly on the easy end of the scale to replace cells in, among modern power tool battery packs). But top shelf power tool manufacturers like Hilti rarely skimp on cell quality. Maximum capacity ain't everything though. Besides that and cost, ere's (sustained) discharge current, behavior in really cold or warm temperatures, long term capacity retention, lifetime charge cycles ratings etc. Can't have the best of everything in one cell, it's always a compromise. Some tool "system" manufacturers even offer special battery packs tuned for special needs, like arctic or super hot surroundings, and ofc the more typical high-demand (high discharge current) ones for super torque'y tools like hole hawgs, big impact wrenches, sawzalls, concrete hammers etc.

[@adamshandyhands2346]

Just one more thing, it is an 18v tool but when you checked your batteries on your volt meter they read bellow that, won't that effect the power of the tool?

[@kimt6333]

A fully charged 18V Li-Ion battery is at 21V, and a fully discharged battery is at 15V, so any voltage between that is good, it's a matter of charge state.

[@johnrhodes3350]

The reading was as they are shipped or for long term storage roughly between 3.4V to 3.8V Long Storage at Full capacity can damage them and is unnecessarily dangerous, due to high energy density. It's a risk of fire or explosion if short circuited or otherwise damaged He was only looking to see if they were all roughly the same ie. Balanced If one was lower than the others it could indicate a faulty cell.

Neat! Not only double capacity and hugely increased discharge current (useful for really torque'y tools), bit you get the compact form factor of the small'ish 3Ah one 😁 Top stuff. Any tips on "regular" soldering on these cells, without them letting the firely dragons inside them out?

[@socrateresorts1963]

Be carefull doing that, most rescent battery modules have a chip counting the numbers of charges and trouble. If the charger refuses it, changing battery inside the module wont do anything sadly.

Sony VTC 6 is the best li-ion battery so far. Larger energy holding capacity and a lot more output power, compare to its competitions. There are few brands has the similar capacity, output etc. but almost twice as expensive. li-ion batteries should become more powerful, more capacity, more life and cheaper. Not less capacity and more expensive, as those recently know Yellow and Black and the shiny purple battery brands do. I am sure you know these brands.

[@this_time_imperfect]

@6:48 I actually laughed out loud at this lol nice one!

[@psdaengr911]

A seven minute video to explain that replacing the cells 1:1 with ones having twice the cell capacity gives you twice the battery capacity? It also doubles the charging time and may overstress the charger because of the difference in max input current.

[@AntKardano]

It wont, Bosch uses an universal Charger for their batteries, which means that if you buy an OEM 6Ah battery from Bosch, you get the same charger that he has and it's designed to charge 6Ah batteries.

[@adamshandyhands2346]

Nice way to build a bigger ah battery, but as others have said, they have chips in them now to prevent over charging the battery. They can only be charged a number of times and my Makita batteries talk to my drills to prevent overheating and very low power in battery that it won't charge. You will also lose your warranty on any of your tools that you use that battery on. If that battery was to cause a fault in any of your drills then you wouldn't be able to claim any warranty.

[@adamshandyhands2346]

No, but if my pillows and mattresses are faulty I can claim a repair or exchange as they have the manufactures stiched logo/name on them. If not (like a pillow case) which some have a stiched tag on them which I leave on, I would usually find a fault within a few uses. But with this battery it looks very dodgy to any manufacture and they will want to test the batteries and drill that became faulty. They will want to check the battery used in the drill when it stopped worki g or became faulty. If they find that you used a non genuine battery then you will have no manufactures warranty at all and will be paying a premium to have your drill repaired.

[@adamshandyhands2346]

halojump123 It's the manufactures logo that is on every genuine battery and with this one anyone will be able to tell it is a fake. Plus what about the weight, wouldn't want to be using this battery for a full charge in one go or even for a full day where overhead drilling is needed, it would be easier on your arms and body to use a lighter battery and change it if needed. Also, how would OHS like you using this battery on site or even just to see it on site would be a problem. They would need to see all documentation regarding extensive testing and safety.

[@Brettj77]

They already do a 6 amp, so the weight wouldn’t be any different, I use it on my cordless rattle gun all day, if you can’t handle the weight, maybe hit the gym. Any site I’ve ever worked on couldn’t give a shit with stuff like that, and it’s not like he’s done anything dodgy, he’s done exactly the same as the manufacturer, exactly! Do you hear a collective sigh when you enter any area when people are talking?
