IMPORTANT SAFETY INSTRUCTION
-
Please keep the battery away from heat sources, sparks, flames, and hazardous chemicals.
-
Maintain Adequate Ventilation and Heat Dissipation Place the battery in a well-ventilated area with sufficient heat dissipation to prevent overheating and damage.
-
Size the Battery Cables and Connectors Appropriately
Use high-stranded copper connectors and heavy gauge cables to handle possible battery loads. Make sure to keep identical cable lengths.
Avoid accidents caused by unsuitable connectors or cables that make the connection a heat source during battery operation. -
Please tighten all cable connections, as loose cable connections can cause terminal meltdown or fire.
-
DO NOT puncture, drop, crush, burn, penetrate, shake, or strike the battery.
The battery should be securely fastened during handling to prevent impact or dropping.
It should be safely secured to a solid plane and the cables safely tied to a suitable location to avoid arcing and sparking due to friction.
DO NOT press it by placing heavy stuff on top of it for long periods, which may damage it due to an internal short circuit. -
DO NOT immerse the battery in water whether the battery is in use or on standby.
-
DO NOT open, dismantle, or modify the battery.
-
DO NOT touch the exposed electrolyte or powder if the battery casing is damaged.
-
Uncovered electrolyte or powder that has contacted the skin or eyes MUST be flushed out with plenty of clean water immediately.
Seek medical attention afterward. -
Avoid Short Circuit
Please use circuit breakers, fuses, or disconnects that have been properly sized by certified electricians, licensed installers, or regional code authorities to protect all the electrical equipment in your system. The battery has a built-in battery management system (BMS) that protects the battery cells from over-charge, over-discharge, and over-current, however this alone will not protect your system from severe electrical conditions. -
Trained and certified technicians are required for safe and reliable installation. This product manual can only serve as a guideline as it cannot cover all possible scenarios.
-
Verify Correct Polarity
Please verify the polarity before connecting the wiring. Reverse polarity can and will destroy the battery and other electrical equipment. Use a multimeter to determine proper polarity. -
Avoid Exposed Metal Terminals or Connectors
The terminals of this battery are always live. Avoid exposed metal terminals or connectors; DO NOT place tools on the terminals or touch them with bare hands; DO NOT short circuit or use outside of specified electrical ratings. -
DO NOT dispose of the battery as household waste. Please use recycling channels in accordance with local, state, and federal regulations.
WARNING
- Batteries are potentially dangerous and proper precautions must be taken during operation and maintenance.
- Improper use of the battery can lead to battery failure or other potential damage.
- Improper configuration, installation, or use of related equipment in the battery system may damage the battery and other related equipment.
- Please wear proper personal protective equipment when working on the battery.
- Battery installation and maintenance must be performed by trained and certified technicians.
- Failure to follow the warnings above can result in potential damage.

Leave them together for 12~24hrs until the battery voltages have been balanced, the paralleled battery system can be connected to the load.
Copper Bar: Flat metal made of copper. It can help ensure the input &output currents of each battery are balanced. Copper is recommended as it has better conductivity, and the conversion efficiency of the input & output currents for the battery will be higher.
Step 3 Complete the System Connection
Connect the and of the load to the copper bars. The cable gauge used in this
step should be able to support the total input & output current of the entire
battery system.
