Aldi's new Ferrex range of cordless power tools have 2 battery options - a 20V lithium-ion battery and a 20V/40V battery. So how does the power tool get the right voltage?

    How does one buy theses tools? I ordered and paid for 2 tools but Aldi emailed me that I would not be having them and they were being returned to the warehouse. they refunded me the cost but no explanation why.

    40v is now 26.99.

    Why oh why are power tool batteries not universal? You can put money on the fact that when this battery comes to the end of its effective life, they will have changed the fitting. This also applies to the major brands, not just supermarket cheapies. One of the reasons I stick to 240 volt.

    hello Julian I have a problem with the Ferrex angle grinder after about 20 seconds it stops, do you have an idea what could be the cause? greetings JD

    hi how do i wire up a normal 2 wire terminal battery to those drill pins instead of using five pin battery

    Does the 40 volt last a lot longer than the 20 volt battery

    You get what you pay for, and seems ideal for occasional use.

    Do them active batteries fit the 18v ferrex nail gun? Or just the 18v ferrex battery

    I bought a "Pretul" brand 20V rotomartillo (hammer drill) here in Mexico with that same ID line. I'm afraid mine might actually use the ID sense line to prevent the tool from working with 3rd-party battery packs, but I'll know for sure in a few days when I get it to my workshop. My plan is to run it directly off my solar panel.

    I bought this drill from Aldi 4 years ago when it was branded as "Workzone" its done really well and still going strong. Back then they were selling this with 2 18V 2.AH batteries but this drill is my go to battery power drill driver. I would definitely buy another if it broke down on me.

    hmm great, tks, so, due to the lack of 40v batts, i might end up buying two 20v and modding them to provide the b1+b2 to the 40v torque drill i bought in discount. A 3dprinting wizard could come up with an adapter for two batts… 🙂

    Still worth to buy this battery just for use cells only to recondition old OEM battery. I just did my old makita LXT with cells comes from Parkiside However I can see now this has better cells – Its LG.

    Just bought the drill for £20, thought it was a good bargain. Took it out of box, no charger or battery, oh, sold seperstle £30 for battery and then £15 for charger!!!!! So it's going back as that will be £65. If it seems too good to be true then it usually is. Very disappointed.
