No
Running it down can actually damage the battery and implement safety features that will prevent a charge.
Test your charger with a voltage meter to be sure it is putting out voltage.

The charger is putting out i may have damaged battery by running two low,but it did recharge to 48%after the low discharge

The BMS "should" have protected it from discharging too low.
Can you test the battery voltage directly from the battery?

Thanks for the replies, I took the battery and bike to the shop that I purchased it from, for me I feel better letting them look at it,I trust your help, but not my labor, I'll let you know what they say.
