Those will be fine. It'd be a good idea to pull out the dropping from the second one and pack it with foil so it is an extremely tight fit in the head. The P60 dropping format was originally designed to keep the heat in the bulb which is fine but is the opposite of what you want with an LED. budgetlightforum.com/node/1403#comment-21791 will give some guidance on how to do it. |

I've got a couple of 18650 torches on order from FT so I'm trying these out, at £3 each it's worth a gamble Most torches - even the XM-l and XM-L2s don't draw more than 4A. Those cells should be fine for that. Which lights did you get? I own rather a lot of torches. |

My guess - the iJoy cells are not particularly high current rated. I'd not want to suck more than 4-5A out of them without knowing more about them. They will be ICR chemistry which means using them is not a good idea - I'll only use IMR cells in anything capable of more than 15W.

Some more instant custard. Some for me, some that just got posted.

In general chemical reactions (Which is what is happening as juice steeps) double in rate for every ten degrees increase in temperature. Too high a temperature and unwanted reactions may start, too low and the desired reactions will take way longer.

Those 18650s are not 20A cells, they are 6A cells and are probably not suited to vaping in a device capable of 50W. The 30A (VTC4 rewrap) or 35A (Which are actually 20A cells) ones would be OK though.

228 grams without an atomiser but with two Samsung 25R cells in it.

The higher the voltage you stop using and charge the cell at the better. I've discharged LG HE2s and Samsung 25Rs to below 2.4V. I do not recommend trying this though. Both of those are 2500mAh cells and hold their voltage under discharge better than Sony cells. Personally I prefer to charge at 3.6V but anything above 3V will be fine. I own a lot of 25R cells and use them most of the time.
Sony 'VTC4 cells tend to stop firing the atty by 3V.
I find I don't notice the drop off till the atty refuses to fire.
Most people do notice though.

I only ever dilute with VG so I start at 20%. The triple strength strawberry in a mix I use at 2%

If I want to go that low in power I'd use my Vamo

Don't want one. I've never been that low in power for 6 months

I only vape high VG mixes - I find they need more flavouring than mixes with more PG in them - Often over 20% flavouring.

Looks to be relatively straightforward to fix for someone who's better with a soldering iron than I am.

Try Cell data. These are all the cells that three of us have tested. IR is a lot higher for the VTC4 than I measure on my well used 10 I get mean of 12.1 m?, I will give you the Internal Resistances I have measured: 4 well used Panasonic NCR18650B I get mean of 43.25 m? 10 well used Panasonic CGR1865CH I get mean of 29.9 m? 2 (only half dozen cycles) Xtar 18500 both 19 m? 2 lightly used Efest red 18500 BT mean of 31 m? 9 Efest red 18350 are all over the place, both in IR and capacity All measured on a ZB206 analyser & I try to test around 4 V, but some IRs will be a bit high as I have only had the analyser for a month and some readings are when fully charged so probably too high. E: all the batteries were button top Yes - I have my doubts about the reliability of the AWT charger's impedance measurements that are in some hitherto unknown units depicted as mR. IMO you need a 4 wire setup to measure internal resistance of batteries but the numbers given by the charger are better than nothing. Lab grade they are not. |
