The IOTA IQ-4INT/EXT 4-Stage Charge Controller is an automatic charging control for your DLS Battery Charger. This intelligent, 4-stage charger will keep your batteries fully charged and operating for a longer life. If your DLS charger does not have a built-in IQ4 control, this IQ4 controller is a must-have for elongating your DLS's battery life.
- Prevents gassing, boiling and bulging of batteries
- Flashing LED to indicate charging stage
- Dimensions: 1.3" x 2.6" x 0.7"
- 2-Year warranty
1. Bulk Stage: The bulk stage of the IQ4 allows the batteries to be charged from the full rated output of the charger, allowing for increased charging period reduces the overall charging time of the battery.
2. Absorption Stage: After the bulk stage, the IQ4 then moves to the absorption stage. This mode will continue for up to 8 hours to ensure that the batterty receives a complete charge.
3. 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.
4. Equalization Stage: If the batteries remain in a "float stage" for a 7-day period, the IQ4 will switch the DLS charger into a pre-programmed the equalization stage. This protects the life of your battery by dissolving any sulfate 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.
