LiFePO4 vs NMC power stations: what the chemistry changes, on one maker's own numbers

Goal Zero sells a 1 kWh Yeti in each chemistry. The NMC one is rated for 500 cycles and the LiFePO4 one for 4,000, to the same 80% end point at the same 25°C, which makes the NMC unit about 6 times dearer per kWh it is rated to deliver, for 3.6 lb less to carry.

On Goal Zero's own pages, read 23 October 2026, its NMC Yeti 1000 Core is rated for 500 cycles to 80% and its LiFePO4 NEW Yeti 1000 for 4,000, so at 20 October prices the NMC unit costs $1.83 per rated lifetime kWh against $0.30.

Both cycle ratings to 80% of capacity at 25°C, on the makers' own product pages. Across the 32 power stations we track, 25 listings name LiFePO4, 1 names NMC and 6 name no chemistry.

Is LiFePO4 better than NMC for a power station?

For a unit that stays home and cycles often, on the makers' own ratings, yes:

  1. Cycle life: 4,000 against 500 cycles to 80% on Goal Zero's matched pair, eight times as many.
  2. Cost per lifetime kWh: $0.30 against $1.83, though the LiFePO4 unit costs $300 more up front.
  3. Weight: NMC wins, 31.0 Wh per lb against 28.3.
  4. Warranty: 5 years on the LiFePO4 unit, 2 on the NMC unit.

What does the chemistry change on one maker's matched pair?

Nearly everything except the size. Goal Zero's Yeti 1000 Core names "Li-ion NMC" cells and 500 cycles to 80% at a 1C discharge and 25°C. Its NEW Yeti 1000 names LiFePO4 and 4,000 cycles to 80% at 25°C. Both hold about 1 kWh; the LiFePO4 unit weighs 3.6 lb more and carries a 5-year warranty against 2. Because one maker wrote both ratings to the same end point and temperature, this pair compares chemistry rather than marketing.

Rated lifetime energy of Goal Zero's two 1 kWh Yetis, capacity times rated cycles to 80%, read 23 October 2026. NEW Yeti 1000 (LiFePO4): 3,994 kWh kWh. Yeti 1000 Core (NMC): 492 kWh kWhNEW Yeti 1000 (LiFePO4)3,994 kWhYeti 1000 Core (NMC)492 kWh
Same maker, same size class, the same 80% end point and 25°C test temperature on both pages. 998 Wh x 4,000 cycles against 983 Wh x 500 cycles: the LiFePO4 unit is rated for about 8 times the energy over its life.

How do you compare batteries on cost?

Per kWh the battery is rated to deliver, not per kWh it holds. Multiply capacity by the rated cycles to get a lifetime ceiling, then divide the price by it. On that measure the NMC Yeti costs $1.83 per lifetime kWh and the LiFePO4 Yeti $0.30, about 6 times less, although its sticker is higher.

What a battery costs per kWh it is rated to deliverGoal Zero NEW Yeti 1000, LiFePO4, 20 October 2026 price
How to turn a cycle rating into a cost per lifetime kWh: 998 Wh (rated capacity), then x 4,000 cycles (to 80% capacity), then 3,994 kWh (rated lifetime ceiling), then $0.30 per kWh ($1,199.95 / lifetime)998 Whrated capacityx 4,000 cyclesto 80% capacity3,994 kWhrated lifetime ceiling$0.30 per kWh$1,199.95 / lifetime
A ceiling, not a forecast: capacity fades from 100% toward 80% over those cycles, and a rating measured at 25°C says nothing about a hot garage. It is still the fairest way to compare two price tags, because it uses only the maker's own numbers.
Compare two batteries on their own numbers
1. Find the cycle rating AND its end point
   ("to 80%" or "to 70%"; a lower end point means more cycles).
2. Rated lifetime kWh = capacity (Wh) x cycles / 1,000.
3. Cost per lifetime kWh = price / rated lifetime kWh.
4. Check the test conditions: 25°C and a stated charge rate
   are the honest version; no conditions means no comparison.
5. Weight per Wh: NMC is lighter (Goal Zero: 31.0 vs
   28.3 Wh per lb), which matters only if you carry it.
6. Check the warranty: 2 years on the NMC Yeti, 5 on the LiFePO4.

