[QUOTE="mat3833, post: 8825890, member: 587645"] Good info here. Only issue is you didn't take into account amp efficiency, and listed 14.4v to get your amps. Kinda nitpicking but still important. Proper math should be somewhere around 85 percent efficiency for a class D, and 13.5v for lithium battery or 13v for AGM. You can use 12v as a bottom line worst case. 2200x1.2= 2640 2640/13.5=195. You can also just add 20 percent to your final number to take into account efficiency. 152x1.2=182.4a at 14.4v Otherwise, great info! Matt [/QUOTE]
