iPV4 Exploded

[Kevin O'Brien]

Hey All-

Long time reader, first time poster. FYI, two days ago when taking my battery out of my ipv4 with a brand new battery in it mind you, my connection sparked and the battery vented. Then the battery lit on fire as well as the entire battery casing on the mod. The batter then "poofed" and burnt a hole through my bed comforter where it was laying. It looks like an IED exploded in my bedroom. WTF?!

Sounds like you put one battery in correct and the other incorrect, shorting them to each other. I don't know it the IPV4 has protection for this, but I doubt it. It probably only has reverse battery protection in the event you put both batteries in wrong. Most dual battery devices have this flaw.

 

[suprtrkr]

+1 to @RandyF that's my best guess too. Don't *do* that! I hope you are safe.

It does. It won't turn on if even one battery is in backwards. I accidentally did it the other day. No problems, so I assume the battery posts are isolated from one another. More likely the charging board problem.

Not sure about this one. I had one battery in correct and one incorrect one late night. Ipv4 just would not power on. Took of the cover looked at it, slapped myself in the forehead "DOH" moment... took it out flipped around put it in, powered up like normal.

We need to see pictures...

 

[Ou2mame]

Yeah post some pics of the mod and batteries

Does this type of PV have to be turned Off when handling the batteries?

 

[Hans Wermhat]

If the bat vented in the mod, there's prolly not much left to take a pic of. It's all plastic.

I have yanked the batteries with the mod on.

Sounds kinda fishy to me. Batteries don't just "spark" and catch on fire. Did you have batteries compatible with the IPV? Did the batteries have a proper charge? Are both of the batteries the same brand? Was the mod on when you were putting the batteries in? What do you mean by the battery just "poofed"?

Sounds too weird to be true IMO.

Be very careful with these type of batteries as there is lot of energy stored in a 18650.

Take your time as these devices are powerful and expensive to replace.

As long as you were not hurt that is the main thing.

Lesson learned.... we have all flubbed up in one way or another in this great hobby...

 

[roxynoodle]

It is very likely due to the charging board shorting on the 510. Honestly, that mod should be recalled over that charging board.

I've accidentally put a battery in backwards on my old Sig 100W, which uses a long ago variation of that chip and it does indeed have reverse battery protection.

 

[HighPlainsPuffer]

Just curious, what kind of batteries were you using? Sounds like a pants wetting episode to me! Very scary, glad you are fine!

 

[Kevin O'Brien]

Why would I make this up? My iPV is currently en route to California for a warranty replacement. As for batteries, I was using MXJO 18650 3.7V 2500 MAH.

Precisely what "connection" sparked? The battery to the battery terminal, or something else.

Then the battery lit on fire as well as the entire battery casing on the MOD.

This should never happen with an IMR battery. They vent when overloaded or overheated, but they should never catch on fire. Catching on fire suggests that the battery was really a Li-ion rather than an IMR.

MXJO are re-wrapped batteries. I think they are actually Panasonic or something like that. I hear they are decent, but at higher watts, I am always more comfortable with a higher CDR rating. I use Sony VTC4s in everything. You really need at minimum a true 20A CDR battery for the iPV4. 30A for anything over 75W is always a good idea if you are going to run anything under 0.5ohms.

Pictures would be most interesting

i was running a build at .12 ohms, 110 watts. the battery lit when i pulled the lanyard and popped the batteries out of the mod. the + side sparked, then started smoking like crazy and hissing while it vented. I tried to roll my comforter over it in case of fire, as I could not touch the mod out of fear of getting shocked ( i have a pacemaker ). There was then a pop from under the comforter. When i removed it, the mod was melted in the battery casing and a huge burn hole through the comforter. Im sure I could have handled it better, but see how well you react when you have half a second to make a decision!

do you have a link to where I can purchase some? Thank you in advance.
