United Hobby Send them back to us... NO WAY
I have been sending e-mail messages back and forth about some 3 cell 1700 packs I have. One has been charged 1 time and the othesr don't have connectors on them (new and unused ). These have puffed up and I have been instructed to send them back. Well I was in the garage this morning and smelled smoke. One of the new packs that was on top of the work bench started burning up. This pack has been untouched for over a week.
There is no way I am going to mail these anywhere and I am amazed that they can be sent through the mail. I am glad for the slate countertops on my workbench.....HOUSE BURNED DOWN AGAIN>>>>> Keep your packs in a fire safe or other unburnable location...they can self destruct at any time without warning....!!!!! THIS COULD HAVE BEEN UGLY|!!!!!!!!!!!!! I am ordering some more of the Rhino Packs though. Be Safe Rick |

Airliner brought down by Lithium Battery...
I am not going to put these on a plane unless they are in a fireproof container. That would cost more than the batteries are worth...
Yes, as received, unused, no connectors, not charged. They are puffed a little more than my other United Hobbies Batteries. I see they have a 90 day return policy now. These packs are the ones that they replaced from the previous return. ( I am past the 90 days) I had 5 of the 3 cell 1700's and 5 of the 3 cell 1000's. The 1000's seem fine and of the 5, 3 are still unused. Of the 5 1700's, 3 are bad of those I have charged 1 of them 1 time, and been using 2 of them without any problems so far. The other two as stated, unused in factory new condition. One of these is the one that started burning. I took a photo but my camera is not that good. Some smoke and black stuff. Looks like all the other photos of burned up batteries. All 3 cells burned up. I am not complaining, I have some of the packs that I have been using without fault...My concern is putting these in the mail and the spontaneous combustion thing happening and me being at fault.

What packs are those? Brand _____?
It is no secret that when a pack puffs it is full of flamable gas. If enough pressure is there it will vent. When venting it is possible (very likely) for the outgoing gasses to generate a static spark and ignite. Imagine these on a plane over the Pacific ocean when this happened? Whoa!!! If sellers are not careful they will put an end to the mfg/selling of lipo's worldwide. Oh, send a link to this page to HC. They need to know of this. Rick |

If they were really untouched, I am curious whether they still respond to emails..
It could be crazy to have hundreds or thousands of such packs in stock, one by one, stacked up in boxes.. close to other packs and balsa planes.. Do You think that they should sale them fast? |

Simply hook up your LiPo to an automotive light bulb (a 7443 tail lamp for example) and allow it to fully discharge. Snip the leads and dispose of in a landfill... Jack |
