Don't spread misinformation and scare people just for the hell of it.

Even the epipemods USBaux uses a HTC EVO phone battery!!!

That doesn't necessarily mean it's a good idea. Is the battery designed for rapid discharge? I would think that cell phone batteries are designed for a long, slow, gradual discharge. Does it have any kind of protection circuit?

Just because you CAN do something, or just because others HAVE done something, doesn't mean it's safe or a good idea.

All battery mods are deemed "unsafe" via ECF, unless a certain criteria are met (i.e. venting, protection circuit, etc.) Regardless of whether this battery is safe to use, I think the OP is questioning the battery's function. I'd have to say I doubt it. Depending on the actual cell, it's my understanding that most cellphone batteries are rated for .5amp discharge. A typical 3.7v e-cig circuit draws somewhere around 2amps (alot of variables). You would need 4 of these batteries in parallel to come up with 2amps of discharge current, but of course this would give you 6000mAh of capacity, too. There are more cost-effective, high_drain batteries in the form-factor of a cellphone battery on the market.

If you're intent on trying to use your li-ion cellphone battery, do youreself a favor and construct a dummy circuit with it to test function. If you're satified with the cells ability, build away. Be sure to keep in mind that the battery's stored energy can become volatile and explosive if misused.

most cell phone batteries won't stand up to the draw current....

The battery for my android tablet max output current is only 2.3 amps... which is somewhat on the weaksauce side of things... and leaves some danger for ruining such a battery... and yourself. You want to have at least 3-4 amp max output current, which most phone batteries just don't have... especially if it is not a smartphone battery.... Some 4G type batteries MAY be able to handle 3-4 amps, but they are designed for quick charge, and long life, unlike an RC type battery which is designed for high discharge rates... which is why you end up with different energy densities given the same material construction between the two types. it is all about what is on the inside.... not quite as simple as voltage and capacity. Over discharging can result in catastrophic failure at worse... very shortened battery life at best.

Just want to ask if this is ok? i like to make my 1st box mod with this battery... TIA
