The Survival Laser battery extension tube (P/N SL-BET1) is now available for sale on the Survival Laser webstore.

The battery extension tube allows the use of two "18650" Li-ion batteries with the Survival Laser for higher battery capacity, longer total run times and at full output power. This tube can also be used in other Aurora C6-style lasers that normally use two CR123A or RCR123A batteries, including Yobresal's 1-1.2W 445nm builds.

However, DO NOT use this battery extension tube with laser builds that include a "boost" driver circuit that is limited to a maximum input voltage of 5.5-6V, as you will likely damage or destroy the driver.

The tube is black anodized aluminum with bare threads for good electrical conductivity. Note: Laser and batteries not included. :crackup:

Wouldn't that just cause the driver to generate more heat from the extra voltage, thus not really increasing run time at all?

If the host is already using two 3.7V CR123A's batteries to two 3.7V 18650's there is not difference in voltage. He did say this is not for Boost drives that are already just using one 18650.

Nope.:) The Driver runs on 2x 3.7v 16340/Cr123A cells witch is 8.4v fully charged with out the tube to power a 445nm diode. This is the best voltage to run this driver at.

So running it with the tube will allow you to use 2x 18650 cells and achieve 8.4v with a much much longer run time over using 2x 16340/Cr123A cells.

The survival laser kits seem to always run on 2x 16340 (not boost drivers). So this really would double the available battery capacity, with the same supplied voltage.

I think his point was more geared towards that people who've bought SL heatsinks for the Aurora DIY host, and are using their own boost driver solutions (instead of the non-boost driver solutions they sell).

I see. I thought that CR123's only came in 3 volts.

Good lord almost $30 for that, I would love to get one but I cant justify a $30 extension tube. Im sure you had to find someone to make em since DX doesnt have any, maybe one day if I have some extra money burning a hole in my pocket.

I forget how that host unscrews, but it seems like you could almost justify just buying a second C6 DIY kit from DX for $12, and use that if it worked.

Well if you ask nice I might give you an LPF discount. ;)

Yes, they were custom made in the US in a relatively small quantity. Plus we had to price them so that our dealers could carry them too.

That would not work.
This looks like a great addition to your kit!
Thanks for making this available.

Nope, that won't work. I also went to the manufacturer to ask if they had such a tube for the host and the answer was no. I wasn't about to invest a pile of cash into a part that could be purchased off the shelf for less.

Well in that case I might have to order one in a few weeks. Also I noticed that unitednuclear was carrying your lasers which is badass, I love that site.

Sorry to say this but I find it quite expensive for what it is. This is just a personal opinion though. No intense to threadjack. Mind explaining why it's a bit costy?

If you scroll up the thread a little bit you will see that I already explained the pricing. People always have an opportunity to purchase a lower cost alternative. ;)
