Key facts
- Built from 314 Ah cells in 1P104S liquid-cooled battery packs; 1500 V battery system, pack withstand voltage 4380 VDC
- CALB claims 35% higher volumetric energy vs previous generation and 20% longer cycle life
- Pack-level IP67 (dust/water/condensation), sand and fog protection; system-level flooded water fire suppression
- Energy efficiency 95% (charge/discharge) and 15-year lifespan stated at All-Energy Australia 2025; 'UL and IEC' certifications named without numbers
- Variable-frequency thermal management said to cut auxiliary consumption by 20%
What CALB does not publish for this model
These fields are empty because no public datasheet or release states them. That is information too: ask for these numbers before you shortlist.
