E7YCT Battery Extender for E7

Absolutely love the flashlight and the battery extender! I use this everyday for work .. the battery life is excellent... I would recommend this to anyone needing a quality flashlight . I'll be purchasing another soon .

extender fits well, I like the longer barrel and battery life

Really really like it thanks. Would be nice if it had a red light on it so a person could use it in a no lite area

Well... I'm a dummy, as I didn't realize I had to purchase the bigger battery as well. I was going to purchase it once I realized my mistake, but can't. General principal conflict. I need to 2 batteries for the 2 extenders I purchased, for the 2 e7's I purchased. Problem is, I buy 2 batteries at @ $18 each, and end up paying roughly the same cost in shipping. I just can't. And won't. Can't afford and can't justify. So, while it's my fault I didn't realize the specifics, I can't justify paying the cost of 3 batteries, for 2. So... I can't tell you how they work, and doubt anything's goinna change, and it's likely too late to send them back. If I find a similar sized battery that's reliable, I'll let you know how they work. Otherwise... The headlamps work well, but like so many other products these days, the battery life could better. Quite the ridiculous conundrum I've put myself in.

Excellent quality and perfect item to extend battery life.

Best EDC light I’ve ever had. Extremely bright.
