Running it on my 21 f150 5.0

The guys with XS power are outstanding. From tech support to customer service, they were knowledgeable and friendly. I ordered the RSV-46 for my f150s main battery because I already had 8 of their Titan 8 pwr-s5 lithium for battery bank but have the factory Alternator (I couldn't find a HO Alternator for a 23 f150 5.0) they sent me to Singer who assisted me with the Alternator situation. I received the battery in 2 or 3 days and went to install it. Everything was good but because of my fuse distribution and 1/0 wires, they would have it the roof and I didn't want to take a chance so back on the phone with the guys at XS. They had a battery hold down that didn't cross over the battery. The HD-34BS Hold Down Base to be exact. I wasn't sure if it would work and wanted to verify the thickness as the measurements dont give that information. He went and grabbed one to get me that info. After that, knowing I was stuck he was able to get it out that day and I received it in 2 days as well!
I cannot praise them enough for how well they treat me. Thank you again guys!

Nice Lithium battery, the only downside (for my setup) is it works so good my mechman alternator will only charge at 13.8V all the time because my vehicle's PCM see's the battery as full as it never drops voltage even under heavy bass notes.
