High Drain - this battery is made for high current (up to 10A) applications. With our 7A PCB this battery loses hardly any capacity on high discharge current
Standard charging current: 580mAh for 5.5 hours to 4.2 V
Maximum charge current 1450 mA
Protection circuit: 7 A - For Flashlights with over 20 Wh
Deep discharge protection: at 3V
Raised positive nipple - Button Top
Nickel base plate for added durability
Panasonic Cell - UL - certification
Diameter: 18 mm
Length: 69 mm
Weight: 48g +/- 1-2g
With our own welding innovation the button-top would be weld directly on the cell - lower internal resistance and more robustness.
CE certification
Assembly "Made in Germany"
This battery uses a new version of the Panasonic 2900 mAh cell designed for higher current.
The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity.
The voltage and capacity at higher current is slighty higher then the old 2900 mAh cell (Use my comperator to compare).
The two batteries I got does show a very good match.
Conclusion
The higher voltage at high currents is a nice improvement to the 2900 cell.
The battery gets a very good rating.
Great, thank you. Seems to be a pretty awesome battery. Performs almost as good as the 2250mAh "IMR" but has more capacity.
LG D1 is still superior tho..
In a German board, I read about the LG D1 and this improved Panasonic cells that these two have a more dangerous chemistry than normal LiIon cells. Not more unstable, but when something goes wrong, it might go wrong worse.
The NCR18650PD seems very affordable, and readily available.
The Enerpower+ 2900mAh 3C seems to be the only protected version on the market. I bought 1 to try a few months ago. It is a good cell. I find it best in my lights that pull upto about 3.75A, but the Panasonic CGR18650CH is better above that.
linergy shop charges 5€ extra for small orders. Also, according to HKJ tests, PD is superior to the CH up to about 7A. Protected PD vs unprotected CD are about equal at 5A.
From HKJ’s comparison charts, under initial load, the CH holds voltage better than the PD at all discharge currents, but the PD starts to hold voltage better as the cell starts to discharge.
But at 5A and above the CH holds voltage far higher initially, then matches the PD down to 3.2v, then the PD’s greater capacity shows.
One thing i have found though is that using a 4.5A light, the PD will give about 3.8-3.9A at the tail. The CH will give 4.25A.
This must be down to the lower internal resistance of the unprotected CH cell.
These are great cells Kreisler. I ran my Enerpower+ 2900mAh/3C in a direct drive XM-L u3 that i put together today using an Led-Tech copper star. I measured 7A @ the tail.
I then got curious and tried a Samsung INR18650-20R, and measured 9.5A at the tail for about 2 seconds, then fried the Led :cry:
There is none available. But you can take the one from the NCR18650 as reference. There is a lot of info about that cell spread around the internet, so if you have any specific question, just ask. ;)
