I have been looking at several XS batteries and I am seeing some numbers that confuse me. Can you educate me on this? All information was taken from SonicElectronix.com
XP750
AH=22
CA=750
$99.99
D375
AH=15
CA=190
$109.99
D545
AH=14
CA=240
$119.99
If all of them are rated for systems of 600 watts, why do the two batteries with the smaller specs cost more? Are there specific differences? If so, what are they?
