Both the 20V and the 20V/40V battery dismantled to check the cell specs:
20V battery has LG HD2 cells - 2Ah capacity, 25A max continuous discharge, 4A fast charge.
20V/40V battery has LG HE4 cells - 2.5Ah capacity, 20A continuous discharge, 4A fast charge.

Hi Julian, did you ever get round to posting a video for the charger teardown? Thanks
hi great videos can you please tell me as i would like to use the batterys i have the 20/40 v batterys and would lke to use them camping or fishing and would like to power lights and items as you can buy a unit that is a usb charger that allows you to charge phones and such as i have low watt led lights which use a usb fitting what compaitble usb units do i buy to use with thease batterys i.e makita .. dewalt .
Why are they saying that the batteries are 20V and 40V? Aren't the Li-ion 3.7V?
Would these batteries fit Dewalt?
Did you ever teardown the charger? I bought one looking for a cheap 21V CC/CV psu to replace one that had blown on another piece of equipment. The ID input is a problem though. I opened it myself to see and it's complex, controlled by a ST MCU which monitors the output current, battery temperature NTC and feeds back to the power stage to control the voltage. I don't know what it does with the ID, it could be a basic analog thing or perhaps a digital one. I will need an oscilloscope to see. Did you work out the ID?
Nice video
👍
I’ve got one of these 20/40v batteries but no charger , anyway to charge it with a adjustable dc power supply or maybe a charger for a different brand drill ?
these tools are amazing, but aldi has stopped selling the actual batteries just one year after production. wich makes them all useless……
Since this video I have looked in a 20v battery pack, from last year and now it has more circuitry, and this week I have another on order due 3rd April 22
Let’s see if more circuitry has been added again
What voltage are we expecting on the T pin?I have connected the ferrex air pump to a power supply set to 20V, the Led comes up briefly but the pump doesnt start, making me think that the microcontroller thinks the battery has a low voltage. I dont have this issue with the impact driver as it doesnt seems to make use of the T pin. I currently dont own the battery asa I use the Lidl one. anyhelp help much appreciated. thanks
Hello ! Why does my comment/question I posted yesterday on nov the first twentytwentyone disappear from your subject ? Tchotto. Thks
Does anybody still have this battery? I'm trying to make adaptor for lawn mower, but it does not work when i give ~80% from battery voltage to temp clamp. Tool is 40v, and author while stripped down tested it only with 20V battery pack. My question is:
Does it have up to 20V on temp clamp when connected to 40V tool, or is it doubled, because cells are joined in serial, so it's gonna be up to 40V on temp clamp?
Cool, now i know what is inside these batteries, thanks for sharing 🙂
Really impressed with that drill… I bought one of those a year ago, £30 battery (20/40) and a charger and I’ve brutalised it all year… still going strong. It was so good that I bought the rotary SDS and the impact driver. For the three drills and two 20/40 batteries I paid £130! All with 3 year warranties. You really can’t complain at that; even a cheaper brand you’d struggle to get that set for much shy of 4-500 quid.
did you manage to hack the charger? I would like to charge other batteries. unfortunately I can't cheat the ID slot.
