EGO Peak Power: what running two batteries actually buys
Almost every cordless tool takes one pack. The handful that take two behave differently enough to change how you size a purchase.

We have not tested these units. Every spec on this page comes from the manufacturer's own documentation and is linked to it. Every computed figure is arithmetic you can redo. Prices are checked daily — last verified January 1, 1970. Here is exactly how we pick.
Nearly every cordless tool on this site runs one battery. A small number run two, and EGO gives that arrangement a name. It is worth understanding properly, because it changes both the energy arithmetic and the platform argument in ways a single-pack tool does not.
What Peak Power is
In our registry it appears on both EGO snow blowers, and nowhere else. That is not a coincidence: snow clearing is the highest-draw, least-interruptible job in the yard, and it is the one where stopping to swap a pack is least acceptable.
The energy, converted
Whatever the power claim means, the capacity is arithmetic. Two packs is two packs.
The tools that use it
| Tool | Packs | Energy | Published claim |
|---|---|---|---|
| EGO SNT2400 snow blower | Any two 56V; 2 x 7.5Ah recommended | 840Wh at the recommended packs | Up to an 18-car driveway with 8 in of snow |
| EGO SNT2134 snow blower | 2 x 56V 6.0Ah included | 672Wh | Up to a 14-car driveway with 8 in of snow |
| EGO LM2135SP mower (for contrast) | One 56V 7.5Ah | 420Wh | Up to 60 minutes |
| EGO Z6 zero turn (related idea) | Four 56V 10.0Ah, six bays | 2,240Wh installed, up to 3,360Wh | Up to 2 acres per charge |
From EGO's own product pages; the snow blower pages fetched 9 September 2026. Watt-hour figures are our arithmetic.
The Z6 is the same idea taken further: not two packs but four, with two spare bays. We work that through in riding mower battery bays.

Why "any two" is the load-bearing phrase
Compare the two snow blowers in our registry on this one point and the platform argument appears immediately.
| EGO Peak Power | Greenworks SN80L620 | |
|---|---|---|
| Packs used | Any two EGO 56V ARC Lithium | Two Greenworks 80V 5.0Ah, included |
| Packs shared with | Mower, blower, trimmer, chainsaw, hedge trimmer, pole saw, zero turn | Greenworks 80V tools only |
| If you already own the platform | The batteries are already bought | Only if you are on 80V specifically |
| Spare capacity | Any additional 56V packs you own or buy | Additional Greenworks 80V packs |
| Charger | Whatever 56V charger you already have | Dual-port rapid charger, included |
Greenworks runs 24V, 40V, 60V and 80V as separate non-interchangeable platforms, so "already on Greenworks" does not settle this — see the Greenworks platform guide.
A snow blower is used a handful of times a year and carries two of the largest packs in the range. If those packs are stranded eleven months of the year, that is a lot of capital sitting idle. If they are the same packs that run the mower all summer, it is not.

Sizing a Peak Power tool
Because the pack choice is yours, the coverage claim is not fixed — which is unusual and genuinely useful.
Note the 672Wh line lands at 14 car-spaces — which is exactly what EGO publishes for the SNT2134 on its two 6.0Ah packs. Two independent claims agreeing is weak evidence the rate is real. The full conversion is in the snow blower runtime guide.
What Peak Power does not do
- It does not publish a runtime. Neither EGO snow blower states minutes, only driveway coverage.
- It does not publish a charge time. Two packs to recharge and no stated rate for either machine, which is the sharpest gap in this category.
- It does not tell you about mixing capacities. EGO publishes that it takes any two 56V packs and gives no guidance on pairing different sizes. We will not invent any.
- It does not change cold-weather behavior. Nobody in this category publishes a cold derating, on the one tool guaranteed to be used below freezing.
- It does not make the tool lighter. Two packs is two packs of mass, on machines where EGO publishes no weight at all.
What it means for a platform decision
The general rule on this site is to choose a platform on the fourth tool rather than the first, because the mower is rarely the constraint. Peak Power is a concrete example of why: a snow blower is often the fourth or fifth purchase, and whether its two large packs are shared or stranded is decided years earlier.
The winter side of that decision is in which battery platform for winter, and the full EGO range is in the EGO 56V platform guide.

