I may have missed it, but what's the charge current capability (Amps) of your charger?
As previously noted, your pack appears to be dead-flat according to the voltages you are seeing
If your clamp meter can do DC current, what are you seeing going into the battery??

Checked the volts it was 0.006

Ouch! Does a label on the charger tell you anything useful?

Something is very wrong here.
Can you post a photo of your charger? Maybe we can glean something useful from that.

OK 8A charger. "Should" be good for a full charge overnight.
What are the LEDs on the charger doing?
Can you measure the output of the charger with the battery disconnected, I have a similar unit which gives its full output voltage.

That's what's lights are on

10 volts ac

OkYou should be measuring DC, making an AC measurement is meaningless
It's 58.4

Great, if not already connected connect it to your battery and check again, DC volts at the battery.
Do the LEDs change when on the battery? Once you have volts on the battery terminals try turning on the BMS.

OK so oddly both lights stay on and it show 58 at the battery
As for the bms it's built in to the unit

So, the charger lights don't change? It thinks the pack is full or not connected.
What do the BMS lights say? Does it have a "reset" switch (maybe behind a small hole)?

No the lights don't change and I believe the way you reset it is to keep holding the sw botton

So it just went into protection mode and started beeping at me

So I just checked the battery ? and it's showing 44 volts
