27DCs and SG Lag Problems
Here is what I mean. Got two rebuilt 27DCs from Interstate as "Econo Power" models, which means they are whatever brand and type they decided to renew and sell at under half price. So just right fo...

Not really IMO. What you want is for it to get the batts to 14.8 and hold them there at 14.8 for a length of time as the absorption voltage. Dropping to 14.2 to do that is contrary to the charging specs for many battery brands and types of battery.
Your PD with CW will do a better job on your new 6s even at 14.4.
The Iota's IQ4 does not have that boost button like your CW has, so you cannot make it stay at 14.8.
Says 4 hours bulk or high trigger..14.8
Then 8 hours absorp at full current or constant voltage 14.2.
And the float 13.6 is beneficial no? 13.6?
Im trying to find specs on other modules.
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 constantcurrent
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 480 minutes (8 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 480 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 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 initiates an equalization stage to remove sulfate layers from the battery
plates. In either situation, the unit exits the FLOAT STAGE and enters the BULK STAGE
