Our take on the BLACK+DECKER 20V MAX 2 Speed String Trimmer/Edger LST522

The LST522 is a cordless 20V string trimmer that converts to a wheeled edger, with two speeds and a 12-inch cut. It ships with a 2.5 Ah battery and charger, so it runs out of the box. The two-speed switch lets you cut at full power or drop to low speed for longer runtime while edging. It suits small to mid-size yards and light trimming around fences and beds; heavier overgrowth and large lots call for a bigger cordless trimmer or a gas unit. Owners like the light weight and the automatic feed spool, but some find the 12-inch swath narrow and the edging conversion fiddly.

Questions and answers

Is the LST522 good for edging driveways and walkways?
Yes, it converts to a wheeled edger with the head rotated 90 degrees. The low speed setting gives longer runtime for edging. It is slower to set up than a dedicated edger.
How long does the battery last?
Expect roughly 20 to 30 minutes of trimming on high speed and longer on low, depending on grass thickness. The 2.5 Ah pack is small, so a spare battery helps on bigger yards.
Does it come with a battery and charger?
Yes, one 20V MAX 2.5 Ah battery and a charger are included. The battery also fits other BLACK+DECKER 20V MAX tools.
How does it compare with the LST300 or other 20V trimmers?
The LST522 adds a second speed setting and a larger 2.5 Ah battery over the base single-speed models. It keeps the same 12-inch cut and automatic feed.
What line size does it use?
It uses 0.065-inch round trimmer line on an automatic feed spool. Replacement spools are widely sold.
Is it good for large yards or thick brush?
No. The 12-inch cut and 20V motor suit small to mid-size lawns and light trimming. Dense brush and big lots need a more powerful trimmer.
