Ballistic Lithium Battery Dead

So last week the battery got drained from my sound system on the bike, don't ask me how LOL.
Anyways, we had to boost the battery and got it up and running. 2 days ago the bike was bogging or something and the lights started to flicker, I bought a voltmeter and it read 12v idle.
Just a while ago, the bike just turned off and died, no power at all.

So my question is, did I screw up the rectifier? Stator? or the Battery since it was drained?
 
Did you just boost the battery and continue riding? or did you actually throw it on a charger and charge it back to 100%?

After charging the battery back to 100%, i would look at getting a multi meter and reading what it is at idle/startup/under load.
 
Probably battery. The problem with that type of battery chemistry is that if the state of charge drops below a certain critical level, it will "brick" - no longer capable of being recharged. (don't ask how I know this LOL)

Put the battery on a charger for a couple hours - use an old "dumb" charger - and see what happens. If the battery accepts the charge and starts the engine, measure the charging voltage with the engine above idle speed. It should be 13-something if the battery is drawing in current and has a low charge level - but eventually it must stabilize at least 14.4 volts in order to fully charge that type of battery. If the bike has a weak voltage regulator that won't deliver at least 14.4 volts, that style of battery will not charge properly.

If the voltage across the battery terminals is no higher with the engine running than it is with the engine switched off ... your charging system isn't. At that point, you will have to delve into it further, to establish that there are not any blown fuses, plugs disconnected, ground straps not secured, etc., and if all that is good, establish whether the regulator has good AC power on the input side.

Wiring is all good and there is good AC power on the input side but no DC output (or not enough) - Regulator is done.
Wiring is all good and AC supply to the regulator is faulty - Stator is done.
