Safety Guidelines

WARNING 

To avoid fire, serious injury, or property damage, follow the following safety rules and guidelines 
when using, charging, or storing your batteries.

1.  

DO NOT allow the Delta to come into contact with any kind of liquid. DO NOT leave the Delta out in the 

        

rain, dew or near a source of moisture. DO NOT drop the Delta into water. If the Delta comes into contact 
with water, chemical decomposition may occur, potentially resulting in the battery catching on fire, and     
possibly leading to an explosion.

2.  

The Delta Unit is not User Serviceable. DO NOT attempt to disassemble the Delta and never attempt to 

replace the internal batteries with Non- EcoFlow batteries. EcoFlow takes no responsibility for any 
damage caused by unauthorised disassembly of the Delta or any damage caused as a consequence of 
repairs attempted. Repairs may only be conducted by EcoFlow, or its authorised Service agents. 
Contact EcoFlow support at [email protected] for further assistance.

3.  

DO NOT use or charge a swollen, leaky, or damaged or malfunctioning Delta. If your Delta is functioning 

abnormally, contact EcoFlow support at [email protected] for further assistance.

4.  

The Delta must only be used at temperatures between 0 and + 45 degrees centigrade. Discharge or 

Charging of the Delta should not be undertaken outside these temperature ranges. Use in environments 
above 45 degrees centigrade can lead to fire or explosion. Using the Delta below 0 degrees centigrade
will severely reduce the product’s performance. Allow the Delta to return to a normal operating 
temperature before use.

5.  

DO NOT use the Delta in strong electrostatic or electromagnetic environments. Otherwise, the Delta 

control board may malfunction and cause a serious damage to the Delta or a serious accident during use.

6.  

DO NOT disassemble or pierce the Delta in any way. Otherwise, it may leak, catch on fire, or explode.

7.  

Electrolytes in batteries used in the Delta are highly corrosive. If any electrolytes come into contact with 

your skin or eyes, immediately wash the affected area with fresh running water, and then see a doctor 
immediately.

8.  

DO NOT use a Delta if it has been involved in a crash, has been dropped or a suffered a heavy impact. 

Contact [email protected] for further assistance

9.  

If the Delta falls into water during use Do Not touch the Delta or the water, as lethal Voltages may be 

present.  Only if safe the Delta should be removed form the water as soon as possible and put it in a safe 
and open area on a non-combustible surface. Maintain a safe distance from it until it is completely dry.
