I was preparing to get my Twinkle back in the air and thought I’d charge up a pack or two for it.. Well.. I broke all the cardinal rules of lipo charging, especially when concerning the Astro 109.To make a long story short…
Tuesday. I threw a 2S pack onto the charger with a voltage of around 8.0v.. Almost charged.. Well, the 109 said. “Ok. 2S.” and started charging. Well, I didn’t wait to confirm “2C2”. So the 109 went to work, and went from 2C1 to 3C2. Rut-roah… POOF goes the lipo. I have several LipoSacks, but had not been using them, so anyway, the Twinkle, my workshop and my pride went into a flaming molten lipo goodness. I grab the flaming lipo, throw in a 5 gallon bucket and run outside. OK, lesson learned… use the LipoSack.
Wednesday, I decide to again, charge some packs… Throw a 2S INTO THE LIPOSACK and THEN on to the charger. Voltage around 8.0v… and well.. the 109 said. “Ok. 2S.” and started charging. Well, I didn’t wait to confirm “2C2”, so the 109 went to work, again it went from 2C1 to 3C2. Well… I noticed the sickening smell of impending lipo excitement and look over, sure enough, I’m catching the “vent”, grab the LipoSack, go charging for the nearest door, only to have the deadbolt and the door locked. Poof goes this lipo. This time, in my hand all in the living room. I was “lucky” in that my body and clothes absorbed most of what shot out of the sides of the bag, the rest was all captured by the bag.
