640Wh 12.8V 50Ah LiFePO4 Battery With IP55 Iron Case UPS Backup Battery

640Wh 12.8V 50Ah LiFePO4 Battery with IP55 Iron Case and UPS Backup Design

This compact 12.8V LiFePO4 battery provides 640Wh of nominal energy for UPS backup, emergency lighting, small solar systems and other compatible 12V applications. Its 50Ah format offers a lithium battery option for projects upgrading from selected lead-acid or gel batteries.

The battery is supplied as a standalone DC power pack. A compatible charger, inverter or DC load controller must be selected separately according to the equipment voltage and operating current.

Compact Lithium Power for Small Backup Loads

The 640Wh capacity is suitable for controlled loads such as lighting, communication devices, monitoring equipment and small UPS systems. Actual operating time depends on total power consumption, conversion losses and the battery reserve retained by the connected equipment.

When replacing an existing 12V battery, buyers should compare the charger voltage, discharge current, terminal arrangement, enclosure dimensions and available installation space rather than selecting by capacity alone.

Charging and Discharging Requirements

The recommended maximum charging-voltage range is 14.0–14.6V. The listed standard charging current is 10A, while the maximum charging current is 25A.

The documented discharge current is 50A, with a 10V discharge cut-off reference. The charger and connected equipment should remain within these battery limits.

Iron Enclosure with IP55 Protection

The iron enclosure measures 230 × 145 × 210mm and weighs approximately 4.5kg. Its compact dimensions support installation in small equipment compartments and protected backup-power areas.

The IP55 rating provides resistance to dust and water jets under suitable installation conditions. Cable connections should remain properly protected, and the battery should not be submerged or placed where water can accumulate.

Compact 12V Battery FAQ

Can it replace an existing 12V lead-acid battery?

It may be used as an upgrade when the charger voltage, current, dimensions and connected equipment are compatible with LiFePO4 batteries.

Is 640Wh suitable for long-duration backup?

It is intended for smaller controlled loads. Required runtime should be calculated from the total watt-hour consumption.

What type of charger should be selected?

Use a compatible LiFePO4 charger that follows the documented 14.0–14.6V charging-voltage range.

Can the battery remain exposed to rain?

IP55 provides limited water resistance, but terminals and cable connections should remain protected from prolonged exposure or standing water.

What information is needed for an OEM quotation?

Provide the application, load current, charger specification, required enclosure arrangement and order quantity.
