Hi MVVblog Thank You very much! I am honest enough to admit when I have been a stupid F** ,, and it is usually rather entertaining. Thank you for watching! :-)
You could have soldered the dc plug to the circuit board input instead of using the usb. You could still solder the dc plug to the board and have to two ways to charge it.
@@MyPlayHouse I think Scott meant that you would wire the DC in jack to the Input +/- of the module (that's what those solder pads you didn't understand were for). The TP4056 linear charging IC used on those modules can tolerate up to 8V input, so wiring to the DC jack with the module likely would have let you use the original charger for the power tool, as it would have cut-off current at 4.2v for you regardless of DC input used (up to ~8V)
FOR YEARS i HAD A cordless screwdriver, battery failed so I soddered 2 wires to terminals and added connectors and simply had to put small 6 volt battery in my pocket to run it.
could not we just wire the batteries like the retail ones but have the charging pcb charge it externally through the socket that the normal adapter uses?
The original batteries are only 1,2volt each,, so they need to go in series to get up to 3,6Volt,, whereas the 18650 Li-ion cells are 3,6volt and therefor I put those to in parallel.
@@MyPlayHouse that fact prevents us from charging the batteries through the original socket ?(where we plugged the adapter before, we plug to the charging pcb's input)
@@MyPlayHouse I apparently forgot to like the video yesterday but I very much enjoyed it, especially the fact that you included your mistakes and most diy videos don't. My earlier comment was about your accent, it reminds me of Gru from "dispicable me" Great content, thank you!
Hi salem abuomar Thank You very much! But the problem is that if the voltages is just 200mV over 4,2volt,, bat things can be the result :-/ Thank you for watching! :-)
Unfortunately, that isn't what they are for. What you are talking about is the USB-PD spec, which those extra ICs do NOT do. The extra chips are a DW01 chip for over-discharge, over-charge, and over-current protection of the Lithium battery. The other extra chip is the FET controlled by the DW01 to switch on/off the load in the event of a fault condition mentioned above. The USB-C connector on there doesn't do anything special besides simply being a superior connector :)
If you are using 18650 cells 3700mah is max,, everything over that is Chinese wishful thinking :-) and you will be lucky to get 10-20% of what they promise. But you can put any 18650 cells in... and better batteries gives better performances.
Hi william Logan Thank You very much! I do not remember talking about horrible people,,, it's mostly just whiny bitches :-) Thank you for watching! :-)
This is really helpful and has reversed my decision to throw away my B&D HP9048 Type 1 which is still like new but flat as a pancake. It is a 4.8 volt screwdriver so as I'm no electrician could you advise what the best batteries and charging circuits I should use when I upgrade it? Ideally I would like to use a USB charger as you do. Thanks.
While buying one with a DW01 protection IC would have been better, It's unlikely the FET controlled by the DW01 would handle the large spike in current draw from the motor, and also the DW01 is likely configured to cut load at no more than an amp or two anyways.
@@nickldominator It's true. i tried today with protection circuit and it burns the board as soon as you press the power button. Led's won't turn on anymore. So i made the same as in the video. Only using battery terminals and hoping to charge it before battery is discharged too much.
There is no acid in lithium based batteries Even though there is no metallic lithium inside, water would cause lithium to catch fire. The electrolyte is alcohol based and most modern lithium batteries have no other substances in them just cathode material, anode material, separator and alcohol. Electrolyte is created with lithium and it does happen by itself.
Is it possible to power the screwdriver with one 18650 since it can supply 3.7v? I'm trying to do it with a tray / battery holder and new a 3d printed end cap.

