If you take your time and love your tools, they will serve you well for a long time.
+ In this category you will appreciate not only the low price, but also the ergonomic design and the “bonuses” in the form of cases and additional accessories.

What is the difference between 18V and 20V Li-ion cordless tools?
None. It’s just a change of designation.
All 18V (20V) batteries (up to 2000mAh) are made up of 5 cells. Each charged cell has a voltage of approximately 3.6V under load and 4V without load. It follows that a charged 18V (20V) battery will have 18V under load and 20V without load. Previously, the EU specified the battery voltage at load, which is 18V, but now it is also possible to use 20V, which most manufacturers are moving to. This is the same for the other types of battery, 10.8V/12V and 14.4/16V or 16.6V, where these batteries are technically identical and differ only in the designation.
