SAKO Li-Max 12.8V 200Ah LiFePO4 Lithium Battery 2560Wh

Product Overview

The SAKO Li-Max 12.8V 200Ah LiFePO4 Lithium Battery is designed for energy storage applications that require a rechargeable battery with substantial capacity, high discharge capability and a long cycle life. With a nominal voltage of 12.8V and a capacity of 200Ah, it provides 2560Wh (2.56kWh) of nominal energy.

Using Lithium Iron Phosphate (LiFePO4) chemistry, this battery is intended for compatible energy storage and backup power applications. Its built-in hardware Battery Management System (BMS) provides multiple protection functions to support safe battery operation.

2560Wh Energy Capacity

The SAKO Li-Max battery combines a 12.8V nominal voltage with a 200Ah nominal capacity. Its 2560Wh energy rating makes it an option for suitable low-voltage energy storage systems.

Actual runtime depends on the connected equipment's power consumption, inverter efficiency, operating temperature and usable battery energy. For example, a system's runtime should be calculated using the actual load and conversion losses rather than nominal capacity alone.

LiFePO4 Battery Technology

The battery uses Lithium Iron Phosphate (LiFePO4) chemistry and has a specified cycle life of 6000+ cycles under the manufacturer's stated test conditions: 0.2C, 25°C and 100% depth of discharge (DOD).

Cycle life in practical use can vary with charging and discharging conditions, temperature, storage practices and operating limits. Following the manufacturer's charging guidelines is important for achieving reliable long-term performance.

High Discharge and Charging Capability

The SAKO Li-Max 200Ah battery supports a maximum continuous discharge current of 200A and a maximum pulse discharge current of 300A for 1 second. Its maximum continuous charging current is 100A.

These ratings are useful when matching the battery to a compatible inverter, DC load or charging system. The equipment must remain within the battery's voltage and current limits. The pulse rating is short-duration only and should not be treated as a continuous operating rating.

Built-in Battery Management System

The integrated hardware BMS includes protection against:

• Overcharging

• Overdischarging

• Overcurrent

• Short circuits

• Excessive temperature

These functions help protect the battery under supported fault conditions. Correct wiring, suitable fuses or circuit breakers, and a compatible charger remain important for a safe installation.

Voltage and Environmental Specifications

The battery has a stated voltage window of 11.2V–14.6V and a float charge voltage of 14.0V. The specified working temperature range is -10°C to +50°C.

Its IP65 rating indicates protection against dust ingress and water jets under defined test conditions. It should still be installed according to the manufacturer's instructions and should not be assumed to be suitable for immersion in water.

Physical Design and Applications

Measuring 522 × 218 × 238mm and weighing 27kg net, the battery uses M8 terminals for electrical connections.

Depending on system compatibility, potential applications include:

• 12V backup power systems

• Compatible solar energy storage systems

• Off-grid power applications

• Recreational vehicle and mobile power systems

• Marine or outdoor equipment where the installation requirements are met

• Compatible DC power systems

Before connecting the battery to an inverter or solar charge controller, verify the supported battery voltage, charging profile, maximum current and connection requirements.
