The cost difference is basically a wash when you look at the quality NI-mh cells -http://www.batteryspace.com/Custom-NiMH ... erson.aspx

All batteries have a finite life cycle. A well cared for lithium pack will last just as long as a Ni-mh pack.

i been doing some reading on lithium battery packs they need a battery protection circuit that prevents you from over-discharging the battery. Over-discharging will damage the battery and render it use the first time you do it and most lithium battery pack don’t have this circuit on the battery pack this normally on the device you plug it into

not to mention that short circuiting them can cause them to explode and they need special charger
All true. If you dig around on the link I posted above, you can buy chargers as well as protection circuits for various battery types. These are the same protection circuits that at least one major light manufacturer uses in their lights. Lithium batteries do require some extra caution and care, but it's not all that big of an issue. Your laptop is full of them.
Frankly, after my recent research I think all the fuss about lithium batteries is vastly over done. If you buy a device use it. If you build a battery pack put a protective circuit in it. There are millions, if not billions, of lithium batteries in use in a wide variety of devices with no problems. It is a waste of precious cerebral cells to worry about them.
The only box you have to think outside of is the one you build around yourself.

My lithium packs all have protection circuits. Any high-amp battery can combust if shorted, and every battery type requires a special charger for that type and pack arrangement.

Dang Dusty!!!!

Post by coach_izzy »

I took my new "Dusty" light for a dive on Monday. All I can say is:

"Dang, man!"

The light exceeded my expectations and I could not be happier. Bob "Grateful Diver" Bailey was impressed with the output and I'm sure he's seen many lights in his diving career. I'm amazed at how much better my trim feels with this light, now replacing my formerly dangling UK Light Cannon.

Thank you, Rich, for putting together such an awesome light at such an amazing price. What a bargain!

Good thing I caught this thread!

Best!

I would buy a light from you again with absolutely no hesitation. Make great lights and customer service far exceeds expectations. :notworthy:

No doubt about it! That's a lot of bang for the buck you are putting there and divers know how to snag a good deal. If you don't have an Ebay store or Craig's List ad, you should.

Thank you again for putting out such an awesome product. It's always a pleasure doing business with an honest and hard working entrepreneur. :supz:
