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 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....
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 ;)
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.
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.
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.😊
@_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
@@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.
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.
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.

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???
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
you use the original 16.8 volta, it will be better for the machine! in Vietnam. This machine uses 16.8 Volta 5ah, the machine is stronger and more durable! Anyway, you did a great job!
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.
I reccomend using a battery that inconsist with motor Meaning if that the motor is 14.4v use a battery from the same voltage but with higher capacity If you want to use a 18v battery change the motor to 18v
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.
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
I built 14,4 v with lithium bataries . But my balanced BMS device broken in a short time. Now doesn,t work. Now ,l will build again. Which BMS device should l use for my drill ?
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

I reccomend using a battery that inconsist with motor
Meaning if that the motor is 14.4v use a battery from the same voltage but with higher capacity
If you want to use a 18v battery change the motor to 18v
Maybe use a LiFePo4 battery? 16v = 5 cells x 3.2v. Capacity will be little bit lower but lot more battery cycles and higher discharge rate.
Do you know motor dosent has exect rated voltage???
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.
