LiFePO4 vs NMC batteries in power stations
Checked: 2026-10-25.
Power stations use one of two lithium-ion chemistries: LiFePO4 (LFP, lithium iron phosphate) or NMC (nickel manganese cobalt). All three current ~1 kWh models we pinned use LFP.
What the manufacturers state for their LFP models
| Model | Chemistry | Rated cycle life | Source |
|---|---|---|---|
| EcoFlow DELTA 3 Plus | LFP | 4000 cycles to 80+% capacity | https://us.ecoflow.com/products/delta-3-plus-portable-power-station |
| Jackery Explorer 1000 v2 | LiFePO4 | 4000 cycles to 70%+ capacity | https://www.jackery.com/products/jackery-explorer-1000-v2 |
| Anker SOLIX C1000 | LiFePO4 | 3,000 cycles to 80%+ capacity | https://www.ankersolix.com/products/c1000 |
| EcoFlow DELTA Pro 3 | LFP | 4000 cycles to 80% (0.5C/0.5C at 25°C) | https://us.ecoflow.com/products/delta-pro-3-portable-power-station |
Note the end-of-life thresholds differ (70% vs 80%), so the cycle numbers are not directly comparable.
NMC side
Jackery's own FAQ gives a like-for-like pair: the Explorer 1000 Pro (NMC, an earlier model) and the Explorer 1000 v2 (LiFePO4).
| Spec (Jackery FAQ) | Explorer 1000 Pro | Explorer 1000 v2 |
|---|---|---|
| Battery type | Lithium-ion (NCM) | LiFePO4 |
| Capacity | 1002 Wh | 1070 Wh |
| Rated cycle life | 1000 cycles to ≥80% | 4000 cycles to ≥70% |
| Weight | ~11.5 kg | ~10.8 kg |
| Self-discharge (Jackery's figure) | ~5–10% per month | ~1–3% per month |
Jackery writes "NCM", the same nickel-cobalt-manganese chemistry often called NMC.
What this pair shows, and only for these two models: Jackery rates its NMC unit for 1000 cycles to 80% and its LFP unit for 4000 cycles to 70%. The end-of-life thresholds differ, so the numbers are not a direct 4× comparison. In this pair the LFP unit is also the lighter one per Wh (about 10.1 g/Wh vs 11.5 g/Wh), so the pair does not show NMC as lighter. Newer design, not chemistry alone, may explain that.
We do not make general claims about energy density or safety for either chemistry, because we have not found an official or standards source for them.
