<div>Ho Hum. Where is the video? Only a crummy picture of ashes. Flames would have been more interesting. :-)</div> <div> </div> <div>Seriously, good thing you did hear it.</div> <div> </div> <div>Bob R.<BR><BR>>http://www.rcuniverse.com/forum/m_4056141/anchors_4064428/mpage_1/key_/anchor/tm.htm#4064428See <BR>> picture on RCU.I had a bit of a set back today with my winter fun 40 sized <BR>> glow to electricconversion. I had wanted to try the Thunderpower 4200 <BR>> instead of the Tanic3600. I set off to the field with a borrowed <BR>> Thunderpower 4200 mAh pack. Iset the Astroflight 109 to 2 Amps. It ent to <BR>> stage 1 and was calibrating toa 3 cell pack and was well on its way to <BR>> charging the pack, or at least so Ithought . I have done this <BR>> topping-it-up many times before. I set it on a 2Amp charge rate.I never <BR>> made it to the field. I heard a light "Phuttt!" about ten minutesinto the <BR>> journey. I stopped
the van and ran back to the back doors. Thebattery was <BR>> bloated and looking bad. I grabbed the Deans connectors andunplugged it. <BR>> Dangling it by the lead and as far away from my face aspossible I lowered <BR>> it to the curbside.I then personally backed up and was about to move my <BR>> van forward a bit . (Ihad just put 3!<BR>> 5 gallons in it!). Seemed like a good idea to get clear. Neverhad the <BR>> chance. The pack blew up in a ball of flame about a cubic yard insize and <BR>> proceeded to burn fiercely. I had grabbed the fire extinguisher butdecided <BR>> not to use it.The local police joined me for a while and seemed more <BR>> interested in theplanes in the back of the van than the charred remains. I <BR>> scraped all of thebits up to keep the country side pretty. Estimated that <BR>> the grass would growback soon, and went home.Fortunately I was able to get <BR>> it out of the van before it blew up intoflames etc.Long and the
short of <BR>> it is. "Do not charge a fully charged battery with anautomatic <BR>> charger"Dodged a BIG bullet today.....Regards,Eric.P.S. If 3 fully charged <BR>> cells = 12 V plus, and 4 discharged cells = 12 Vplus, then how does the <BR>> charger know which is which?<BR></div>
