The battery being tested here is the Novae 32650 protected battery. Link here.
Battery true dimensions are 32.75mm diameter and 70.40mm length. Checked with dial calipers.
I tested this battery with the turnigy accucel 8150 at 3 amps cutoff at 3v. Now i know this is not the correct discharge current for finding the true capacity. But i intended to run this battery at close to that in a 1 D maglite with xm-l. So i wanted to know what the real world capacity would be for my application. So here's what i got at 3 amps.
The big D got almost 4700mah. With a run time of a little over 1 1/2 hours.
So if i was building a single cell light drawing 3 amps with the shiningbeam 7135 driver. I would have almost the same run time as running 2 quality 18650's with a buck driver. If i use 2 32650's in a 2D mag that would be over 3 hours with a buck driver. Some serious run time for a 2D mag. Tail cap will have to be modified to fit.
I checked to see if these 32650's would fit in a 2D mag. They will but you will have to remove some of the tail cap lip for the tail to screw all the way on. The battery will fit down inside where the spring rest. But it needs to go about 2 mm farther inside the cap. With a lathe this is no problem. A dremel tool will probably make quick work of this also. The spring will have to be real short.
When i tested the battery i occasionally touched the battery to see if it was building any heat. No heat what so ever. The battery stayed cool to the touch all the way through the test. My conclusion is that i like the batterys for mag builds. No more battery adapters for 18650's.
On a different note, i did order these from Novae and received one battery damaged. Emailed them about the problem and they were very apologetic and offered to send me a brand new one. Got it in the mail in about three days. Company handled the replacment very well without hassle.
