I will be doing a battery comparison test with my termlab magnum, most likely when I get some time over spring break next month. I'm open to test more if you send them to me as long as I don't get overloaded with like 20 batteries to test.
We will be comparing the SMS series with the standard engine starting NorthStar batteries to see if they live up the the hype.
1. NSB G31
2. 2 NSB G31
3. 2 NSB G34
4. NSB SMS220
5. NSB SMS400
6. NSB SMS480
Just for fun I may or may not add these two, we will see:
1. Odyssey Extreme 31
2. Odyssey Performance 31
I'd like to test a lithium as well, but I don't personally have one. The smaller JY or XS15k would be preferred but any of them would work.
Measurements taken:
Voltage
Amperage draw
Clamped power output of amp(s)
SPL score
