E7YCT Battery Extender for E7

Comodo, piccolo, con l'estensione la durata è molto lunga e il laccetto per la testa è perfetto per fare qualsiasi lavoro. Ottimo acquisto. Un po' lenta la consegna.

this should be bought with the E7 to extend run times with 18650 btteries

The E7 is a small, powerful light that punches well above its weight class. The light gets super bright but has 3 settings. I ordered the larger battery but it hasn’t come yet. It fits great in the head strap and it very adjustable.

Perfect add on for the head lamp, I can use it for hours while I’m working

I really don't know if it works because I somehow only ordered a tube for extending battery life without a battery. So its sitting on my desk like a nice shiny paperweight. Eventually I will get down to figuring out which battery to use and my E7 headband light will be even more useful at super bright setting for longer duration. It would be more convenient when ordering the bundle to include a battery option for purchase. Either way this will probably be useful product to buy if you like out doors and super bright light being used with greater duration.

Useful for accommodating the larger 18650 batteries. Wish I could order the wuben batteries for delivery in UK, trust them over other suppliers