What are the better websites to find replacement batteries for a decent price if I'm not going to buy a large quantity? Are there any alternative places one should be looking for batteries as well?
@@Felipe2077tv Where did I say it does that? I merely said that if the batteries are destroyed by overdischarging he has plenty of spares lying around.
Saludos tengo un screwdriver 3,6 volt. Cordless Craftman. Me podrías decir la capacidad de las baterías que debo sustituir y la cantidad de ellas. Y el cargador viejo que traía el screwdriver no se puede usar con estas nuevas baterías. No hablo mucho inglés si me puede ayudar seria excelente para recuperar mi screwdriver. Gracias

Smashing upgrade :-D I think people warn you about correct Li-ion charging because they don't want to see you hurt. And some like a good moan he he :-D
What a stupid comment! I am a million times more likely, to get internal brain bleeding, from slamming my head down my table, from this, brain dead comment. Then those 18650 to just catching on fire.
Arme un taldro destorniar pero ahora no lo supe almar y ahora no le sirve el rache dond le dan velocidades me puede ayudar por favor.para saber como.lo arma
Hola amigo tengo un problema con un taladro de esto blackan deke lo desarme pero no lo pude arnar solo el problema que tube es no me fumciona el lado dond estan los numero

it's two 18650 batteries connected in parallel? After the modification, can I still use the original charger to charge it directly? Is it safe to do so?
@@MyPlayHouse Awesome! Can I use the original charger to charge the 18650 battery? If not, could you show me how? I'm not really savvy with electronics.
Haha :) Once I made the same kind of mistake with hot glue in the USB conector. Charging board you used has no battery protection circuit. I will not prevent under charging or overloading for example. The other one you have got has this feature, hence extra chip and connectors on the USB type C one. Plus and Minus connectors beside USB socket can be used instead of USB, so you didn't really need to dremel out that hole. You could just drill a little hole to see your favourite blue LED. It was fun to watch, thanks :)
@@MyPlayHouse No, it will not become weak, but it is necessary from the battery protection circuit, because without it the battery will die and perhaps from the first use
I wonder why do they set up the battery like this? The battery set up is permanent and not easy to replace for ordinary people. Black and screwdriver just grounded and i had to dump it because i couldn’t replace its battery 🥲
Those Nickel batteries are wired in, and sometimes can be upgraded to Lithium, but I just put a small wire-leg resistor/cap/diode unit on it, and the SAME BATTERY lets it keep the charge…
I bought 2 of 14500 cells with BMS (to replace 3AA Nicd cells) and it doesn't work. What confused me is the model I have has a built-in flashlight and the flashlight works well D: But not the motor! I then use a multimeter to check what happens and the result blows my mind. IT WORKS! WITH THE 10A MODE CONNECTED! WTH!? uh... I have no idea how to use a cordless screwdriver with that multimeter's attached to it all the time...
Hello, in case you have the Black&Decker Screwdriver model KC4815, could you please provide the connections of the internal cables? Thanks a lot in advance.
Hi, I did the same and have same model Black and Decker but it didn't work. I lost 3 modules already. I have no idea what is the cause of the damage. I connected all wires by given instructions. Small chip heated up and stopped working and no blue light turned on again.
I have the LI2000 model with a dead battery. It has a single cell in it, and I'm not sure if there's anything different about it such that it would warrant a different kind of replacement.After taking it, there's no labeling on the paper around the cell to identify it. Thoughts?
Hi Paul Sieberth I would check the cell first,, if it is under charged,, it might stop working and the elektronikk might prevent it from working as long as it is under charged. Put a slow charge on the cell 100mA 4volt and see.. glad you liked the video :-) Thank you for watching! :-)
I have a old one of these I don’t no where I put it. I also have a old robot vacuum that has a ni-CD battery and it’s battery died😡 love this video and are you doing something for movember like the moustache 🤗
Hi MOWER FACTS Thank You very much! I have a Irobot video comming where I find a NI-CA battery,, and Don't mess with it, just replaced it. No I am not doing movember,, sorry. Thank you for watching! :-)
great, i have this one, will try this. i also have some realy old non workable 20v conrad screwdriver, which i would like to fresh it up with li-ons or something. some tutorial on something like that?

I have 2 newer versions of Black & Decker electric screwdrivers, that are already on LI Ion and a Bosch ixo 4 electric screwdriver an older version, one of the first versions with LI Ion power supply, and they are super ok for activities that require low speed and torque .
@@MyPlayHouse Well, I also don't use mine often either, in fact, I use them quite rarely, from time to time when I have something to do that requires their special talent :), otherwise, I use various drills drivers but depends on the situation.
@@MyPlayHouse yes, my cousin Omar he used to make battery bombs, he lost his job in a work-related accident, it was at that point when he discovered that ISIS health insurance does not cover dental 😝😝😝
