Aldi appear to have dropped their previous "Workzone" cordless tool range and replaced it with a new brand called "Ferrex". There's a drill, impact driver, angle grinder, multitool, also strimmer, hedge trimmer, lawnmower, and even a chainsaw. Most of the tools are sold "bare", and then batteries and chargers are sold separately. The li-ion batteries are "20v" at 2 AH ( i.e. what other manufacturers call 18v ), but also "20v/40v" at 2.5 or 5.0 AH in a self-switching series/parallel combination ( similar to the deWalt 18v/54v Flexvolt idea.) So one of these batteries would have 5 AH capacity at 20v in the drill, or 2.5 AH at 40v in the angle grinder or the chainsaw. Frankly, the tools look rather "plasticky" and flimsy to me, not even as rugged as the Lidl Parkside range, and they have not upgraded to brushless motors.
