Spare cable for Lifeline Ara/Pavo lights?

Hi all,

I have the Lifeline Ara ( https://www.bikeradar.com/reviews/accessories/lights/front-light/lifeline-ara-2000l-front-light-review) light that I picked up in the final CRC sale.

The cable on the light itself is only ~8cm, and then there is a ~15cm extension lead that goes between the light cable and the btatery.

I'd love to get a longer extension lead, but struggling to find one (very aware that this is why you don't buy a budget own-brand item from a store about to go under...). This is a pic of the extension lead:

Does anyone know if this is a standard connector, and if so what it's called?

(If anyone happens to have one, or a spare battery, please shout!)

Thanks,

Duane
