Maybe. More likely, and more in keeping with the theme, *OmniEvilCorp* introduces the tool and as time goes on the grade of components gets cheaper and cheaper.
I bought one of the 2.5 Hercules batteries to rebuild a toast Ridgid 1.3 ah. When I pulled it apart I was impressed to see Samsung cells. I ditched the Hercules circuit board and soldered the Ridgid circuit board on. Accidentally shorted out the fuel gauge when I was trying to measure voltage. I have already built a Frankenbattery out of 2 Ridgid 4.0s so the Hercules battery build earned the name Francules.
Drill- Packedge in typical box, came with a tool bag (added bonus), two batteries, one charger, drill, and driver. Two words "plenty of Torque" ruclips.net/user/postUgkxW1vOBRCMrgTCDEijzpVzDWsgI-Jm2iQv well I guess that's three. Nice upgrade from current setup. Has belt clips, I don't think I will be using those. Driver and drill were bigger than what I expected but it is an upgrade from the current setup. For the money I would say that this is a great setup for Professionals and DIY/Weekend warriors.
They were actually designed by the same guys. A few of the guys that designed for dewalt left and came to work for harbor freight to design stuff for them so that's why they are so similar.
a couple of good old zip ties or electrical tape will fix that engagement issue lol. I appreciate the time you put into this though thinking about grabbing one of the 5.0 ah ones and trying it . I will probably do a comparison of my dewalt reciprocating saw and the future harbor freight one. If I can pull two 5.3's in 2 hours at a junkyard im saving close to 400 bucks either way with two reciprocating saws.
You’re the only sharing these numbers and findings. Do you have a Bauer battery and does the therm read 100k ohms on the therm/B- connection also?? Thank you
This was helpful in the aspect that what you did I work in electronics and was familiar with it anyway. But 99% of people will not go through that much trouble. Cuz they simply don't understand. But there are a few companies or a company out there that are selling a adapters where you can interchange DeWalt to Milwaukee drills and batteries. Do a little research if you have some time and find out if those adapters would work for the Harbor Freight setup haunted DeWalt Milwaukee Etc.
Excellent video thank you so much. I took the battery apart and put the resistor in works great on DeWalt tool, but now it will not work in my Hercules tool. Is that normal? I was hoping to use the Hercules battery it in both tools.
You could instead of a resistor solder in the same type of thermistor used on the DeWalt battery, so that the DeWalt tools would get the correct reading but also retain your thermal protection on the Hercules batteries. maybe even put in a double pole swith that would allow you to switch between DeWalt and Hercules modes!
@@yonodc5705 The battery originally had thermal protection (to prevent damage from the battery overheating). In the video he used a resistor to trick the tool into thinking the battery is at room temp (because the temperature detection for the other brand doesn't produce the same resistance values the tool would interpret those reading as either being too hot or too cold and not allow the tool to operate [a safety feature]). This guy is suggesting adding in a compatible thermistor; which will actually change it's resistance based on temperature (so that you can regain the thermal protection for the battery). He suggested putting in a switch so that with the flic of a switch you can add or remove that thermistor from the circuit; doing this would allow you to switch from being compatible with either Dewalt or Hercules.
@@bradkaral1188 I don't sorry (been a year); without having a battery to check maybe you can find it in a forum discussion via googling. Good luck sir. Btw I'm a newbie myself; most complicated thing I've done electrically was a lichtenberg machine with two transformers and fans that run on either circuit (just took my time). Also made a nichrome wire cutter (studied things for a while). My friend is a genius with this stuff the guy has nearly rebuilt an industrial CNC from the ground up. Compared to him I'm a cave man clacking rocks together.
I don't know where you are but in Florida the DeWalt batteries go for 80 or $90 where the Hercules batteries all right around 45-50 so definitely a cool video I will be trying this next time I need batteries I may even remove the cells from the Hercules and install them into the DeWalt case
So for a Hercules tool, we would need to trick the tool into sensing 100k ohms across the temp sense wire. In theory, we could modify a bauer battery or dewalt battery to work in the hercules tools.? Is that right?
Dude Nooooice! Once you said Thermal, I was Floored, Maybe I should retireded! Of course that's what it is. I got a "20v Flex" dewalt Danger Grinder (with anti flesh destruction Brake) and today tried to make a corded Adapter but didn't bother to check resistance ( well besides my coworkers talkn crap on why would someone want that!) on the 2 inboard pins, just volts. I hope this is what I need but either way Thanks a bunch for the info.
