Battery light started turning on out of the blue.

[Jonnyswboy]

I've had my system the same for a while and recently when I push it to its limit the battery light will come on and stay on until I turn the car off and back on. I've never seen my voltage dip under ~13.3v when I'm pushing it so I'm not sure what the cause is. Even if it went into the low 12s I wouldn't expect the light to turn on.

Any ideas? Battery rests at ~14.2v so it's not a bad battery.

Battery rests at ~14.2v

Is this with the car off? I have never seen that high of a resting voltage.

What battery(s) do you have?
Regular lead acid usyally rests in the low 12s.

It is 14.2v with the car off. It's because I'm running an 80AH bank of Yinlong Lithium. It's normal. But I never used to have the battery light come on.
