I rarely see a 12V cordless hammer drill like this. This is my first experience with this tool, after open this tool I am really surprised with gearbox inside this drill. The drill is small but the structure inside is like the big one. The motor inside is like the motorbike starter motor. It consumes much current. If I can upgrade it to the brushless motor, that will be awesome.
Battery Rebuild Items
- BMS 3S40A
- Lithium 18650 3.7V 3200mAh
- Nikel strip
- 18650 Battery Bracket
- 12.6V 5A Li-ion charger
I hope you find something useful & enjoy this video!
I am happy to receive your feedback, advice, suggestions to improve myself.
!!! I apologize for the mistake if I have made in this restoration !!!
**I still keep some parts, I want to save the world's environment**

@Chrome-ws6qw 4 года назад

Just putting my thoughts out there regarding the circlip bending out of shape, when you heat the bare metal parts you are ruining the heat treatment of them! so the hardened keys that keep the gears locked to the shaft are likely now soft etc along with the circlip, hence why is bent out of shape so easily. For components which aren't hardened the heating and dropping in oil technique is perfect but for hardened components you should definitely look into getting some cold blue liquid since that will not affect the heat treatment of the steel! other than that awesome job! :D

Obviously you paralleled the 6 cells doing three plus three lithium batteries to get 12+ volts out of 6 cells. But that also doubled the current capacity as well... Thumbs Up!

This hammer drill must be OLD! Those are NiCad (Nickel/Cadmium) batteries. They used to place the 10th battery in the "neck" of the battery pack that goes up into the tool body. That is why it is there! Also, that is why he needed to make a "dummy cell", to mount the contacts to. :-) (1.2V nominal per cell, NiCad, in series X 10 = 12V. New battery pack is 3 X 3.7V cells in series (11.1V X 2 in parallel). The run time of this tool, when new, was a lot less than what it will be now with the Lithium power pack. Awesome restoration! It was in pretty rough shape!

Dear very good video, I would like to know how I can charge a 20 volt lithium battery from a drill that I don't have the original charger, I was thinking of using the notebook charger (19 volt), but it brings 3 cables so I don't know how to connect it to the battery which has 4 connectors I hope you can help me thank you very much and a big hug.

@gear_show 4 года назад

A drill 20V, the battery fully charged is 21V with lithium battery. Your lithium battery pack should has BMS to protect overcharge, low voltage cut off, and battery charge balancing control. You can use 5S BMS. 19V notebook charger provide out put voltage around 20V~24V. Use multimeter to find the right cable voltage. You can charge this battery in case the BMS have overcharge cut off featue. Please read BMS technical detail before the process.

@6lr6ak6 4 года назад

Good video and rebuild, heating the springs and bits then dropping in oil is that to colour or harden? Also this build must have cost a fair bit as the new battery cells aren't cheap?
