12.8V 100Ah Inverter Battrey with Display

12.8V 100Ah Inverter Battery Pack with Display

The 12.8V 100Ah Inverter Battery Pack with Display is a LiFePO4 energy-storage battery for compatible 12V-class inverter, UPS, solar-backup and standby-power systems. Its 12.8V nominal voltage and 100Ah rated capacity provide approximately 1.28kWh of nominal stored energy, making it a practical battery size for residential and light-commercial backup applications.

The integrated display is the main differentiator of this version. It gives the user an on-pack visual reference for routine battery checks during charging, commissioning, service and daily backup operation. This is useful where the battery is installed in an accessible location and local status visibility is preferred instead of relying only on the inverter or an external meter.

Technical Details

A 12.8V LiFePO4 battery uses the common four-series-cell voltage architecture known as 4S. With 100Ah capacity, the pack stores about 1,280Wh of nominal energy before conversion losses. Real backup time depends on the connected load, inverter efficiency, wiring losses, discharge limits and operating conditions, so watt-hours are more useful than amp-hours alone when estimating runtime.

LiFePO4 chemistry is widely used for inverter and stationary backup service because it provides a stable working voltage and supports repeated charge-discharge operation. A complete lithium inverter battery also relies on battery management to control the series cell group during charging and discharging. Battery voltage, inverter input range, charger profile, cable size, fuse protection and expected DC current should therefore be treated as one complete electrical system.

The display adds local visibility without changing the fundamental 12.8V/100Ah rating. It is especially useful during commissioning and maintenance because the operator can inspect the battery directly before checking the rest of the power system.

This battery belongs to the 12V-class lithium inverter category and is intended for equipment designed around a 12.8V LiFePO4 battery. The inverter or charger should use a compatible lithium charging profile, while DC cable and fuse sizing should match the actual current and installed cable length.

The 100Ah rating describes stored-charge capacity, not inverter power. A higher-wattage inverter can demand substantial current from a 12.8V battery, so battery current capability, BMS rating, terminal connection and cable sizing must support the intended load. Choose the display version when quick local battery visibility is useful at the installation point.

Applications

• Home inverter and household backup systems designed for 12.8V lithium batteries.

• UPS and emergency backup installations for compatible electronics and office loads.

• Solar energy-storage systems using lithium-compatible 12V charging equipment.

• Shops, offices and workstations requiring compact backup energy storage.

• Compatible upgrades from conventional 12V battery platforms to LiFePO4 technology.

Installation Guide

Install the battery in a stable, dry and ventilated location with terminals protected from accidental short circuits. Confirm polarity before connecting the inverter or charger. Use correctly sized DC cable, secure lugs and suitable overcurrent protection. Configure the inverter or charger for a LiFePO4-compatible charging profile before normal operation.

Avoid mixing batteries of different chemistry, capacity, age or state of charge in the same bank unless the complete system is designed for that arrangement. During commissioning, confirm normal charging and discharge behavior before applying the full intended load.
