Li-ion 18v or Li-ion 14.4v Should I Build for Nimh 15.6v Power Tool? 

He is the type of man who does not throw away old tools👍👏

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!

ты молодец! даёшь вторую жизнь старому инструменту.

Nice job man keep up the good work.You're the boss!!!!!

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.

18 volt more power but low runtime! 14,4 volt good power and runtime is better configuration.

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....

congratulations friend great job

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 ;)

Do not speak, let the tools speak only with their own voice 🌟

Nice job :-) yet again! cheers, Ruud (NL)

Excellent work👍👍👍 . Thanks for sharing

You should run it a "reasonable" amount of time with both packs, and measure how hot the speed controller is getting. Remember to also check at less than full RPM. It is probable that this is the part you would wear out, unless your tasks often put the drill in a near stall state, then with the motor bogged down the 18V will be worse because it's not pulling air through it. Ultimately I have faced a similar situation and I chose neither. I would have chosen a 14.4V, 4S1P pack with only 4 cells, because like you, I have multiple drills and when I need high power I will reach for one of my newer more powerful drills, with newer cells in their battery packs as well, so for rebuilding an old drill that already has significant wear anyway, to not push it too hard and make the battery pack retrofit worthless because the drill dies, I would use the drill more for light duty, with ligher weight battery and cutting the # of cells I used would be more important, so it would just be a 4 cell pack and what I'd often end up using one for, is have a 1/4" adapter in it for screw driving, so I have one more powerful drill making the drilled holes then that drill driving the screws, and in that case, since your holes are pre-drilled, the torque isn't needing to be much, and higher RPM just makes modulating the lower RPM you want, require more attention and care. However, for lighter weight, that isn't the right drill to choose no matter how little the battery pack weighs. Unless you have other tools that can use the same battery pack, I would question whether it is worth rebuilding a pack for it at all, let alone two packs at different voltages so you need two separate chargers and with one, not even being a regular dock since you need the two separate PSUs so something has to get swapped around to charge both packs, making it less convenient and subject to user error if you aren't paying attention. Likewise having just those battery connectors with wire soldered on, wouldn't cut it for me. I'd want it plug and play for any random soul that comes along and thinks that they know how to charge a tool battery without realizing what you've done. :) Plus if your dodgy generic chargers fail and cook the batteries, 4 cells makes a smaller fire than 5 or 8 cells. ;) We could hope that the BMS saves the cells, but to some extent those BMS are only designed to work with a properly functioning charger and could fry themselves if the charger starts getting wonky. Another thing that can fry the BMS is the back EMF from a brushed DC motor, often the BMS have instructions to put a capacitor and/or diode(s) across the power leads to mitigate that. It does make you stop and think, if the BMS fails, will the result just be a dead drill, or worse.

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.

Thanks 👍👍 عمل رائع شكرا لك اخي

Interesting project and great job buddy👍👍👈

Beautiful

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.

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???

Really good work

i thinh when you need powe use 18v, when you need more work time use 14,4v

This is the best Editing and Restoration video on RU-vid 🤩🥳, i love it😍

Good job 👏

Amazing presentation and super install 👍

How do you know if you need more or thicker nickel strips? Do you know how many amperes does the motor draw?

Geniales como siempre 👍¿Podría mandarme enlace de donde compras esas baterías de litio?

Good job thanks

Show, congratulations

good chop

Hammer time!

The packing foam may act like an air filter under the batter lid air vents

After long time waiting

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

Lord of gear ⚙! 🌹

Well done

using 4s 6AH battery is reasonable in this project. The performance of the machine does not decrease much compared to the battery 5s 3AH

Amazing video 🙏 :)

Hmm, i would prefer 18V on this one since it's also drill.

Thank you for sharing

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.

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.😊

Good job sir, I like it

Nice

Awesome sir

Thank you

Good job mash'Allah

Amazing good video infomation brother 👍

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

Have you ever tried retro bright on the stained grey parts before? I think it would really improve the look of your tools.

Awesome

❤Aamezing dude❤

Great video good brother

Спасибо за видео!!!

Enough room for 5 of 26650 5Ah batteries?

Hi is there any way except battery cells welder device for assembling? Can you show us?

Amazing..

The 2nd way to remove drill chuck are commonly works because of kinetic energy I guess

Всё классно как всегда!

👌👍

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.

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 ;)

yes

My head tells me 14.4v, but my heart wants 18v

Có thể đóng được 10 cell 18650 vào vỏ National 15v6, thành 21v 5Ah, dùng mạch Makita màu vàng 5s65A. Vietnamese.

quá chuyên nghiệp

Excellent sir ❤️❤️

6:14 The power was cut off. I didn't warm the water. :D

👍👍👍👍👍

厲害！

18v for the win. Wouldn’t use any other voltage.

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

is that clear tub you used to watch the shell an old record player dust cover?

you need more fresh repair like loss tension on selector... from cordless drill. because I have some hahahhahaha.... always nice dude... go ahead...🙋🙋

1:00 this way always work 😁😁😁

Wow

Hi good day to you sir. I would like to ask regarding to my old tool, a SDS Hammer Drill with a Ni Mh 24V, is it possible to be converted to 24 V Lithium Ion battery? thank you sir

Hallo RU-vider, ich hätte eine Frage, wo bekommt man die kleinen Zahnräder her

I wonder how do you print all these labels. What kind of printer and what software do you use?

nicely done. the price of these batteries is 2 or 3 times higher than that drill, is it worth doing something like that?

آفرین

I noticed that in drilling test you anticlockwise rotated to hole.... Was it intentional?

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.

What type of motor is inside

Huge motor , over 20A 15V ?!

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

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.

Tốt

👍👍👍👍👍👍👍👍

it is possible to change the motor from brush to brushless

Hi friend good job . please I have drill with 14.4 v 1.3ah what is the chose ans number of the batrie lithiom thinks

Dear GearShow! 18V stronger. :) My opinion.

Love from Kerala ❤️

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?

Не дай бог получить шуруповерт после такого мастера

Hi, great video! Can you recommend the seller/brand of the 18650 cells, or is it a local seller? Thank you!
