The IQ4 Smart Charge Controller plugs into the dual voltage jack of an IOTA DLS Battery Charger to provide intelligent automatic charging control by progressing through the four charging stages outlined below. These intelligent deep-cycle battery charging algorithms help extend the life of your batteries and are especially valuable when you need to maintain batteries in storage for an extended period of time.
Note: the IQ4 is not compatible with IOTA DLS chargers that feature internal IQ charge control.
