Usage Instructions
- Proper Connection: Always follow the connection instructions to avoid irreversible damage. Start connecting from B- and proceed to higher positions.
- Avoid Contamination: Ensure that no copper or tin bits cling to the guard shield during soldering.
- Secure Installation: Use hard epoxy sheets as a barrier to prevent short circuits caused by squeezing.
- Optimal Wire Selection: Choose power supply lines with the appropriate diameter to prevent excessive temperature rise and voltage drop during high-current discharge.
- Safety Precautions: Install the guard shield in the battery box with proper insulation, heat dissipation, and tightness to avoid internal short circuits
