Don't use a LiOn battery.  Get a regular acid battery if you can.  Unless you've upgraded the charging system to something that is compatible with LiOn it will not work right.  Same problem with AGM batteries.  Really, anything that is not the standard acid battery.

^This. In general stick to the original components. They won't let you down. Don't chase fantasies and ride more! ;)

Well yea apparently my ricks RR isn’t compatible with lithium ion batteries, guess I learned something new there. So lead acid battery is good to get?

I’m not able to upload a picture because my file is too large from my phone, but if it helps describing it I have a tray under the seat and I just put all the wiring in there and the battery was sitting on the sway bar

I feel like an idiot, got a new lead acid battery and she fired right up *facepalms* now I have to figure out why my running tails don’t work and she’ll be 100% any suggestions?

What do you mean by "sway bar"?? Did the battery terminals get shorted to each other?
With the bike running, measure the voltage across the battery terminals.

Voltages good, i locates the battery to sit on the sway bar with a block off plate “mud guard” but the only issue I have now is my running tails not working ever since I fried the charging system

There's riding and riding. If you've been using your bike like a moped and have not been ridng it @ over 3500 rpm long enough, the battery may deplete. Realise that the headlamp-always-on-arrangement (even before starting) doesn't help much. If you have a multimeter, reading the charging is dead simple.

Upon fixing it first day I rode it an accumulative of a little over 100 miles then 50 miles the next day full throttle on highway and it’s a brand new battery

My head hurts because you won't give me a straight answer to any question I've asked. >:( What was the voltage across the battery terminals with the motor running? "Voltages good" is Not an acceptable answer.

And according to two tired in a different thread he said “   However, if at any time the battery voltage rises above 15V, stop the test.  Such an indication would prove the charging system capable of maintaining a known good battery.  If this test never achieves 15V, then there is a wire/connector issue in either the ground path leading back to the battery ” so I was under the impression my charging system is fine

15v in a lithium battery will set it on fire, 15v on a wet battery will boil the acid out. Mounting a battery on a moving part is, in my opinion, so dangerous than i would refuse, as a certified engineer, to certify it.
