PM D3100 from what I've heard
Hc 3800>>>>hc 2400
I dig the nsb90 and the d3100. Both are winners.
--My truck: 2007 GMC 1500 crew cab, Kenwood DNX570HD, DLS front stage, SQ3500.1, 3x RD Alpha Max 15"s in 6th order blow through, Second Skin deadening.
--Wife's car: 2013 Chevrolet Impala LTZ, Kenwood DNX470, GermanMAESTRO components on CT125.2, 2x AT10"s on an AT800.1, RF Deadskin deadening.
--Work truck: 2014 GMC 2500 crew cab, Kenwood DNX470, Kenwood front stage, DD M1A on a pair of American Bass XD10s.
After the tests, that I did today, I would say hands down the NSB G3100 is the strongest group 31 battery I've worked with to date. I have worked with just about every group 31 battery and below worth testing. Good luck!!

What are you considering powerful? One group 31 could have a high AH and another group 31 could have a high CA. You trade off between AH and CA by how thick the plates are. You can only fit so much lead in a group 31 batt.
