Iota IQ new module algorithms.

[lawrosa]

Had call into iota to get parameters on the IQ modules. The typical IQ4 parameters are listed on their web site here.

Iq4
Bulk 14.8 - 4 hours or trigger 14.6 ,
absorb 14.2 - 8 hours,
13.6 float

So theys have several new modules and curiosity got me. They sent me PDF's as they are not on the web site..

Ill do the IQ turbo first to see if viewers can see the documant. I had to copy from PDF... PITA ill tell ya.....

IQ turbo

Looks like just a higher absorb but less time...

Bulk 14.78 - 4 hours or trigger 14.6 ,
absorb 14.51 - 2 hours,
13.6 float

For my Megawatts in an off-grid environment. I try to time the 1st stage to remain at 14.8 volts for 2 hours after attaining 14.8 volts. By choosing a 4,6,8 or 12 hour timer the charging time is set in proportion to ampere hours. One group 24 gets the 4-hour intermatic while 4 golf car batteries get the 12 hour windup. Too much gen run time!

The "secret" is to find out WHEN the batteries start to bubble THEN establish gen surplus run time needed to revert the electrolyte.

From 12.13 volts by saturation charging I can half percent the 31 XT in 2 hours 16 minutes.

BFL I tried to PM you... says not allowed...

Nice, an equilizer mode for my iota !!
And probly get the turbo for when using the generator!!
Tanks for the info

I cant verify. It does say up to 8 hours... Which may mean can there be an amp trigger of some sort? Like if it senses 17 amps it will go to float?

The Wfco's advertised that I believe.

Good question, since their blurb seems to say 8 hours no matter what.

Don't know, but IMO it wouldn't hurt anything if it stayed at 14.2 for a while after amps tapered down to where normally a three-stager would drop to 13.6. (at about 97% SOC AFAIK)

ISTR the PD will stay at 14.4 until amps taper right down and then drop to 13.6, even if that only takes three hours, but if you kick it into 14.4 with the CW it stays there the full four hours no matter what, and then drops even if amps are not down there yet? (so hit the boost for another four)

The DC24's I have state 14.4-14.7 Charge until change in current < 0.10A per Hr / Max Time: 12Hr

Float charges get me and there does not to be anything out there with high floats. This is deka parameters.
Float 13.80V - 14.10V

So you kill the batteries a slow death?

This includes the deka golf cart 6 er's

Depends on the battery manufacturer; could be up to 24 hours.
My Exide Stowaways are 12 to 24 hours at 14.7 to 14.9 volts @ 77 deg F.

The AGM one would work for mine. They want 14.8ish until the amps acceptance is down to near zip and then Float at 13.6ish. Lifeline AGMs want that lower voltage 14.4

That 14.8 happens to also be what my 6s want, so that IQ AGM model would be the one to get if going Iota. The other one that changed up Vabs to 14.5 from 14.2 is sort of useless for anything I do.

Equalize in the 15s? What good is that?--Trojan wants 16.2, which Iota must know about.

I prefer the manually adjustable voltage charger that can meet any battery specs at the turn of a knob.

Options are always nice.

I was annoyed when none of their voltage specs were listed on their site so thanks for going through the effort.

I'll stick with manual voltage control for my myself,
but will consider some of these for installs in other rigs. I've chosen the PD9245 twice so far just for the manual override, but explaining the purpose of this feature to the owners usually causes confusion, and they seem to sigh with relief when i say they do not have to push any buttons, it is automatic with the option of manual override.

removing the button option could be good for some of them

And here is the very interesting one...

IQagm

Iq4
Bulk 14.7 - 8 hours no trigger
absorb none
13.6 float 7 days

Low triggers state 12.8 on the units that will go back into bulk...

[lawrosa]

Iq equalize
Bulk 15.41 - 2 hours no trigger
absorb None
13.6 float ( 109 days. To initiate bulk just unplugged module and plug back in.)

Interesting!!!!!
