Charging and Discharging the Battery Connecting the Battery to the EcoFlow Power Kits

Connect the battery to Power Kits for charging (as follows):

Connecting the Battery to Third-Party Power Systems

• EcoFlow LFP Battery is compatible with most commercially available 40V~60V third-party power systems.
• The user can monitor the operating status of each battery by connecting the EcoFlow Power Kit Console or EcoFlow Wireless Communication Dongle via the RJ45 port.
• EcoFlow Power Kit Console or EcoFlow Wireless Communication Dongle must be purchased separately.
• The user should select the appropriate connection cable according to the power of the third-party power system and the discharge current of the battery.

The following table shows the load capacity of different battery connection cables:

Battery Pre-Discharging

• Battery pre-discharging is a function to limit the discharging current temporarily before the battery begins to discharge at a high current.
• This will protect the capacitors of external electrical devices from being damaged by instantaneous high currents.
• Once connected, a current-limiting resistor in the battery allows the capacitors of external electrical devices to charge slowly.
• When the capacitor voltage rises to 90% of the battery voltage, the battery management system removes the discharge current limit, and the battery can discharge at a high current normally.

Battery Auto-Heating Charge Heating
The EcoFlow LFP Battery is built with a charge-heating function to work in low-temperature environments. Charge heating is automatically activated when the ambient temperature is below 0°C (32°F) and the battery is in charging mode. The activation sequence is as follows:

1. Charge heating requires a charging input of 250 W. When the battery’s internal temperature rises above 5°C (41°F), the battery can start the charging process.
2. When the battery’s internal temperature rises above 10°C (50°F), charge heating stops and battery charging continues.
   • The charge heating function works in the temperature range of -20°C~0°C (-4°F~32°F).

Discharge Heating
The capacity of the battery can be significantly reduced when discharging at high power at low temperatures. The EcoFlow LFP Battery is built with a discharge heating function to address this situation. The discharge heating function can be activated manually by tapping the discharge heating button in the EcoFlow App as follows:

1. When the battery’s internal temperature is below 0°C (32°F) and the battery SOC is 70%, tap the discharge heating button in the EcoFlow App to activate the discharge heating.
2. When the battery SOC is 50% or the battery internal temperature is higher than 10°C (50°F), the discharge heating function is automatically switched off. The discharge heating function works in the temperature range of -20°C~0°C (-4°F~32°F).

Why can’t the battery automatically activate the discharge heating function?

• Unlike charge heating which consumes power from the charging source, discharge heating consumes power from the battery.
• In low low-temperature environment, if the battery automatically switches on the discharge heating function, this can lead to frequent depletion of the battery itself.

Connecting Batteries in Parallel Charging and Discharging in Parallel
Connecting Batteries in Parallel via the EcoFlow Power Hub The EcoFlow LFP Battery is a 48V battery system and only supports parallel connection. Up to three EcoFlow LFP Batteries can be connected to the EcoFlow Power Hub at the same time. The EcoFlow LFP Battery Power Cable has a preset communication signal, allowing paralleled batteries to communicate with each other. Do not use the battery in series as this can potentially damage the battery.

1. Ensure the battery is switched off before connection.
2. Connect the battery to the EcoFlow Power Kits via the EcoFlow LFP Battery Power Cable as shown in the diagram below.

Battery Management System
The battery is equipped with a battery management system (BMS) and has the following battery protection features:

When protection is triggered, disconnect the battery and leave it for some time before restarting it.

Replacing the Fuse

• The EcoFlow 5KWh LFP Battery has a built-in DC 70-V/150-A replaceable fuse, while the 2KWh LFP Battery has a built-in DC 70-V/125-A replaceable fuse.
• Under normal operating conditions, there is no risk of fuse blowing.
• When an external short circuit occurs and the battery management system is not protected in time, the fuse will blow immediately to protect the battery.
• When a short circuit occurs and the battery cannot be charged or discharged, the fuse must be replaced.

The replacement procedure is as follows:

1. Ensure the battery is switched off, open the fuse cover using a suitable tool, and keep the cover in a safe place.
2. Replace the fuse then install the cover back.

Battery Maintenance and Disposal

Maintenance Instructions

1. The battery must be stored in a dry and well-ventilated environment. If the storage temperature is too high or too low, this will affect the self-discharge rate of the battery and accelerate the natural aging of the battery. It is therefore recommended to store the battery at a temperature of 20~45°C (68°F~113°F) and stay away from water sources, heat sources, and metal objects.
2. If the battery is not going to be used for a long period, it is recommended to be stored intact in a semi-charged state (60% SOC). The battery is recommended to be discharged to 30% and then recharged to 60% every three months.
3. For safety reasons, the battery must not be stored at temperatures above 45°C (113°F) or below 20°C (68°F).
4. When the temperature of the battery is equal to or below -20°C (-4°F), the battery cannot be used for charging, discharging or heating.
5. To extend the service life of the battery, the battery is recommended to be used at 20°C (68°F) to 45°C (113°F).
6. If the battery level is below 1% after use, it should be charged to 60% before storage. If the battery is left idle for a long period with critically low SOC, irreversible damage to the battery cell will occur, reducing the service life of the battery.
7. If the battery SOC is critically low and is left idle for too long, it will enter deep sleep mode and will need to be recharged before it can be used again.

Disposal

1. If conditions permit, make sure that the battery is completely discharged before placing the battery in the designated battery recycling bin. The battery cells, which contain hazardous chemicals, are strictly prohibited from being placed in an ordinary garbage bin. For relevant details, please comply with the user’s local laws and regulations regarding lithium battery recycling and disposal.
2. If the battery cannot be fully discharged due to the fault of the product itself, do not dispose of the battery directly. Contact a specialized battery recycling company for further disposal.
3. An over-discharged battery cannot be switched on. Please dispose of the battery according to local laws and regulations.
