With a maximum continuous current at 3.5 amp and 6 amp pulse rating it's not for Mech's
The Panasonic NCR18650B has a 3400 mAh rating and has better spec. It's about $9 dollars per cell. Still not recommended for mech's

What's the amp limit on the Panasonic's? Are they the green ones?

What's the amp limit on the Panasonic's? Are they the green ones?

Model: NCR18650B (Green)
I DO NOT recommend these cells for mech mods.
This is a awesome cell for regulated mods with a amp limit of 5 amps. (Vamo, SVD, ECT)

• Charging Voltage (V): 4.2 V

• Energy (Wh): 12.2 Wh

• Energy Density (Wh/L): 730 Wh/L

• Nominal Voltage (V): 3.6V-3.7V

• Weight (g): 46 g

• Diameter (mm): 18.06 mm (+/- 0.03 mm)

• Height (mm): 65 mm (+/- 0.03 mm)

• Max. Discharge rate: 2C (6.8A)

• Pulse current (5-6 sec.): 12A

• Top (positive side): Flat top

• Made in Japan

• Made by Panasonic

You claim they match up to a sony. Here are the specs on the Voidhawk from their site and below are the sony specs. They aren't even in the same ball park when it comes to being close close.

My brain always hurts...

 

[derichio02]

Wow so this whole thread turns to me?!?! All I did was ask a question about info that was already posted here. I know what to use in my mods and I never asked about using this battery. I had just previously read a thread where they were asking whether it was 1C or 2C. I didn't say anything g about using them. And Celtic you are pointing out my post why? You yourself asked about a wack battery that you then compared to Sony. I guess your redirecting people calling you out to me. Lol its cool I can take it but don't put words in my mouth

Thanks

Misread then. Apologies for misunderstanding. Thanks for the post and the message! Sorry I jumped the gun

Like i said, higher mah rating, lower continuous current output, higher voltage, same charge voltage same full charge voltage, the only thing different, is the lower continuous amp output....Free 25 dollar batteries to try....obviously you will pass I assume....Exactly what I said....Free batteries for those willing to do a review....I know your in love with sony, but I dont have any to offer for trial.

I not a fan boy for any one battery. I own several different brands. (Panasonic, AW, Orbtronics, Sony, Efest, MNKE, Sanyo, LG) Each one for a applied purpose. I have seen a lot of cells make claims that aren't even close to true. That could get a person injured.
I'm not knocking the Voidhawk. The only thing I know about it is what the manufacturer specs tell about it. That was enough for me to jump in and make aware those that don't understand battery limits or chemistry. People can get hurt when using a high power battery cells improperly. I just want you to understand the battery better before you start selling them. When you compare the Voidhawk to the Sony and say they are on par. That statement isn't right. The only thing they have in common is the max charge. The max charge on most 18650 Li. Lm. batteries is 4.2 volts with the exception of a couple that are 4.35 The most important things to look at in a battery are, Is it protected or not, amp limit, chemistry, and mAh capacity. Just because a batteries Mah rating is high doesn't make it a better cell. Although most people think it does.

Thats a protected flashlight battery. I wouldnt use it in any mod unless its a older OKR or TI VV box where you stack matched batteries and the chip steps down the voltage(those who own or have owned one knows what it is). This is essentially a high mah trustfire flame type battery. The chemistry on these is also the kind that blows up if the pcb protection on the battery fails.

That being said these would work great in a cree led flashlight.

The OP didn't want to hear the truth about the battery. He just sent me a nasty PM. What a tool. All I did was try to educate him a little. Wait until he posts this battery on another site. I hope the OP has a flame suite.
