    battery and extension cable question

    I have a dinotte xml-3 v1. I was wondering if anyone can tell me if the battery will drain if I leave the extension cable attached. I was out for a ride tonight with what I thought was a near full charge on my battery. I had to cut my ride a little short when after about 15 minutes in the light flashed indicating a low battery. I was puzzled, but I remembered leaving the battery in my camelbak with the extension cable attached. Could that be the cause? Luckily, I started in daylight and had over an hour already logged.
    Get out and ride even when you don't want to because ten minutes into the ride you'll be glad you did.

    All lights will draw small current from battery when connected. If your light has constantly-lit battery indicator (like most chinese lights) then that current draw can be high enough to slowly discharge the battery (it will take a few days, maybe weeks - but battery will be discharged).

    If the cable is attached to the battery and nothing is attached to that - then no. If the light is attached then likely yes.