What we cannot tell you
EGO does not publish how the two packs are managed — whether they discharge simultaneously or in sequence, whether the tool balances them, or what happens with mismatched capacities. We do not claim any of it. We also cannot tell you what the "power" part of Peak Power delivers in measurable terms, because EGO publishes no torque, wattage or amperage figure for either snow blower.
What is arithmetically certain is the capacity: two packs, double the watt-hours, and a machine that draws from whatever 56V batteries you already own.

56V x 7.5Ah = 420Wh per pack; two packs = 840Wh. Over the published 18-car driveway at 8 in of snow that is about 46.7Wh per car-space. It is a work-per-charge figure rather than a runtime, which is the more useful shape for a job measured in driveways.
What the numbers favor
- Runs on the same 56V ARC Lithium packs as EGO's mower, blower, trimmer and chainsaw -- no new platform
- Peak Power accepts any two 56V packs, so existing batteries go straight in
- 20 in intake height and a 50 ft throw, the largest published figures here
- Independent brushless motors for auger and drive, published separately
- Four LED headlights, published
What they don't
- EGO publishes no weight for this machine at all
- The 18-car coverage claim is tied to the recommended 7.5Ah packs; smaller packs will do less and EGO does not say how much less
- No published ingress rating on this model, where EGO publishes IPX4 on its single-stage
your driveway is short and flat and the snow is usually under a few inches. A two-stage machine is a lot of hardware for a dusting, and the single-stage costs less energy per pass.

56V x 6.0Ah = 336Wh per pack; two packs = 672Wh. Over the published 14-car driveway at 8 in of snow that is about 48Wh per car-space -- within a few watt-hours of the two-stage EGO and the Greenworks, which is a useful cross-check on all three claims.
What the numbers favor
- Publishes an IPX4 weather rating, which the two-stage EGO does not
- Steel auger, published, rather than an unstated material
- 45 ft throw and a 200-degree chute on a single-stage machine
- Ships with two 6.0Ah packs that also run every other EGO 56V tool
What they don't
- 13 in clearing height against 20 in on the two-stage machines -- this is the spec that decides deep snow
- Single-stage augers contact the ground, so this is not a gravel-driveway machine
- EGO publishes no weight
you get deep or drifted snow, or your driveway is gravel. A 13 in clearing height and a ground-contact auger are both hard limits.

56V x 7.5Ah = 420Wh, using EGO's advertised pack voltage.
What the numbers favor
- 420Wh in the box -- the largest included pack of any flagship walk-behind on this page
- Eight cut-height positions from 1 to 4 in, the widest published range here
- Three interchangeable lower blades (mulching, high-lift bagging, extended runtime)
- 5-year tool warranty, the longest published on this page
What they don't
- EGO publishes torque (7.0 ft-lbs), not motor wattage, so it cannot be compared directly against Greenworks' 1500W figure
- The 7.5Ah pack that earns the runtime claim is also the expensive one to replace
your yard is under a quarter acre. You would be paying for 420Wh of headroom you will never discharge, and a 20 in push mower cuts the same grass.

#ad No verified live price right now, so we show none rather than a stale one. How we're funded.
2,240Wh of the same 56V packs that run the rest of your yard, and a published two acres on a charge.
Published specs
| Deck | 42 in |
|---|---|
| Power claim | 22 HP gas equivalent |
| Top speed | 8 MPH |
| Batteries included | 4 x 56V 10.0Ah |
| Bay capacity | Up to 6 packs |

Source: POWER+ 42" Z6 Zero Turn Riding Mower (ZT4204L), egopowerplus.com
56V x 10.0Ah = 560Wh per pack. Four packs = 2,240Wh; six bays filled = 3,360Wh. Against the published 2 acres on four packs, that is roughly 1,120Wh per acre -- the number to size any electric riding mower against.
What the numbers favor
- Uses the identical 56V ARC Lithium packs as EGO's handheld tools -- the batteries are not stranded
- Six battery bays, so range is a purchase decision rather than a fixed limit
- 5-year warranty covering tool, battery AND charger
- 32 published LED lights, which matters more than it sounds for dusk mowing
What they don't
- Four 10.0Ah packs is a substantial share of the purchase price on its own
- EGO's published watt-hour figure for this configuration does not reconcile with 56V x 10.0Ah x 4; we publish our own arithmetic (2,240Wh) and show the working rather than repeat a number we cannot verify
your lot is under an acre. A 21 in walk-behind finishes a half acre in the time it takes to get a zero turn out of the shed, and costs a fifth as much.
