6.2.3 Battery Pre-Discharging
Battery pre-discharging is a function to limit discharging current temporarily before the battery begins
to discharge at high current. This will protect the capacitors of external electrical devices from being
damaged by instantaneous high current. 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 discharge current limit,
and the battery can discharge at high current normally.
6.3 Battery Auto-Heating
6.3.1 Charge Heating
The EcoFlow LFP Battery is built with charge heating function to work in low temperature environment.
Charge heating is automatically activated when 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 charging input ≥ 250 W. When the battery internal temperature rises above
5°C (41°F), the battery can start charging process.
2. When the battery internal temperature rises above 10°C (50°F), charge heating stops, and battery
charging continues.
* The charge heating function works in temperature range of -20°C~0°C (-4°F~32°F).
6.3.2 Discharge Heating
The capacity of the battery can be significantly reduced when discharging at high power in low temperature.
The EcoFlow LFP Battery is built with discharge heating function to address this situation. Discharge heating
function can be activated manually by tapping the discharge heating button in the EcoFlow App as follows:
1. When the battery internal temperature is below 0°C (32°F) and the battery SOC ≥ 70%, tap the discharge
heating button in the EcoFlow App to activate the discharge heating.
2. When the battery SOC ≤ 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 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 temperature environment, if the battery automatically switches on the discharge
heating function, this can lead to frequent depletion of the battery itself.
6.4 Connecting Batteries in Parallel
6.4.1 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 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.
