I'm looking to start building a battery bank since I bought a crescendo bc5500 recently and won't be able to use it for a while. So far all I have done is the big 3 in my vehicle with the stock alt and added two extra batteries. Some walmart battery a friend gave me and an xs power xp750. They power a Skar rp-75.4 and an audiopipe apdl2001d "2krms". I have two crescendo symphony sc-650 6.5" component sets and two sundown x15 v.2's in a custom box tuned to 32 hz. The goal is to eventually have a c1100.4 power two 6.5"s, three tweets, and one 8" fiberglassed in both front doors with three x15s walled off on the bc5500. I want to replace the stock battery and have at least 4 batteries in the back. Just not sure of which batteries to get. I was hoping to not have to spend upwards of 400$ per battery. I'm still a car audio newb so I went to the xspower website and typed 7500 watts in the audio calculator and it told me one d7500 and three xp2500s would be sufficient. Thoughts?? I'll post some pics / more info soon
Alright SMD, I think its time! I would first like to introduce myself. My name is Wood and Im 23. Everything i own and will be done (by myself unfortunately) will be from hard work and dedication and my loyalty to the car/ car audio scene. No hand outs!! I work 50hrs a week, own my own EVRYTHING (but sometime it feel like bills own me LOL ) so YES, It will be a slow, but very progressive build. I'm enrolling back in college this coming fall to be an electrical engineer with 6yrs prior service in the Air Force Reserve as an EE on the F-16. I am a car enthusiast and music FREAK!!

EDIT (10/23/17): SOLD
I bought a bank of 73Ah K2 Lithium two months ago. I couldn't find more than a single bank. Since then, I've sold my car and have decided to add 3 banks of lithium to my build, so I am buying all JY Power. I already have 2 banks of JY, so I'd like to sell this K2 bank to get a third JY.
The bank with the copper bars is the one for sale. I made the bus bars, and the neat thing about them is that you can configure the cells in any configuration, unlike the JY bars.
Here's a thread I created concerning internal resistance. These batteries measure 3.3milliohms. One JY bank I bought measures 3.3milliohm and the other 2.7milliohm. So these K2's are in good shape.
Here's another thread detailing a conversation I had with Cameron at K2 concerning the good health of these cells:
Talk about boosting your resting voltage! I had 395Ah of XS Power AGM installed in my car already. When I added the 73Ah cells, the system voltage rose to 13.3V and stayed there strongly. I ran these for about a week before I sold my second car and decided to go bigger.
Asking $700 shipped to the lower 48 with bus bars included. $650 delivered to (almost) anywhere in central/east Texas and Lousiana.
