Tinted cells mark the better figure on that row alone: more engine, longer bar, lighter, cheaper. A lighter weight is only a win on the same basis.

What owners like and complain about

Stihl MSA 300 C-O

  • 2.5 kW output Stihl itself compares to the gas MS 271 — real 50cc-class cutting
  • Oil-flow sensor catches dry-bar situations before they ruin a bar and chain
  • Three selectable power modes stretch runtime for limbing versus felling
  • Up to 44 minutes of cutting on the 9.4Ah AP 500 S pack
  • IPX4-rated, magnesium-housed, and built for daily commercial abuse
  • Runs .325 RS3 Pro chain — not a low-profile homeowner chain
  • A working kit (saw + AP 500 S + AL 500) runs about $1,555 — more than a gas MS 261 setup
  • Full-day commercial use realistically requires multiple $400+ batteries
  • 14.1 lbs with pack — no weight savings over the gas saws it replaces
  • 2-year battery-product warranty is short given the system investment
  • Dealer-only; no retailer review aggregate exists to sanity-check long-term reliability

Husqvarna 550i XP Kit

  • 4.3 hp and a 20-inch maximum bar — the only Husqvarna battery saw rated for 50cc-class work
  • Full-size .325/.050 C33 chain rather than narrow .043, so chain stock is cheap and everywhere
  • 79 ft/s chain speed matches the pro gas saws for cutting speed
  • Ships as a kit with a 9Ah 40-B330X and charger, so the quoted price is a working setup
  • BLi-X packs carry across Husqvarna's whole professional battery range
  • $1,310 against roughly $750 for the gas 550 XP Mark II — a $560 premium for the same class of cut
  • 8.82 lb bare is the heaviest saw in the battery range, around 2 lb over the 540i XP
  • Runtime on one 9Ah pack is the real constraint; a full day needs a second pack and more money
  • New enough that there is no owner-reported durability record to check
