The freas type are hard to read... Why I dont own one..
Interesting info on the iota..
The trigger points seem great IMO.. But does that 12.8 trigger bulk mode?
BULK STAGE - During this state, the charger will operate either at Full Current output or Constant Voltage output
depending on the discharged state of the battery. A discharged battery will dictate the voltage and force the charger
into constant-current operation. As the battery charges, the charger transitions to a constant-voltage operation.
This BULK STAGE will continue for either 225 minutes or until the battery voltage reaches the “High Trigger” value
(whichever occurs first). At this point, the BULK STAGE will operate for another 15 minutes before switching to the
ABSORPTION STAGE.
ABSORPTION STAGE - This state is limited to 240 minutes (4 hours) during which the charger will operate either at
Full Current output or Constant Voltage output depending on the discharged state of the battery. During Full Current
output, the charger is providing its full current rating and will slowly increase the battery voltage to the “Absorption
Stage” voltage. At the end of the 240 minutes, the charger will revert to the FLOAT STAGE.
FLOAT STAGE - This charge state holds the batteries at Constant Voltage for a period not longer than seven days.
During this state, the charger not only floats the batteries, but it can also provide load current up to its maximum
rating for other loads without depleting the battery capacity. The FLOAT STAGE will end when either the battery voltage
drops below the “Low Trigger” point or at the end of seven days when the IQ4-X initiates an equalization stage
to remove sulfate layers from the battery plates.