To be honest when I saw the title of it i just assumed it was him, I remembered ave had I talked about it some in a previous vijayo. Was somewhat disappointed when I started watching and found out it wasn't. Oh well good info either way.
I absolutely agree, the Hercules battery pack as far as cell construction and the aluminum heat sink seems much better engineer than the DeWalt cousin. If I was going to do all this work I would definitely swap the harbor freight cells and assembly into the DeWalt case and then go down the road. I would definitely keep using the DeWalt BMS as it has everything in there to communicate with the tools for the protection of the tools and the battery.
Do you know how to make the hercules tools work with dewalt batteries the reason is I have alot of dewalt 20 volt batteries and wanted to buy just the Hercules tools
I just posted a video of a Milwaukee tool being powered by a dewalt battery with an adapter i made my question is how would i get battery protection like over current and undercurrent as well as overheating. I made a 3d cad file for a more compact adapter then the one i showed in the video and i would like to make it available for anyone to download to 3d print. The only reason I'm holding off is because there's no protection. I don't know anything about circuit boards but would it be possible to build a simple circuit board for battery (and tool) protection?
No surprise since there's a good chance that the person who designed the HF battery also did the DeWalt since the rumor is that both are made in the same factory in China.
How can you put a dewalt battery on a Hercules tool? My Hercules tool & battery, after pulling the trigger for a few seconds shut down & starts to flash. The battery test light stopped working, so I am assuming it is the temp wire causing the issue. The pin next to B+ & B-, I get 99.1k ohms.
great video! learned some good stuff here. question... i have the dewalt 20v toolset and i bought some hercules 20v bare tools. can i get the dewalt batteries to work in the hercules tools and dewalt tools[aside from the case modification], the way you did with the herc battery? thanks for your time
@@creepyunclephil unfortunately i couldn’t get it to work. i tried resistors and potentiometers and nothing worked. gave up since. if you figure it out, please let me know. best of luck to you
What manyt folks do not know is that apart from Makita and Hitachi the vast majority of power tools are made in the Black and Decker/Dewalt factory so it is not surprising that the fits are common.
Using a 10k resistor fools the tool into working, but it also bypasses the batteries' temperature protection. This is not a good idea as you could potentially have an exploding battery scenario. A better method would be to use a 10k thermistor across the terminals. You'd have to measure the Dewalt thermistor's resistance at different temperatures and compare to determine it's Resistance/Temperature curve to select the proper thermistor. You'd also probably need to isolate the temperature sense lead from anything else on the circuit board that might interfere with the thermistor reading as well. Don't know if you'd be able to charge the pack with 10k of resistance either as the Hercules charger would think the battery is really hot. The Dewalt charger probably won't work as it won't sense the cell balancing voltages.
Agree with the presenter. I have enough DW battery inventory for my needs and they are long lasting and rugged. I have never needed to replace one in several years of using the 20 volt max. If/when I need to add or replace I can’t imagine I would need to save a few dollars by using a slightly cheaper battery, then adapt it and still have a less than perfect system. Just buy a genuine DW. If it cost $10 more and works for say 5 years then $2 / year is well worth it. I would consider replacing a dead cell or two before doing this.
So if all he is doing is adding a 10k Ohm resister between the temp and ground, wouldn’t it be possible to make an adapter that you can slide the Hercules battery into and then have to top able to slide into the dewalt tool?? Would this be possible with 3D printing? That way you don’t have to do any messing around with the actual batteries and you can still easily use the Hercules battery for Hercules tools or dewalt tools
Yupp I work for Horrible Freight Tools and I seen the new tools come in and I seen the Batteries and was damn near shipping my self becaue the batteries and tools are damn near identical!
I read somewhere that HF hired some former DeWalt designers to design the new Hercules tools, so perhaps the same is true for the batteries, if any of it is true, that is.
so trying to understand here. Is the resistor you put in parallel to the thermistor on the pack? or did you just put a resistor with same load in same place as the dewalt?
I just put a resistor. If you wanted to mantain thermal protection, you could put a thermistor of the right spec. The harbor freight battery has a NTC style, and the DeWalt has a PTC, so you couldn't just add a resistor.
