To buck voltage from 12 volts and change to 8.00 volts takes a BUCKING DC to DC converter. Voltage adjustable

It would need a second potentiometer on the board to set AMPERAGE cutout. In the case of a GC that would be an amperage setting of 11.0 on the amperage potentiometer to agree with 220 ampere hours capacity.
You can see the second pot on the 600 watt booster gizmo.
Thanks Mex... Yeah, I had the cc and cv stuff figured out. I was trying to figure out if there was a unit that would serve everybody's needs, but it looks like it would be best to just use a buck-a-roo on 6's, and a booster on 12's.
But either way, a nice affordable option for folks who are happy with their current converter and/or charger, but need something to EQ.
Tomorrow I'm EQ'ing two of my 6's with the cps1620. Used it to top charge today... works great! And it's nice to actually understand what it's doing! - jrnymn7Explorer"but the output voltage can not be lower than the input voltage."
yes, to use the boost converters one would have to supply them with a 6v / 12a 60w power supply like this one:
http://www.ebay.ca/itm/Universal-5-12-24-48V-1-2-3-10-15-20-30-50A-Switch-Power-Supply
So probably better to just go with a BUCK converter for 6v batts, and a boost for 12v batts.
And should be cc and cv either way. - jrnymn7Explorer

Thanks for the explanation, MEX!
So, would the DROK 200W/12A DC Buck Converter Constant Current/Voltage Regulator 4.5-30V to DC 0.8-28V unit I posted work with individual 3 cell 6v GC2's, or does it only BUCK (step-down) voltage?

Sorry, I meant to ask if this unit would work with BOTH 6v and 12v batts? I'm thinking no, seeing as others are clearly labelled as buck/boost.
I EDITED the other post to ask if it would work with 12v batts as well? - MrWizardModeratorthe 400 watt one matches the ebay 400w
all three look to be the same thing, sold by three different sellers
only the first one by DROK has the sticker removed from the side
none of them say BUCK..they all say boost
only the ebay seller actually spells it out in the spec list
according to the ebay seller boost only , No buck
red highlight is mine
Advanced microprocessor,
Use button precisely regulated output voltage, current
4 bit high brightness LED, real-time display output voltage, current , you can manually switch shown , can also be set auto rotate
Specification:
Input voltage : 6V -40V
Input Current: 15A(max)
Output voltage : 8V -80V(adjustable)
Output power:400W(max)
Output current: maximum output current of 10A ( adjustable )
Output power: the effective power P = input voltage V * 10A
Conversion efficiency: up to 95% ( input voltage, current; output voltage and current impact of conversion efficiency )
Short circuit protection : Fuse
Size :85*75*64mm
Weight :295g
Applications:
1.DIY an output adjustable power supply, only need to enter the access 6v,12V.24v .36v power supply or battery can be (14V-80V) free continuous adjustment,
but the output voltage can not be lower than the input voltage.
2 universal car laptop power supply. Input connected to 12V power supply, the output voltage can be adjusted to the notebook need work.
3.Boost charger with 12V power supply is higher than 12V battery charging, for example, 24V battery and charging current can be adjusted.
4.For electronic equipment power supply, as long as the voltage regulator to the required voltage and current does not exceed the rated current is normal.

For 6v GC2's, these two would have to be set at their absolute minimum output voltage setting:
