Nicely done. The drill and angle grinder are going to draw close to 30amps under heavy loading. To ease the load on the power supply you should also be running at 21 volts. That's what a fully charged 5 cell in series 18650 pack is at(4.2 volts x 5). Also the 3rd pin is a thermistor temperature sensor and generally it just needs the same voltage on the Positive terminal connected to it.
Thx very much for your comment man! You're the first to clear out the mystic 3rd pin, i thought so, that makes sense👍 And yes I never really had a look at the Amps while under full load, I'll check that out, btw sorry for the bad audio, that was one of my first videos... best regards from switzerland
@@suicideris 21volts isn't theoretical. I've measured this on many battery packs. 18650 lithium cells are charged to 4.2 volts each adding up to 21 volts for the pack of 5 cells in series. The tool then shuts off power when the battery is drained to 15 volts or 3 volts per 18650 cell. The nominal or mean operating voltage is 18 volts.
Thanks for the video. There were several issues that commenters have already noted. But I have been wondering if this was possible due to all the monitoring electronics in the battery pack. This video shows that it still is possible to hack a cordless 18V Makita tool into a corded tool. I wish tool companies would just come out with a cordless to corded adapter. But alas, business plans rely on consumables such as batteries, inkjet cartridges, and so on. However, there might be a "gray" market opportunity to sell conversion battery kits. I suspect that the unique but similar mechanical batter locking geometries are protected proprietary IP for each manufacturer, but a combination of reverse-engineering, ingenuity or "gray" market manufacturing could bypass that. Especially for DIYer's with a 3D printer.
Hi, First of all makita battery charger cut off at 20V so you should put that voltage too and you can even set 21V Secod thing is that tools take more current in heavy load so this usage on iddle what you show is just for spinning... this tools can draw much more amps when you use them to work and that is why battery and tool is overheating. I use makita around 5 years now everyday and they can easly draw 10 times this current what you show on idle...
This would be a fun way of really testing the tools limits… maximum overclock! I’d like to get one of these and overvolt them to 24, maybe 28V and see how they do. Having that live view of the current draw is also very useful. Could be a good way of properly comparing tools, as opposed to all the comparison tests which use roughly equivalent batteries from different brands which isn’t a good way to standardise a test. Only thing I’d do differently really is use a 1200-1500VA power supply, as some cordless tools today claim to reach these power levels

Why are you not use a 8k2 resistor between negative and NTC pins on drill side? Then you can run the drill. Because it probably use 10k thermistor, for secure battery from overheat. You can check the resistance on battery between negative and the extra (NTC) pin. Chose the same resistance resistor. And you have to use a bigger power supply.
Thank you so much! This opens up a lot of possibilities for me! Great video by the way.. not a lot of useless information very informative. Thanks again and take care ✌🏻😎 cheers from Brooklyn, New York USA 🍻
@@swissdadmakes3367 I think it would be enough if your cable is short, something like 1.6 meters. If you would run 3 meters, then cable should be 2.5mm2. I did mine 20V - 5 meters and 35mm2 cable and it still gets warm while working on heavy load. Just be careful ;)
@@suicideris thx again man, ive got around 5m with 1.5mm2, ive actually never touched the wires under full load, excellent idea man i will check if and how warm it gets, your comment is much appreciated👍have a good one
1.5mm2 ist enough cause ist seems that the power supply only delivers 10amps. You could see that when the angle grinder starts, it is limited at 10amps at startup therefore it took a long time to run at full speed. It would be interesting to see the tools under load, im pretty sure they suck then.
The angle grinder needs 5.5A? Maybe on idle. If you cut into metal or concrete this will probably spike to 30A, no? Then your little benchtop power supply will not be enough. I would love to know or see what happens if you run the angle grinder under load.
Hi, lovely video and some great work. TH-cam find of the week for me. I bought a cordless drill 15.6v with no charger and the battery pack had 11, 1.2v 1500mah batteries Ni-Cd. 3 of the 11 batteries had zero voltage, the rest ranged from 0.2 to 1.1v. I want to convert the cordless drill to corded. Please I have an old laptop adaptor with output rated as 20v and 3.25A, would this be enough to run the drill, or what would be the ideal range of adaptor to use? Kindest regards.
Hi there, thx for your comment👍 I cant tell you for sure but the 36v is just equal to two 18v batteries in series, then you just need to make sure that your ac to dc converter can deliver enough amperes, good luck and maybe you let us know your result👌
You can do it with one 40V 30amp power supply, but this option involves completely different wiring approach. Or you could use two identical 20V 30amp power supplies. Then you could make two separate adapters, and connect them to your machine. But keep in mind that two power supplies has to be identically the same, the same brand, same parameters, build in in the same way, otherwise you can get into some trouble. I would recommend first option, it's cheaper, safer, but you should know basics of electricity if you would like to do it from scratch.
Anybody knows the 3rd terminal protocol? Is it for temperature monitoring? Can we make it and pretend the 3rd terminal is present, without the battery board?
Is it possible to have it going out to two batteries outputting 18v to each using just the one ac to dc machine or would I have to buy a second one, I’m attempting to purchase the makita portable microwave and kettle and those items require 2 batteries to operate and I would like to connect to an outlet of sorts like you’ve done until I have enough to buy the batteries, if you can let me know or see if you can find out if it’s not too much trouble. Thank in advance, have a nice day
Your set up just won't provide enough ampage for demanding tasks. The original battery can output theoretical ampage of 40A. Just take a look at the spike ampage your driver draws without a load. It is as high as 9.46A . What spike ampage do you think it will draw under load? You'll either overload your power supply or under power your device.
great job .... would you do with plan for 110 v for 18 v 3.o am makita? i am ready to buy the plan also cause i m very FXXXd up with battery and charge them ... best regards
Hi there, thx for your question, well, I can't tell you for sure, but in theory it should work the same way for many of the battery tools out there, just try it out👍 best regards
I tried with the same battery, but with a 24v 6A power adapter and it only turns on for a brief second. I tested it with a meter and it shows the same output as the battery. Why doesn’t it work?
Hi there, i guess you already checked on polarity, i cant really help you, mine works fine on different machines, keep on trying and stay safe, best regards
There are a few things going on here. You can see in the video at around 8:25 when he boosts the Voltage the Amperage used goes up too. I suspect at 24V that 6A might not be enough. ALSO a lot of the switching power supplies have short circuit protection. Which basically cut the power after a brief second of drawing more amperage then it expects. If you care about the tool you probably want to lower the voltage to 20 or 21V and get a power supply that can do 10A at least. You can see from other comments if you're cutting/drilling into something especially tough people expect the amperage to jump even higher to 30A. I've yet to get this to work beyond a "proof of concept" (and then I blew a fuse) so I'm kind of trying to work out similar issues.
Hello, nice video! I have a question. You say at the end of the video that you bought a converter on Amazon. But you had not enough with1.2Ah for using it. Is it possible to do that but with a converter of 3Ah or more as exemple? Could you than get enough power or is it dangerous? Thanks man!
