Usage and Attention:

  • After purchasing the protection mould, users should connect lines in compliance with the instruction.
    • Voltage usually exists in the battery, so operators should peel one line and then connect another starting from B-.
    • Lines should be connected from the low position to the high position with no mistake of order, or the irreparable damage could be caused.
  • When lines get connected, bits of copper and tin should not cling to the guard shield.
  • Protection board should be connected to battery group with compliance to specifications and any leading line should not be put on the back of the board but on the lateral side.
  • When equipping the guard shield, hard epoxy sheer should be fixed on the back of the board as the barrier to prevent the squeezing against short circuit.
  • When welding output lines, power supply line with the proper diameter should be chosen to prevent great temperature rising and great dropping of line voltage while high current discharges.
  • The guard shield is usually fixed in the battery box. Insulation, heat relief and tightness should be a great concern, the internal short circuit could lead to some danger.
  • The full-charged battery group should be put properly out of children's reach.
  • If any unusual condition appears during the using process, please stop using the product immediately.
