I think its a good price.

But I dont understant, someone said that Samsungs charge to 4,35V??

Can someone more knowledgable explain?

I can’t explain it, but it is written in the Samsung homepage, that the Samsung 3000mAh 30A needs 4,35V to be full.
The Samsung 2800mAh needs 4,3V.

Can this be dangerous for lights that are specified for 4,2V? Or it snot a problem, just 0,1-0,15V difference?

Not a problem for the most part. However, unless you get a special charge for them (or have a hobby charger) then they are not going to reach that voltage.

This are only 4% more and I don’t think, that this will harmful (in a single 18650 flashlight). But I would not try to use 2-3 of them in a flashlight in serial.

This depends on the actual cell/battery, in my battery review I do test cells/batteries that need higher voltage, both at the high voltage and at 4.2 volt. You are not required to use the higher voltage, but will get less capacity when using the 4.2 volt on a 4.3 or 4.35 volt cell. To see how much you loose, check my reviews.

Thanx

Cottonpickers sells a VERY nice charger that can do the 4.35v batteries to full capacity! They work REALLY well :slight_smile:

My Hi-Max 18650 needs to be rotated until the ‘sweet spot’ is found to fit in the UF T50 and then it slides right in, albeit quite snugly. It’s a slight nuisance but manageable. However, if there is going to be trouble with them fitting at all in some lights then it’s a pretty big issue, imo.

Try rotating it as you let gravity (and maybe just a little bit pressure) force it down. It’s the positive end (PCB) that hangs up so once you get past that there shouldn’t be any more issue. That’s the case with mine anyway.

I had to cut the outer clear layer off mine to fit into my UltraFire 2100 and do not see any problem with doing that

I dont know why tere’s not group buy for these here on the forum.
I bought 12pcs (2600mAh) from ebay (from that pingyi seller, something like that) for 59$ with shipment. Thats 5,25$ per cell, great price, and these cells are way better than 2400 TF flames.

Are these the way to go as a step up from Trustfire Flames?

There seems to be so many brands and deals around that I can’t keep up; I realise there are better batteries out there but these seem to be well thought of for the price. Would they be a better buy than the Tank007s from here?

With the known reputation of the HiMax why consider some new unknown brand?

Well, as someone who’s fairly new to the flashlight scene, the Tank007 cells are an unknown quantity; they may be better or worse than the HiMax and I was hoping someone with greater knowledge than myself could advise me on these and other cells.

Sometimes the best option isn’t always the one directly in front of you! :wink:

These cells are made by Samsung.

HKJ’s review of this one is indispensable :stuck_out_tongue: 8)

Looks like HiMax are the way to go then! :bigsmile:

Wait, HiMax cells are made by Samsung?

You will get it soon, I have the test data ready

Yep. I was told that by Shane who sells them. He ought to know since he buys them.
