- Please share your experience with us, if you know the correct answer. I do appreciate for all the answers.
The Original Battery 15.6v 3Ah
- Normal voltage is 15.6v = 13 cells x 1.2v
- Fully charged voltage is 19.5v = 13 cells x 1.5v
- Capacity 3Ah or 3000mAh
- 13 Nimh cells 1.2v 3Ah or 3000mAh
Lithium-ion battery 18v
- Normal voltage is 18.5v = 5 cells x 3.7v
- Fully charged voltage is 21v = 5 cells x 4.2v
- Capacity is 3Ah or 3000mAh
- 5 li-ion 18650 LG 3000mAh 20A
Lithium-ion battery 14.4v
- Normal voltage is 14.8v = 4 cells x 3.7v
- Fully charged voltage is 16.8v = 4 cells x 4.2v
- Capacity is 6Ah or 6000mAh
- 8 li-ion 18650 LG 3000mAh 20A
The motor can accept 19.5 volts. I think 18v or 5s is the best choice for this project, but the battery case can only load 5 cells so the capacity is only 3Ah. If the motor works well with a 14.4v battery, it will be good because the 14.4v capacity is 6Ah. I decided to build both types for testing. As a result, the drill with 14.4v battery performed well with the test. I think 14.4v is my best choice for this tool.
I hope you find this video useful and enjoy!
I am happy to receive feedback, suggestions to improve myself.

Thank you!
I would be afraid that too much energy would burn down the motor. Since it's not happening I think I would use 14V for everyday work and I would keep 18V battery loaded for special use or for some other impact tool. Great work!
Great point, thank for sharing!
Got the same situation. I have a cordless drill with two different battery packs. 3S and 4S lithium. One additional cell doesn't matter at all.
Do not speak, let the tools speak only with their own voice 🌟
Great job Sir.
I personally would run it with the 18v setup you showed.... It looked to me like it had better rpm's and better torque....
It'll also be lighter.... Which, if you have to walk around with it some, that will be a plus....
Okay, thank you so much for sharing :)
18 volt more power but low runtime!
14,4 volt good power and runtime is better configuration.
Yes, thank you for sharing :)
Man those old DeWalt impact drivers he used at beginning are some of the longest lasting impact drivers ever, and the old DeWalt Nicad drills from the early 2000’s.
Oh, it's 20 years old.
Yep I hope it works well for you.

congratulations friend great job
Thank you :)
once made an old rusty hilti 15,6 run on the bosch 18v system. no probs so far. just using full batteries and all, so probably 20v-ish. but results ofcourse may vary ;)
Nice job man keep up the good work.You're the boss!!!!!

i thinh when you need powe use 18v, when you need more work time use 14,4v
Yes, you're right :)
Nice job :-) yet again! cheers, Ruud (NL)
Thanks again!
The extra capacity (and potential for more current delivery) here is going to benefit you more than an extra few volts and half the current delivery capacity.
Yes, thank you for sharing :)
Beautiful
Excellent work👍👍👍 . Thanks for sharing
Thank you! Cheers!
Amazing presentation and super install 👍

Really good work
Whether it is 18v or 14.4v it is important to have a bms while you charging the battery pack. As drills are highly power consumpting , charging and discharging cycles may very short so you have to charge once a day(may differ).how ever li ion batteries are more dangerous than nimh batteries so you must have a bms. But the issue with having a bms inside a drill is whenever we use to drill something ,onset of drilling: requires a non-rotating stage. In this stage drill motor act as a ohmic resistor, So you know that copper winding inside drill has very low resistance ,so ultimately current goes high as #hit. So BMS definitely cutoff its power and drill goes off. Every time you try to drill something ,this happens. So it's better to measure current draw before setting a battery pack.
The answer to your question ,according to my knowledge , is to use upper voltage as the voltage go high power of the drill goes high. This is true only if you dont use a BMS inside the drill. So you have to connect battery directly to the drill. But whenever you charging it's better to use a BMS . Unless single cell may die very soon because capacity of each cell is not equal . The cell which has lowest capacity will charge soon as well as discharge soon. This will lead to over-discharge and over-charge of that particular cell.
Think this may help you in some manner.😊
Okay, I do appreciate with your information.
@_Schwalbe_262_ A capacitor won't be effective as a soft starter because if we try to start drill with a load, current drain will exceed the maximum current limit of BMS and it gets off.
best option to get maximum power of drill while using a BMS is , use BMS to charge cells, but not to supply drill motor. So power line to drill should directly come from battery terminals.
By this way we can have the maximum power of drill but keep in mind over discharge protection is not available in this method
@_Schwalbe_262_ images.app.goo.gl/dN2VDThbf45wCdaH7
here the schematic. The idea was to bypass the bms and supply directly to motor from battery.
@@thilinaakalanka5678 Your advice leads to a risk of damaging the cells by overdicharging or worse - fire hazard in case of motor failure. You should never use li ion batteries without BMS.
Your BMS may activate due to high starting current, but most of them can be modded to increase the delay of overcurrent protection by soldering a different capacitor to a specific pin.
Thanks 👍👍
عمل رائع شكرا لك اخي
Good job thanks
My head tells me 14.4v, but my heart wants 18v
I have the same thought before I make this project.
👍👍👍👍👍
I have a very similar project in mind. But planning on changing the base of the tool to accept makita batteries that way i dont need an extra charger or need to repack cells and bms. But im unsure if the 15.6v motobo drill will take the higher voltage. Any ideas???
Good job 👏
Show, congratulations
yes
1:00 this way always work 😁😁😁
Yes, you're right :)
It depends on the motor nomimal voltage. If the motor is 15-20V then you can use 5s configuration. If you don't have the motor's data then it's better to go with 4s configuration, in high current loads you might even have better performance than 18V because of less voltage drop and more power from the battery pack! Moreover, if the motor is not capable withstanding 18V in the long run you are diminishing motor's life span.
Okay, thank you very much for sharing :)
❤Aamezing dude❤
Glad you like it
Hmm, i would prefer 18V on this one since it's also drill.
Thank you for sharing!
good chop
Amazing video 🙏 :)
Glad you liked it!
Thank you for sharing
My pleasure
using 4s 6AH battery is reasonable in this project. The performance of the machine does not decrease much compared to the battery 5s 3AH
Thank you for sharing :)
Well done
Thank you!
How do you know if you need more or thicker nickel strips? Do you know how many amperes does the motor draw?
After long time waiting
Yes,
Wow
Good job mash'Allah
Thank you!
Amazing good video infomation brother 👍
Many many thanks
Geniales como siempre 👍¿Podría mandarme enlace de donde compras esas baterías de litio?
Awesome
Thank you!
Awesome sir
Thank you!
Thank you
Welcome!
Good job sir, I like it
Thank you!
Amazing..
Thank you!
15,6/1,2 (nimh battery voltage) = 13 cells. Nimh batteries can be charged to 1,4 volts so 13*1,4= 18,2 volts. I would say use 18v li ion ;)
Okay, thank you for sharing :D
Спасибо за видео!!!
Да, с удовольствием
Excellent sir ❤️❤️
Thanks a lot
I’m thinking of way’s to retro fit my grandfather’s makita tool. It’s a 14volt but one of the first 14volt’s the machine just feels so nice in the hand but it’s not powerful enough I’m trying to source materials to covert it to 2021 18 volt standards
Всё классно как всегда!
Thank you!
Great video good brother
Many many thanks
The packing foam may act like an air filter under the batter lid air vents
you need more fresh repair like loss tension on selector... from cordless drill. because I have some hahahhahaha.... always nice dude... go ahead...🙋🙋
Thanks for the tips!

