beyond by BLACK+DECKER 20V MAX String Trimmer / Edger, 12-Inch (LST522E1AEV)

What It Is

This is the complete BLACK+DECKER LST522E1AEV 20V MAX 12-inch string trimmer/edger unit (tool only, no battery or charger). It’s designed for light-to-medium trimming and edging around lawns, flower beds, and walkways.

Fitment & Compatibility

• Battery system: Requires any BLACK+DECKER 20V MAX battery (LBXR series or older 20V slide-packs). Does NOT work with 18V NiCad or 40V MAX batteries.
• Charger: Use any BLACK+DECKER 20V MAX charger (e.g., LCS20, BDC2A).
• Cutting width: 12-inch swath – check if your yard size and trimming needs fit this smaller path. Avoid for heavy weeds or large properties.
• OEM direct: This is the factory model, not an aftermarket knockoff. No adapter needed.
• Edger feature: Flip the head 90° to edge; works on standard concrete/asphalt curbs but not deep soil.

Key Things to Know

• Battery not included: Factor $40–$60 for a battery and charger if you don’t have one. Total cost often exceeds $150.
• Installation difficulty: Tool comes mostly assembled – attach the guard, spool, and handle. Takes 5 minutes.
• Auto-feed head: Line advances automatically when you tap the head on the ground. Some users report jamming with thick line; use 0.065-inch line for best results.
• Power: 20V is suitable for light grass/weeds. For thick brush or extended use, consider a 40V model.
• Warranty: 2-year limited – covers defects, not wear items like line or guard.

Should You Buy It

Buy this if you have a small to medium lawn, already own a BLACK+DECKER 20V battery, and want a lightweight, easy-to-use trimmer that also edges. Skip it if you need more power for heavy weeds, don’t want to buy a separate battery, or prefer a gas model for larger yards.
