Fantastic work, dude! 😃 Those kits are fantastic indeed! Stay safe there with your family! 🖖😊

Amazing work. Very instructive. Congratulations.

Thank you so much! It was beautiful and a pleasure to watch 🥳🥳🥳

Appreciate the Video as this will appeal to us DIY folks

thank you for sharing. This was a very interesting and informative video.

Excelente tutorial maestro , un trabajo impecable , gracias por compartir sus conocimientos , un saludo cordial y por supuesto un gran like desde Narón (Galicia) 🔝

VERY Well Done !!! thanks

I've just replaced in an cheap battery tool (HS) the cell with some with more Ah capacity, and it works well. Thank you for letting me know that diy battery kit exists

Nice work.

hey great work! can you maybe give us some info about where to get the DIY kit so that we can give it a try

thank you!!!

I also agree. I think Makita should make batteries that are like 9ah since they would last a long time and run their cells cooler. I think I will try and take on a project like this with the packs that I currently have when they go bad. Would you consider making a video on 21700 batteries in the future? Thank you for all the videos that you have made.

Hello, where can I buy a pack like I know? I already have the batteries but I can't find a pack like that with the motherboard

I've made a couple of these and I have a hard time getting them into the charger. Any ideas?

Probably waiting to release a 21700 version

I need to do this because I absolutely demolish 5.0 batteries because I have the 36v self propel mower, 36v power head with a tiller and string trimmer attachments, and leaf blower. I have 10 of the 5.0 batteries, and it's still barely enough, I have to throw my batteries straight onto the charger and I'd prefer to let them cool down to make them last longer.

can you make a bigger pack video for Makita BL1013 batteries?

Very good video, where can someone buy the setup u made? Tganks

makita also does a 18V LXT Lithium‑Ion Compact 2.0Ah Battery which takes 5 18650 cells which weights just 458grams. makita uses samsung INR 18650 2500mah batteries. so if you put 3500mah 18650 inside you can get 40% more battery time. and that's actually the power that double the size and weight batteries have. it's insane.

The voltage varies with charge on lithium batteries. These 5 cells in series packs are ~ 20 volts fully charged, 18 volts average voltage throughout their capacity, and ~ 16 volts fully discharged. Give or take a bit so that's where he got 21v from - brand new cells so he got a 1v bump for now. All lithium cells follow this with individual cells 4 v charged, 3.6 nominal, 3.2 v discharged. So when DeWalt says their packs are 20v max compared to other brands saying 18v (nominal) they are all the same packs. DeWalt just tries to fool the consumer by measuring their packs voltage right off the charger where everybody else measures the average voltage over the whole cycle. There is no difference. So yes you can use this on a 18v tool as the factory batteries follow the same voltage curve as these.

Why do people add music to videos that don't need music?

00:44 maybe makita don't like to abuse their power tools

can you sell 2 of this and how much ?

ok, but WHERE do you buy original cells? They're quite expensive

and where is the heat controller on the battery pack??

This 18650, is litokala ?

Clean I wonder if your used top quality cellls whatever the highest mah cells they make and build it how badly could you beat the oem battery in a 3 mah or 5

Although battery technology is incredible and has really advanced a lot in the last few decades... It isn't magic. It kind of has to obey the laws of physics... I'm not intimately familiar with their battery designs... But they may have legitimate reasons behind their design and choices of the individual cells. Capacity is important.... Arguably even more important are the discharge characteristics. Especially in such a powerful tool. It's very possible that sells they have chosen...Might not have the biggest capacity.... But were needed because of their high discharge rate and characteristics under stress And the cells with the biggest capacity wouldn't be capable of discharging as quickly or enduring the same amount of output power. A balance has to be struck. Because each end user is different and will have different patterns and habits in how they use the tools. For somebody drilling holes or tightening fasteners every few minutes... High discharge currents are more important. However, For someone only using it a few times a day... I could understand why high-capacity would be more valued. But they had to strike a balance.

I've searched what is available on the market and I confirm last answer. Generally speaking, the more capacity 18650 cells have, the less max current they get. Makita cells are samsung INR18650 25R (or 20R for lower capacity batteries). They provide 2.5Ah capacity and 22A max continuous current output (even more in spike). I assume you can't get lower max current if you want your tools to work properly. The biggest capacity available within 18650 shape with at least 22A max current is 3.12Ah. So you won't beat by much the oem ones (specialy considering the cost). The pros with 4s3p rather than 4s2p is that battery's current is 3 times the current of 1 cell (rather than twice). So you'll be able to buy cells with lower max current specs but with higher capacity (or just lower price). The cons is that it's big, heavy, and might be too much for some people. Also a fun fact is that it costs ~40€ for 4Ah and if you build it yourself it will cost the same price (without all the brand's support and guaranty). So there is noway you'll find better price/quality. Actually I've bought a chinese one labelled as 6Ah, and I've opened it... It was marked as 2Ah samsung cells. So it was actually the same as makita's 4Ah batteries but with a chinese label and... more expensive

replacing the 6V or 12V battery in kid toys, is gonna be interesting

What is the final cost of this 9,0 Ah battery? P. S. Makita has 6,0 Ah in its lineup.

Backpack battery holder PDC01 (i paid a bit over €400) and you have 24 Ah (room for 4 x 6 Ah in the device , there is space to carry extra batteries on the harness) and PDC1200 has 33,5 Ah , its pricy , round €1200 and takes long time to charge . Metabo did put out statement why they only have 2 rows of cell in their batteries ... middle row is only heating up the other cells ... Metabo has 10 Ah battery , with only 2 rows of cells ... if there just would be an adaptor to get Metabo batteries to Makita .

rather than 18650 x3 parallel, its not better using 26650 cell? more ah, more compact and less weight for sure

But the batteries are 3 e or more per battery 10 for post that’s 40 e before case and nickel

Wow

Unfortunately this build will not last very long. Batteries have to be top balanced and protected by a BMS that controls the voltage of each series cell. And a passive balancing would be good. This pcb don't protect each cell and does not balance. I did this some years ago not knowing how to really work with li ion and unfortunately i destroyed about 11 Sony vtc6 after about 20 cycles.

There are also a lot of restrictions on power density limits when transporting or shipping batteries. I know of multiple instances where companies had to choose a lower capacity or certain characteristics... So that they could ship pallets of batteries easier without going over the limits imposed by the shipping companies. Lithium ion batteries have been suspected for multiple airplane fires mid-flight... Uspostal and many other companies have hard limits on what is allowed.

​@@hullinstrumentsI don't have much to say other than no. They don't because they want folks using XGT. All that you've written is just rationalising for a company. They could and should offer higher capacity.

I bought that 9AH battery off Amazon and it only lasted a month

wait, the bms only know one string voltage? if yes this is fucking mad dangerous

Makita should also make 21700 battery packs. I got a couple of kits for them off Aliexpress. If I populated it with Molicel P45B cells, then I'll have a 9Ah 90 amp pack with just 10 cells.

Complete nonsense. I'll decide if a battery is too big (which it isn't). If you have a very intensive job then switching out/recharging battery's on a cycle is a nuisance. I don't get people like you, you're some kind of Makita fanboy. They don't make them so that people use XGT. Simple as that. Having larger capacity battery's makes perfect sense for consumers to have the option. It makes NO sense for you to justify for Makita why they should offer more options to consumers.