Have you ever tried retro bright on the stained grey parts before? I think it would really improve the look of your tools.
Yes, thank you for the idea.
Hi is there any way except battery cells welder device for assembling? Can you show us?
Nice
Thanks
Enough room for 5 of 26650 5Ah batteries?
How do you make stickers
I make them with Adobe Photoshop and print with Canon inkjet printer.
u should check the motor rating as the durabilty of rhe windings wire is affected by generated current from the applied voltage, choose the longer life voltage
Okay, thank you for the tips.
is that clear tub you used to watch the shell an old record player dust cover?
Yes, it is :)
18v for the win. Wouldn’t use any other voltage.
Okay, thank you!
Hallo TH-camer, ich hätte eine Frage, wo bekommt man die kleinen Zahnräder her

Very good job, but my friend why you are used Li Io changer why you are not use the normal charger because already you have protection board for Li Io battery.
The protection board designed to work well with li-ion charger.
I noticed that in drilling test you anticlockwise rotated to hole.... Was it intentional?
It is an optical illusion caused by the speed of rotation of the drill and the cameras shutter speed
Is it possible to build a 15.6v 5Ah battery for this power tool, or is it too big for the battery case?
Also, the capacity of each battery is as follows: 14.4v/6Ah = 86.4 W/hr, 18v/3Ah = 54 W/hr.
Great tips, thank you for sharing :)
I wonder how do you print all these labels. What kind of printer and what software do you use?
I use Adobe Photoshop and Canon Inkjet printer.
if u need torque or speed go for 18V but if u need low power for small screws or simply more run time go for 14.4V
Yes, thank you for sharing :)
nicely done. the price of these batteries is 2 or 3 times higher than that drill, is it worth doing something like that?
Thank you!

All manufactures should not be able to sell there products such as power tools etc etc unless they make spare parts for them as these days you are lucky to even get a replacement part, SICK of this throw away society. I was raised to repair something if it broke.

Hi, great video! Can you recommend the seller/brand of the 18650 cells, or is it a local seller? Thank you!
Hi, thank you! I bought these batteries from China 1688 dot com. detail.1688.com/offer/550188755852.html

@@gear_show unfortunately 1688 dot com doesn't seem to sell to Spain. Nevertheless thank you for your help! Keep those great video restorations coming!!
Снял одну половину показывает другую.....
Dear GearShow! 18V stronger. :) My opinion.
did the same but extended the box and went 2x4 batteries, the way you did it it's not gonna last more than 15 min.
Okay, thanks for the idea.

The 2nd way to remove drill chuck are commonly works because of kinetic energy I guess
Yes, you're right :)
i thijnk that is a national model drill?
你也太酷了吧你看他們 我查查看你的影片 他會修東西了
Greetings!
I'm watching from Russia.
I still didn't understand why this test was needed at the end with different voltage batteries?
It seemed to me that it works the same way?
It isn't the same, 18V is more power that 14.4V, But 14.4v lasts longer than 18V.
6:14 The power was cut off. I didn't warm the water. :D
Tốt
it is possible to change the motor from brush to brushless
Yes, it is great idea.
