Battery power for 7.5k

[josephj86]

Wondering how much battery power for 7.5k would be sufficient? Any help would be much appreciated thanks

Solid battery under the hood and 3 or 4 in the back. I have a group 31 under the hood and 2 smsagm220 in the back running a 6k mono and 1k 4 channel and stay in the mid to upper 13s

This with a HO Alt, Big 3. Could Go LTO or Supercapacitors to save on weight and size
