8. Battery Maintenance and Disposal
8.1 Maintenance Instructions
1. The battery must be stored in 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 of time, 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 temperature above 45°C (113°F) or below 20°C
(68°F).
4. When the temperature of 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 of time 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 being left idle for too long, it will enter deep sleep mode and
will need to be recharged before it can be used again.
8.2 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 the
battery directly. Contact a specialized battery recycling company for further disposal.
3. An over-discharged battery cannot be switched on. Please dispose the battery according to local
laws and regulations.

10. Frequently Asked Questions
1.
What type of battery chemistry is used in this product?
This product uses high quality lithium iron phosphate.
2.
How do I clean the battery?
The battery can be wiped with a dry, soft, and clean cloth or tissue.
3.
Are lithium batteries safe?
The EcoFlow LFP Battery is protected by high-performance BMS and have undergone rigorous
testings to ensure safety in use.
Can the 5KWh LFP Battery and 2KWh LFP Battery be used in parallel?
4.
This is not recommended — when using two models in parallel, the consistency of the batteries
cannot be guaranteed, which can lead to shortened life span of the batteries or even a safety hazard.
5.
Can I charge the battery at low temperature?
Yes, when the battery is being charged at low temperature -20°C ≤ T ≤ 0°C (-4°F ≤ T ≤ 32°F), the
charge heating function is switched on prior to heat the battery before it is charged normally.
6.
Can the battery be used with third-party power systems?
Yes, the user will need to perform extra wiring for this.
7.
How do I store the battery?
When storing the battery, first switch it off and then store it in a dry, ventilated place at room
temperature and stay away from water sources.
8.
Can the battery be heated when charging with MPPT at ambient temperature below 0°C (32°F)?
Yes. Depending on the intensity of solar radiation and the power of the solar panel used by the user.
It is recommended to connect to at least 400W of solar panel(s).
