Iota Manual

The IOTA IQ-LIFEPO Charge Controller installs
by simply plugging the IQ cord into the Dual Volt-
age jack located on the DLS* (Refer to Figure A).
The IOTA IQ-LIFEPO circuitry is then automatically
engaged. Note: the cord provided is specifically de-
signed for use with the IOTA IQ-LIFEPO. Do not use
the IOTA IQ-LIFEPO with any cord other than one
supplied with the unit.

The IOTA IQ-LIFEPO Charge Controller is designed for automatic charging control for DLS
Battery Chargers with LiFePO4 battery applications, providing enhanced battery charging and
maintenance. The IOTA IQ-LIFEPO allows the DLS Charger to operate as an automatic “smart
charger” that gives the customer the benefit of automatic Bulk, Float, and Maintenance cycles.
Multi-stage charging with the IQ-LIFEPO increases the charging capacity of the DLS charger,
decreases the charge time, and ensures a maintained and full battery charge. The IOTA IQ-LIFE-
PO monitors the battery at all times. If the DLS voltage remains in the Float stage for fifteen
days, the IOTA IQ-LIFEPO will automatically initiate the Maintenance Cycle for a predetermined
time to help maintain the battery, and then resume float stage charging. ATTENTION: While the
IQ-LIFEPO is designed to accommodate most LiFePO4 battery and BMS systems, always
refer to the manufacturer’s specifications for your batteries allowable charging parameters.
INSTALLATION
The LED Indicator on the IQ informs the user of the DLS charging state and the battery charge
status. When first activated, the IQ will read the number of cells in the battery and indicate the
voltage of the battery through a number of flashes. Refer to Figure C.
LIT/FLASHING LED - After detecting the battery, the IQ-LIFEPO will initiate a Bulk Charge phase.
When the IQ-LIFEPO is in the Bulk Charge mode, the green LED indicator will flash rapidly (ap-
prox. 2 flashes per second). When the Bulk Charge is complete, the IQ-LIFEPO will begin the
Float Charge phase and the LED will remain lit (no flashing). Refer to Figure B for Charge Stage
descriptions.

MAINTENANCE
The Bulk State charges the battery at the
full-rated output of the charger, reducing
the time it takes to charge the battery.
Once the battery has been fully charged, the
charger remains in the Float State, monitoring
the battery for drop in voltage.
If the battery has remained in the Float State for
15 days, the IQ automatically provides reinitiates
a bulk charge to ensure the battery remains in a
completely charged condition.
