IOTA IQ4 Smart Charge Controller

The IQ4 Smart Charge Controller provides intelligent automatic charging control for your DLS Battery Charger, keeping your batteries fully charged and in peak condition. The IQ4 Smart Charge Controller allows the DLS to operate as an automatic 4-stage "smart charger," delivering the charge your battery needs at the time it needs it. Simply plug the IQ4 cord into the dual voltage jack on the DLS Battery Charger.

IOTA IQ4 Smart Charge Controller Charging Stages

  • Bulk Stage
    Allows the batteries to be charged from the full rated output of the charger (for example, a 12V charger will charge at a maximum of 14.8V). This increased charging period reduces the overall charging time of the battery.
  • Absorption Stage
    After the bulk stage, the IQ4 moves to the absorption stage (14.2V for a 12V battery). This mode will continue for up to 8 hours to ensure that the battery receives a complete charge.
  • Float Stage
    During the float stage, the IQ4 reduces the DLS charge voltage. This reduced voltage maintains the full charge while minimizing gassing of the battery. The IQ4's float stage prevents boiling and bulging of the battery caused when the battery is exposed to higher charging voltages for too long.
  • Equalization Stage
    If the batteries remain in float stage for a 7-day period, the IQ4 will switch the DLS charger into a pre-programmed equalization stage. This protects the life of your battery by dissolving any sulfate layer on the battery's internal plates and avoids stratification that can occur when a battery has not been in use for extended periods.
