So I unfortunately I let my energica get down to 0% but the bike still turns on. It straight up doesn't charge on level 1 or level 2 charging. When I charge on level 3 it works but after charging up to about 30% it eventually stops itself and complains about a fault. The crazy thing is that after I turn the bike back on, I watch the dash change from 30% back to 0% almost immediately. I tried this twice and it happens both times.
Any help or insight would be very much appreciated.
My hope is that this would be covered by warranty when they go back into business and they can fix this issue but if there is anything else I can do I rather not wait.

For how long was it left at 0% SOC?
-
A good while, probably 2 months. I thought it was gonna be able to hold it's charge longer.

Can you enter the engineering Menu for us?
Could be that your battery is depleted, with possible internal cell damage. The bikes don't have a 12V battery, they have a DC/DC converter that is permanently on and "nibbles" on the battery pack the whole time.
Also it's stated in the bikes manual that the bike is to be charged immediately at low SoCs (within 24 hrs)....for that exact reason

that sounds like you cooked a cell or a few.
The engineering menu, look at min / max cell volt and let us know what it says, also the pack voltage. Try to do an ac charge at home, record cell voltage at beginning and right after it starts. Walk it down to like 2 amps let it charge, get the numbers, bump to 5 amp, then 10 then whatever it can take, recording the pack voltage and cell hi / low. This will help show if you cooked a cell (s) or not in your pack.
Unfortunately you might have done just that.
When the battery goes to zero, others around it may still have a little juice in them, and if you keep pushing, will drive it well.. below zero basically, until the internal resistance gets so high, it's basically a brick at that point and now is irreparably damaged. You may be able to charge it a little bit, but it's been destroyed, and can only hold like 10 percent of it's charge, and pushing anymore causes it's volts to skyrocket, tripping out the cell / causing a fault.
The absolute worst thing you can ever do with lithium cells is to store them at zero, or at full charge, topping them off and letting them sit, stewing at that high soc can really throw a wrench into them as well.
You said you got some charge into it? Will the bike run at all? There is a chance if it does, you may be able to 'walk it off'. Run it down slow charge, down, charge cycle it 5 or 6 times and it might bring some of that battery's capacity back to life. This is a hail mary though and don't hold your breath too long on it, but worth a try before throwing in the towel.
if you can get it to take a charge, do so very slowly, on AC put 3 to 4 amps into it, yes i know it's slow, but you are trying to nurse it back to health, and pushing it hard won't be helpful.
Good luck.

Probably permanent damage to the battery. When it is 100% discharged, it needs to be recharged within hours.
Good luck, but you probably will need a new battery.

When you say it won't charge at lev 1 or 2 what exactly does it do? Do what Arron says, set max charge rate to maybe 4-5 amps and keep trying it may take 7-8 cycles.
