Not what you think;^)
Someone once described to me how quickly a 2-33 burned as he pulled it out of a grass fire. This 'crash' was in the online media, but one significant item was left out of the article. Read on. http://www.ntsb.gov/ntsb/brief.asp?e...01X51612&key=1 |

The other article is no longer available on the web. |

Those batteries are capable of heating a wire quite impressively. The problem must have laid in the fact that there was not a proper inline fuse. I have a couple of these batteries, and on the hot terminal, about 2 inches of wire, then a 15 amp fuse. You have to protect against shorts, or sooner or later, one will happen. -- Jim in NC |

Seen it happen... Careful out there, this electricity is dangerous stuff. See ya, Dave |

See ya, Dave Yep, I built a small wooden box with a handle and cigarette lighter outlet on it for use with odd things. About impossible for anything to get to the terminals. Plus I use the cigarette lighter outlet for charging. -- Jim in NC |

Being aware of this potential risk may save someones life. Every pilot should make sure their glider battery is well insulated and has an inline fuse. A fuse box on the panel is not sufficient! A similar incident consumed a whole glider and trailer some 10 years ago due to a short while trailering the glider. It is amazing how many things can go wrong which can kill the pilot or destroy the glider. In 13 years of soaring I think I heard about every possible way to kill yourself or destroy the glider, from improper setup, obstructed controls to oxygen fire and many more. Just about anything that can go wrong, did go wrong and killed or almost killed someone. The more you know the more you can protect yourself. Thanks to RAS I know more than I could ever learn otherwise. Ramy |

would the RAS brain trust recommend hot glue over each terminal to
prevent shorting out as well as being a bit of strain relief for the wire coming off the connection? I also need to build a box for the battery in the Cherokee...Thanks for this post Frank I hadn't ever given this subject much thought. I'm afraid of fire. |

The description to me was from the time the fire started at the tail of the plane he had enough time to open the canopy remove a seat cushion and get away from the airplane. It burned very fast. I lost a good winter vario in the glider. Brian |

There is something out there better than hot glue. Go to a big box home supply house, and look in the area where professional electrical tools are displayed, and near them and other things like electrical tape, wire nuts and the like, you will find what you need. You want liquid electrical tape, as I believe the stuff is named. You dip what you want to insulate in the stuff, and it insulates the connection as it sets up. It is good stuff, and similar to what you use to dip tool handles into for rubber insulating grips. Don't make that your only protection, though. An inline fuse, even one with a pretty high rating, close as possible to the battery is your best friend. So is mechanical protection of the battery and wires, all of the way to what is consuming the electricity. -- Jim in NC |
