14.4 volts to lights when charging?

when you are charging your batteries and charger is putting out 14.4 volts in boost mode, is that voltage going to harm led lights??

  • I suggest that if you will have shore power to get regulated lEDs. Short term higher voltage of charging wont cause the LEDs to pop instantly but may show long term effects. It can cause the imitation 3M tape to dislodge due to higher temps.
    As a boondocker our ebay LEDs never see higher voltages because we use the lights at night and charge during the day via solar or generator.
  • Yes, the 2 I bought from China for 10 bucks total a few yrs ago, lasted about a months time camping before over 1/2 the leds were burned out or blinking.
  • Some inexpensive LEDs do not have any voltage regulation and may be drawing more than their rated current (which could shorten life).

    Or, they may be set to run on 14.4 which means they won't be as bright at 12v.

    Better LEDs have voltage regulation so it doesn't make as much difference.
