Key facts
- All-in-one 20 ft DC container made entirely in Europe (Wroclaw, Poland) from cell to system; energy 'around 5 MWh', more than double the energy density of the previous JF1 DC LINK
- JF2S pouch LFP cell offers 2.7× the energy of the JF1 cell and up to 15,000 cycles; JF2S pack is stackable (three modules per unit) with thermal barriers and liquid cooling plates
- Zarnowiec (PGE, Poland) project 262 MW / 981 MWh: 204 DC-Link container units of ~45 t each, all manufactured in Poland; deliveries April–July 2026 (unit name not stated in that release)
- A related 'JF2 DC LINK 5.0' for the Korean market was shown at InterBattery 2026 (first Korean LFP grid ESS); no specifications published
- No datasheet online: exact energy, power, voltage, dimensions, weight and certifications not published
