uhhh, the "ehits" battery is 3.7, fires from 3.3-3.7.

...atleast the ehit im looking at on the net right now.

That is all fine and good for nominal rating. However 3.7v batteries charge to a Maximum safe 4.2v.

However a lower amp charger will simply slow charge a battery an may not reach full charge. This is not the danger as it is input current to the battery. Over current is an issue.

Remember, a 12v car battery charger can charge to 14.8v. The amp push dictates the speed at which the battery is charged. 2amp, 10 amp,etc.
If you attempt Cranking the Car you create a surge and the charger(good one) shuts down.
Boost start is timed to protect from overload.

but wouldnt the warning on the charger to not use a 4.2 battery be towards its nominal value rather than its rated value, being that the battery is advertised by its nominal rating? rated value can vary every battery due to conditions so how can it indefinitely be rated at 4.2?
i have a pretty basic understand of such things so my perception may be off.

I don't think it's the same thing. The E-hit is/was a rebranded Ego style battery with a soft silicone fire button. They are/were also sold as Elite (650mAh) and Elite XL (900mAh). I have one of each of the latter and they've been good batteries. Very well behaved, and very reliable. But I treat them with respect and don't plug them into a laptop or PC USB port. I've always used either the wall wart that came with the kit (my first), or my Duracell two-port wart that has additional safety circuitry.

That little "dongle" charger would have come with a 510 (cigalike) type battery (most likely a kit). normally 80 to maybe 250 mah.

She buys a 650 mah batt. She doesn't know a mah from toenail. She see's it fits her little charger so all is good with the world. I think the dealer should have at least asked her if she had an EGO (or equivalent) charger. It demonstrates why some of the US manufactures are banking on proprietary Cig-a-like products. The American BT companies don't trust us vapors enough with a common charging type standard because .001 percent of the population are bound to generate multi million dollar lawsuits.

i cant find a single ehit on the internet being sold that says it has overcharge protection. all im saying is that im assuming the "dont use 4.2v batterys" symbol would mean 4.2v nominally, and the ehit is nominally 3.7 aka under that. i think the pop was due to overcharge, its easy to do, happens all the time in many different devices with batteries in them. if you just keep putting more and more energy in something itll eventually reach its limit, without overcharge protection it continues to fill the battery like a water balloon, untill it pops.

iv seen dongles being sold with 4.2 volt egos, as well as cigalikes, just doesnt have a cord attacted. i have no clue what the specs are for that specific charger she was using therefore i cant blame the charger.

Ive repaired a few of my own ego chargers. there is definitely a voltage regulation circuit on the pcb (printed circuit board) mounted in the connection end. I'm sure some companys make a dongle that can handle 4 volts, it just looks like the one in the article isn't one of them.

yep, im just going by the battery then because you can look up the batteries specs.

Shenanigans indeed .
Unspecified charger is plugged into an unspecified PSU , and an unspecified battery plugged into that lot .
The woman "It was a kaboom" , well it didn't blow the half inch of dust off the front of her filthy computer [EDITED] .

Add to the above the very dodgy news report . (Strickland should have to stuck to selling Propane) .

It is as many of you have said , she has bought the cheapest of the cheapest in such a critical place .
Then when the cheapness turns to bite her in the ... , she cries wolf ... well she actually cried "12 foot tall werewolf kaboom" .

We will get these kinds of stories with sensationalist news as long as the government are deliberating .
