Perdón...buenas tardes, hace un tiempo yo hice lo mismo que usted, pero a la salida de la pila 18650 hacia el motor, en su terminal positivo (+) le puse en serie dos (2) diodos rectificadoras de 2 amperios cada uno, los cuales hacen caer 0,7 Volt cada uno aproximadamente, logrando bajar de 4,2 volt que es cuando esta cargada la celda 18650 a 3V. Es lo más parecido a la realidad original. Saludos y excelente video! 😉👍
pienso como ud, pero hay varios fallos #1 ese modulo antiguo no tiene protección de la batería como lo tienen las versiones mas modernas que tienen adicional la salida positiva y negativa independiente de la entrada de carga, y en vez de colocarle 2 diodos le colocaría otro modulo un step down y así le bajaría el voltaje exacto y preciso al original , además cambiar la fuente de alimentación ya que esa fuente es de muy bajo mah ese modulo trabaja con 1a , y con la respuesta que el da sobre el motor , hay que verificar bien cuanto voltaje dc como máximo soporta el motor, pero si lo que yo quiero es dejarlo como el original lo hago con los 2 módulos el tp 4056 con protección de batería y el modulo step down para dejarlo como el original y usando una fuente de alimentación de 5v 1a
I’ve found one in the “trash”. It’s B&D KC9024 similar to this. Someone has converted it to wire only mode. I tried it and works well, so after your video I was inspired to make this work again without a cable. I have now the battery and the charging circuit so all I have to do is make it done. Great video. Thanks.
Hi. I have a same tool model, B&D KC9024. I had a problem with circuit tp4056 . the circuit burn when connect an engine. The engine runs fine. Do you know the problem?. Thanks
Thanks for your video, I have the same screwdriver B&D 9018 2.4 V since about 20 years. I didn't use it for 12 years and when I was to use it again the battery failed, I bought some others that didn't work. Thanks to you now, I know how to fix it.
i've bought the same 9018 on flea market for 2 euros, without charger, fella thought it was useless, and from another fella i've got a broken vape for 1 euro. vape had 3.7 good li-mh battery inside, and i had nine eagles li-ion usb 5v->3.7v charger dongle, so, it all vent inside 9018 and it works great now ! 3€ invested and 30 mins of my time, but it was fun to get that thing do to its buzz again and i charge it now on usb male-femaile extension cable
Nice video! I have one same model since new, I think I bought it in 1999, I want a similar modification, but leaving the USB-C connector accessible from outside and maybe use strong magnets to keep the bottom of case together. Thanks!
@@DaftOldMan Hello my friend. Is it possible to use 18650 batteries?? Do you know what kind of batteries are the original? I am about putting knew batteries cause the old died...
Great Job but instead of cutting the black wire on the charging input side you should have removed the old one and connect the new one in it place, less joint to wary about. thank you for a great presentation
Excelente, tengo un B&D 9069, que no funciona, pero con ésto creo que podré revivirlo.¿con la batería de Li, no subirán mucho las RPM?, Gracias por el Video Tutorial.✌
You could have easily fit 2 of the 18650 batteries in this and had a much longer lasting tool. Also gotta change out the charger .. the nicad charger will destroy the lithium batteries.
It worked perfectly for me, it is connected as you told me. When it is connected right, does the module turn on a light when the battery is low or does the module automatically cut it off?
When you connect through the module the module will cut power at 2.5v. The modules work fine for bulbs and LED's but motors can cause the module to cut power every time high current is pulled. I just charge mine when ever the motor feels slower. 2 years of use now and the battery is still ok.
Hi. I have a tool model B&D KC9024. I had a problem with circuit tp4056 . the circuit burn when connect an engine. The Battery of littio charge fine. The engine runs fine. Do you know the problem?. Thanks
@@DaftOldMan Exactly, this motor is connected to the output of the module, I made the connection the same as in the video in the link that you gave me. thank you so much.
You don't need to do all this chip soldering, Just need to use a DC to DC Buck converter and set the out put to 4.2 volt and it will stop charging due to it reaching an equilibrium
I have a torch here that has a dc to dc buck convertor but it still uses a battery charge/ discharge protection board (BMS) so I guess the manufacturer does not think a buck converter on its own is good enough.
Nice job! Could you post a sketch or diagram drawn on paper or something like that, so I can see exactly how everything is connected? I have a screwdriver similar to yours and I would like to make that lock. Thank you !!
No. DC motors are not rated at one specific voltage. My dremel that I converted to a 12v motor runs on 30v DC with no problem at all. At higher voltage the motor may spin faster and wear out sooner.
@@DaftOldMan so all the old resistors and diodes were for the old charging,circut and now the battery is just connected directly to the motor with out any voltage regulation ? this is how I imagained it and was exactly what I hoped to find out on this video. Cheers mate good job.
@@aaaronmiller100 Yes the diode seems to be to stop the old batteries going flat if you left the screwdriver plugged into the charger with the charger turned off. This does not apply with the LiIo battery and infact the LiIo charger will not function correctly with the diode left in circuit.
Thanks for commenting. The charger is AC but the screwdriver has a diode to give terrible rectification to DC. I assume NiCd batteries were happy with this.
@@DaftOldMan lol, why use one diode when 4 would do the job properly. I was a Black & Decker service centre manager back in the early 90's, these drivers and the dust busters were the bane of our lives.
Hi, i have a question, how much current allows the TP4056 to let through before cuts out? I have a similar screwdriver B&D and i have the same idea but technical characteristics of a TP4056 writes that cuts-out at 3A and above. I measured the current of the motor in heavy load and is at least 6A with 4V....If you can pls answer to a fellow DIY...

No necesitas los diodos para bajar el voltaje. Al motor no le importa un ligero aumento de voltaje.

I do not use the bms for output, only for charging. 4 years later it still works perfectly.

Thank you, that is very funny. I don't know about courage, more like being daft.
Why do you need the control circuit for the lithium battery?
Lithium battery must have charge control to stop charge at 4.2V. Without charge control a lithium battery can catch fire.
You could have easily fit 2 of the 18650 batteries in this and had a much longer lasting tool. Also gotta change out the charger .. the nicad charger will destroy the lithium batteries.
Make a video showing how you fit two 18650's. I converted the charger to 4.5v dc which will charge a single 18650
Thank you
It worked perfectly for me, it is connected as you told me. When it is connected right, does the module turn on a light when the battery is low or does the module automatically cut it off?
When you connect through the module the module will cut power at 2.5v. The modules work fine for bulbs and LED's but motors can cause the module to cut power every time high current is pulled. I just charge mine when ever the motor feels slower. 2 years of use now and the battery is still ok.
@@DaftOldMan Perfectly.Thanks!.
Will the 3.7v battery not damage the motor made for 2.4v?
No. Motors are rarely made for one exact voltage so 3.7v just gives a faster speed so it may wear out quicker.
Dig your videos. As someone else said, "clear explanation". I like that your not endlessly running off at the mouth. LOL!

Doesn't this bypass the discharge protection on the tp405 module?
The board I used doesn't have discharge protection only charge protection.
You don't need to do all this chip soldering,
Just need to use a DC to DC Buck converter and set the out put to 4.2 volt and it will stop charging due to it reaching an equilibrium
