Overview
The YueQi 25.6V lithium iron phosphate (LiFePO4) series is an 8-cell pack for 24 V class storage systems. It sits between the 12.8V and 51.2V families and suits users who need higher bus voltage without moving to a full 48 V architecture. The catalog lists three capacities: 100Ah, 200Ah and 300Ah.
The pack keeps a nominal 25.6 V output across its discharge range and is rated for a working window of 22 V to 29.2 V. Parallel connection is listed in the catalog for up to 10 units, subject to confirmation of the BMS and wiring method for each project.
Typical Applications
- Solar storage for off-grid and hybrid systems using a 24 V class inverter
- Backup power and load shifting for small commercial and residential sites
- Mobile power platforms that need more energy than a 12.8V pack provides
- OEM integration into energy storage cabinets and mobile power products
Key Features
- 8 cells in series, 25.6 V nominal, 29.2 V full-charge window
- Stored energy of 2560 Wh, 5120 Wh and 7680 Wh for the three listed capacities
- Catalog protection functions include over-voltage, over-current, over-charge, over-discharge, short circuit, reverse-charge and temperature protection (to be confirmed against the BMS datasheet)
- Communication interface: not listed for this series in the catalog (to be confirmed)
