12.8V LiFePO4 Battery Series

Overview

The YueQi 12.8V lithium iron phosphate (LiFePO4) series is a 4-cell pack built for solar storage, off-grid backup and mobile power projects that need a 12-volt nominal bus. Each pack is rated at 12.8 V nominal and is offered in 100 Ah, 150 Ah and 200 Ah capacities in the current catalog. A 300 Ah variant also appears in the catalog and is listed below with its figures marked for confirmation.

LiFePO4 chemistry gives a flat discharge curve around 12.4 to 13.2 V for most of the capacity, which keeps connected inverters and loads in a steady voltage window. The pack is designed for deep cycling and daily charge and discharge rather than for short bursts only.

Typical Applications

• Solar home and off-grid storage, paired with a 12 V or 24 V inverter
• Backup power for communication, monitoring and control equipment
• Mobile and vehicle-mounted power systems that use a 12 V bus
• Replacement of lead-acid packs in existing 12 V systems, subject to charger and BMS review

Key Features

• LiFePO4 cell chemistry with a 14.6 V charge voltage for a 4-cell pack
• Battery management with protection against over-charge, over-discharge, over-current, short circuit and temperature events (protection list to be confirmed against the BMS datasheet)
• Reverse-charge protection listed in the catalog
• Cycle life stated in the catalog as more than 2,000 cycles (to be confirmed in writing)
