IMPORTANT NOTE:

 Circuit Breakers, Disconnects and Fuses should be employed 

throughout several points of a power storage and generation installation to effectively isolate 

and protect all components of the system to safeguard against faults, short circuits, polarity reversals 
or a failure of any component in the overall system. Fuses, breakers, wiring ratings and values should 
be determined by established standards and evaluated by certified electricians, licensed installers, 
and regional code authorities. The Fortress Lithium Batteries must always be installed with a charge 
controller and the appropriate settings to protect the batteries from open PV voltage and other high 
voltage charging sources. The Fortress Battery Management System (BMS) alone will not protect the 
batteries from these extreme electrical phenomena. Failure to adhere to installation protocol will void 
the Warranty. 
 

CAUTION! Verify polarity at all connections with a standard voltmeter before 
energizing the system. Reverse polarity at the battery terminals will void the Warranty 

and destroy the batteries. Do not short circuit the batteries.

 

Most batteries pose some risk of shock or sparking during the installation and initial wiring and 
connection process. Wearing insulated gloves, clothing and footwear and using electrically insulated 
tools are required when working with Fortress Power Lithium Batteries. Cover, restrain or remove 
jewelry or conductive objects (metal bracelets, rings, belt buckles, metal snaps, zippers, etc.) when 
working with any electrical or mechanical device. Cover or restrain long hair and loose clothing when 
working with any electrical or mechanical device.   

2. IMPORTANT NOTES 

2.1 Transportation and Handling 

Do not knock, drop, puncture, or crush the battery; Do not expose battery to flames, incinerate or 
direct sunlight; Do not open battery case or disassemble the battery; Do not lift battery by the terminal 
cables; Do not vibrate battery; Do not expose battery to water or other fluids; Do not expose battery to 
open flame; Do not place the product nearby highly flammable materials, it may lead to fire or 
explosion in case of accident; Store at cool and dry place. Do not store in greenhouses and storage 
areas for hay, straw, chaff, animal feed, fertilizers, vegetables or fruit products; Store the product on a 
flat surface; A ventilated area is strongly recommended for handling the product; Store the product 
out of reach of children and animals; Store the product where it should be minimal dust and dirt in the 
area; do not transport battery upside down. Do not disassemble the battery or change the structure of 
the battery by yourself.