DeWalt just came out with a battery pack using lipo cells. I can't wait till they start bursting into flames. After multiple emails and inquiries I've yet to have a good explanation as to how they keep the lipo cells from turning into little explosion makers. In a cell phone the current demands aren't so great but in a power tool absolutely you could draw enough discharge current quickly enough to just absolutely destroy a lipo especially if afterwards you put it in a rapid charger. Imagine what would happen if you drop that battery with a full charge. You have an instant light show with some bonus smoke.
I just got a hercules battery for 10 dollars in the open box section. Im going to try this. My main concern will be charging it. I am probably going to charge wiyh a power supply on a current limit and s3e if that works. I'll figure out how to make the dewalt charger charge this later.
Great video. I've always used DeWalt batteries because I don't have any problems with them and they last for a long time. My question to you is: Where do you find DeWalt batteries for $30? I'll take a dozen!
Dangerous mod. That battery can overheat and explode. You should have bought a proper 10k thermistor with extension leads and soldered it on instead of that 10k resistor. It would work safely on either drill brand at that point.
There are adapters out there for sale that will let you use the 20 volt lithium ion batteries in place of the 18 volt nicad batteries. They might be nickel metal hydride. I think the nickel metal hydrate batteries are a little bit tougher and have longer life span, but the only on batteries definitely take the cake for fast charge and recharge ability. They take a beating in the service they're being used in and it's amazing they last as long as they do. I have four nickel metal hydrate batteries in a test instrument that have been in there and still working good after 15 years.
I wouldn’t buy a Herc battery, mess it up and hope all is well when I can buy a DW battery for a few more bucks and be sure it is fine and all warranties good. I would do a cell replace before this. Or buy a clone as long as it is just drilling etc. how often do you need to buy a battery? Those extra few dollars for the real article are spread over years. This was technically interesting for sure but confirmed to me to not bother trying it.
The 20 volt Black and Decker battery packs plug right in to DeWalt 20 volt tools. Are you saying the Porter Cable batteries and tools are interchangable as well?
Very cool. Thanks for hacking that!

Can you charge it in a dewalt charger now? Can you use it in Hercules tools yet?
do you charge it with Hercules charger or DeWalt charger?
Once you've seen one screw taken out you've pretty much got the idea.
Wouldn't the 10KOhm resistor be connected in parallel to the 100Kohm? so does that mean that dewalt needs an equivalent of ~9Kohms?
What needs to be done, if anything, to electronics for the hack in the opposite direction, running HF tools on Dewalt batteries?
I'm with you on that y no awnser yet boss what u got to do too run DeWalt in a Hercules
Could you put the battery from the HF pack into the dewalt so you dont have to cut up the case
Black Box I wanna know also
Ah shucks, the things that get churned out of the factories when 3rd shift punches the clock at those fine DeWilt chinesium facilities.
Does Bauer have battery protection in the pack or in the tool?
Can you do it with a Milwaukee?
If you're going to go through all that hastle, especially modifying the casing, why not should rebuild your existing DeWalt battery.
right? or just move the cells to from the HB to the dewalt.

Buy broken dewalt batteries on ebay, then fix them. I buy dewalt 20V batteries for 10 to 12$ each all the time in lots of 3 or more.
The reason I’m watching this video is 12 amp Hercules batteries are 80$ on eBay….
Making a power bank out of them
Ya but $30 for a 2.5Ah battery vs a 1.5 or i have even seen 1.3 but all the new ones will probably be 1.5 or 2
Kinda weird sanyo doesnt get a good rep for having that great of batteries in the 18650 circles
Hf battery are some times 15 bucks
what determines the size of the resister in this hack? If possibly a rigid battery can be adapted to dewalt would the same resistor work?
Harbor freight is unique in the temp design, as long as you can get a battery from Rigid to fit or an adapter you don’t need to maps off the internals
I love watching screws get takin out i always forget how

Why can’t you Just take the harbor freight batteries put them in the Dewalt case and swap the computer boards
I have a duet charger when I put the battery on it the red light is flashing how do I fix that
Sorry that was a DeWalt change
Need to see how close a Porter Cable is to Dewalt, since they are owned by the same company.

Just so you know. Once Stanley brought Porta Cable . They took the entire Black and Decker Firestorm line and remanded it as Porta Cable.
The 20 volt Black and Decker battery packs plug right in to DeWalt 20 volt tools. Are you saying the Porter Cable batteries and tools are interchangable as well?
