Hey all,

My gbz was crashing and why I found out what is was I crossed the power and ground wires while the power was on, now my GBZ wont start.
Did I kill my battery?

You might have killed the whole system. Test if the Pi even turns on by plugging it to a micro use on the OTG port.

If you're lucky, the battery is protected, and has just disconnected itself.

Try testing as helder suggested, if all is well then check the battery for any bulges. If the battery seems ok try plugging in the charger for a few seconds then see if you have life again.

If it's a protected battery, charging will reset the protection circuit and reconnect the power.

I was lucky, only the audio amp fried.

The battery is fully intact, no bubbles or something, for some reason it did fully drain itself.
But after charging nothing seems wrong.
