Xs power Titan 8

[Jopipe17]

I was looking to change my stock battery for a XS Titan 8 s5 pwr4900 lithium. I was jus curious if it will be ok under the hood, I seen it says underhood safe but heard a couple people saying it's not safe and the heat will destroy the battery iver time. I figured I could get the 1 Titan 8 4900 lithium and be able to power my truck along with my 2.5k audio system. My other option was to get a xs d series 4900 agm and a d4s LTO 6.0 lithium for my 2nd battery in the back by my amp. You guys think the 1 lithium would be ok, or the agm and little D4S LTO lithium is better option? Thanks alot guys
