Looks like another rebranding of the UPG battery to me, but who really knows if the internals are the same.
Look up the 8d UPG battery and compare specs.
Seems you like the paired UPG 27's you have.
Regarding the AGm and thin plates, I am close to the 800 deep cycle range on my Northstar and at least a hundred of those are below 50% SOC and many of those are down to as low as 25% SOC
But Northstar is no Budget thin plate battery.
If I take 45 of its 90AH original rating, at twice the 4.5 amp rate at which it earned its rating, the voltage still rebounds to well over 12.2v with loads removed, and it can still easily start my engine depleted 65 of its 90AH.
