EGO 56V Arc Lithium Platform
The cordless platform that actually replaced petrol for UK gardens
The story of this engine
EGO launched the 56V Arc Lithium platform in 2014 and has driven cordless adoption in the UK ever since. The architecture peaks at 56V instead of the more common 36V or 40V, which lets EGO mowers genuinely match petrol on cut quality and runtime. Single-battery design (no per-tool battery hassle) shares with their hedge trimmer, leaf blower, chainsaw and pressure washer ranges. The platform pros now choose for residential landscaping in noise-restricted zones.
Why owners like it
- Genuine petrol-replacement performance on dry lawns up to 1500m²
- Arc-shape battery dissipates heat better than rectangular — faster charging without degradation
- Cross-tool sharing covers most garden power tools at a credible quality level
- Battery retains 80%+ of capacity after 5 years of weekly use
Where it falls short
- Premium pricing — EGO 56V mowers are typically £200 more than equivalent 40V Greenworks
- Battery replacement at year 8 is £150–£250 — factor into ownership cost
- Charger and battery only sold through authorised UK retailers
- Charging requires a 13A socket within reach — fast-charge draws 6A continuously

The cordless platform to buy if you are leaving petrol behind for good and want one battery system covering all your garden power tools. Worth the premium over Greenworks or Worx for the cross-tool ecosystem and the genuinely premium build quality across the EGO range. Skip if you only need a mower and have no other cordless tool needs.
