Battery and charger combo

[v8der]

Hey guys, noob vaper here. I recently purchased an ipv4s, and haven't been able to try it out yet due to lack batteries. So in my downtime Ive been trying to do some research on vaping, as many aspects as I can. The only thing that I cannot seem to get a straight consistent answer on is what is the best, safest combo of batteries and charger to use. I ordered ultrafires but have been warned against them, even though they are protected batteries. Will my mod prevent over discharging, and also the batteries melting in my hand? And is there a charger that'll automatically shut off so the batteries don't overcharge? Sorry for all the questions, as I'm this as been answered before, i just haven't been able to find it. Thanks guys!

In general, protected batteries aren't much use for other than very low power vaping as they tend to have very low amp limits.

For vaping you need cells rated for high current. The best of these are made by Sony, Samsung and LG. Thee may be equivalent Panasonic cells but I'm not aware of them.

Anything that claims a discharge of more than 30A is not telling the truth. Anything claiming a capacity of over 3000mAh is probably not suitable for vaping.

There are fakes of all the good cells out there, especially Sony and Samsung cells.

LG cells are less likely to be faked - but this could change.

Chargers - buy one of the ones that Henrik recommends at www.lygte-info.dk. His tests are very thorough.

Yeah, ipv4 will discharge suitable batteries safely and will only drain them to around 3.6v 3.7v as to not damage their capacity. Lghg2 batteries are truly very good in the ipv4, from experience. 
I use a couple of these chargers, had them for a while with no problems at all.

So I currently have efest batteries, they came with the mod. Will these be okay with a uwell crown with .25 ohm dual coils, at around 60-100 watts?

They'll most likely be fine. One of the purple ones is labelled with a dangerously over specified amp rating. The 20A ones are actually 4A cells. The other purple ones are OK albeit with higher amp ratings than I'd be happy using them at. At 100W I'd want to use two 30A rated cells. The 30A purple Efests are 30A cells. The 35A cells, are actually 22A cells - they are LG HE2 cells under the wrappers. The 30A cells are Sony VTC4 cells which are genuinely 30A cells.