What chemistry do power station listings name?

Mostly LiFePO4, when they name one. Of the 32 power stations in our disclosure index, 25 listings name LiFePO4 (LFP), 1 names NMC and 6 name no chemistry at all, including EcoFlow's DELTA 3 Plus, whose 383-character listing names neither chemistry nor cycles. The cheapest rated lifetime energy we found is the Jackery HomePower 3600 Plus at $0.08 per kWh, with the Pecron F3000LFP close behind at $0.08. Cycle ratings are where the comparison gets slippery: Jackery's Explorer 1500 Ultra counts to 70% of capacity, Goal Zero and Pecron count to 80%, Anker's SOLIX F3800 Plus page says "LFP, 3,000+ cycles" with no end point at all (read 23 October 2026), and most listings state no test temperature.

Price divided by capacity times rated cycles, from each listing's own figures. The highlighted bar is the only NMC unit. Only 5 of the 23 cycle ratings state both the temperature and the charge rate behind them, so the ratings are not measured to one standard.

When does NMC still make sense?

When weight matters more than cycles. NMC packs more energy per pound: 31.0 Wh per lb on the Yeti 1000 Core against 28.3 on the LiFePO4 Yeti, about 10% more. A unit that rides in a pack or a kayak and sees a few dozen cycles a year will not reach either rating; a unit that backs up a home or runs a cabin every night will. Goal Zero's own page also limits the NMC unit to 32 to 104°F in use, while the LiFePO4 page allows discharging down to -4°F.

Which chemistry should you buy?

How this comparison was made

Method

The matched pair was read on Goal Zero's rendered product pages on 23 October 2026, quoting each figure. Prices come from Goal Zero's own store in the Lattice price index snapshot of 20 October 2026. Rated lifetime energy multiplies rated capacity by rated cycles to the stated end point; it is a ceiling that ignores capacity fade, and it compares only what makers publish. The register view uses the cycle ratings in each listing's text (20 October). We did not cycle-test any battery, and we make no claim about fire safety beyond what the listings state; whether a listing names a safety standard such as UL 2743 is in our disclosure index.

FAQ

Is LiFePO4 better than NMC for a power station?

For cycle life and cost over time, on the makers' own ratings: Goal Zero rates its LiFePO4 NEW Yeti 1000 for 4,000 cycles to 80% and its NMC Yeti 1000 Core for 500. NMC is lighter, about 31.0 Wh per lb against 28.3.

How many cycles does an NMC power station last?

Goal Zero rates its NMC Yeti 1000 Core for 500 cycles to 80% of capacity at a 1C discharge and 25°C, read on its product page on 23 October 2026.

Why are LiFePO4 power stations heavier?

LiFePO4 cells store less energy per pound. On Goal Zero's 1 kWh pair, the LiFePO4 unit weighs 35.3 lb for 998.4 Wh and the NMC unit 31.68 lb for 983 Wh.

How do I compare power station cycle ratings?

Check the end point (to 80% or to 70% of capacity), the test temperature and the charge rate. Then multiply capacity by cycles for the rated lifetime energy and divide the price by it. Ratings with no stated conditions cannot be compared fairly.

What chemistry do most power stations use?

Of the 32 power stations we track from EcoFlow, Jackery, Goal Zero and Pecron, 25 listings name LiFePO4, 1 names NMC and 6 name no chemistry.

Bottom line

On one maker's matched pair, LiFePO4 is rated for eight times the cycles and costs about 6 times less per lifetime kWh; NMC is about 10% lighter per watt-hour. Buy LiFePO4 for anything that cycles often, and compare any two units on price per rated lifetime kWh.
