why do you have to be so stupid and insulting? you could just be quiet and you would not be so offensive. seems like you always gotta make some insulting statement or prove how truly ignorant you are.

You all need remember we are not perfection human being so Greg made his mistake gotten
him trouble. No one is invincible! Just like what happened to my Headway battery pack got fire caused
by shorted. Lets move on please!
the rules of physics apply to everyone. i'm not sure what's confusing here. the lipo rules have always been: never below 2.7V, never above 4.3V, and never puncture. those are the rules. i apparently broke the rules. let's take a poll of lipo users and see who've had cells above 4.3V and below 3V. the rest, like in that article, is a lot of good advice. you may even consider them rules too. maybe i will stop charging unattended. i think a smoke detector may be more reliable than me and an eaiser solution. either way, i wouldn't consider that a rule. that dude is no scientist. he even says:etriker said:Lipo rules are for newbees only ?
i'm no expert either. i learn everyday. i make tons of mistakes. i document them too for your benefit. in lots of ways i'm still a noob. but there is no us and them. we're all individuals with different levels of experience. don't trust anyone cause he was a member since 2008... read and read and read. and be freaked out.John Salt on his About Me page said:So why do I claim to be an RC helicopter expert? Hey, I never claimed that. There are radio controlled helicopter pilots who could fly circles around me. There are aeronautical helicopter engineers who can teach you way more theory than I ever could.
I am simply an ordinary person and average flier who loves the RC helicopter hobby and wants to help others experience that same passion while avoiding many of the common mistakes and pitfalls.

you can do a new layout space in the garage and leave a space for a charging closet or box that would be lined with fire resistant sheet rock.
maybe have a wheel rack to hold the bike upright and then lower a sheet rock cabinet down over the bike while charging.
use some foam strips on the bottom edges of the box so when it sits on the floor the box is air tight except for the charging leads going into the box which could be sealed with fire stop where they go through the side or top of the box. this is a high temperature caulk used for sealing holes between floors to prevent spread of fire.
maybe have an access panel of sheet metal which would open and close on one side where you had to reach inside the box to make the charging connections. then close it when charging to keep the box sealed.
i already recommended people consider using the GFCI breakers for these alloy shell chargers because of the risk of a shock hazard. your charger became a shock hazard when the ground wire burned open. i have since opened a brand new kingpan charger and found that the ground was never even attached to the case during assembly of the charger. just loose inside the charger where it coulda shorted to the high voltage even. the switching mosfets can and do short to the case when they fail and if someone is grounded and picks up one of the chargers which is still active but has the high voltage shorted to the case and the ground is burned off then they could receive a serious shock.
smoke alarm. code now requires that all new smoke alarms be tied together so that if any one is set off then all of them in the house will alarm. this would require running another small wire from the garage back into the house to tie into the other smoke alarms. easy enuff to do. this may get you over the hump with the fire insurance if they get on your case about the source of the fire. maybe keep your rates from being jacked up too.
fire suppression. water sprayed on the heat source will reduce the temperature a lot and may prevent secondary ignition. in conjunction with a charging closet, using a spray nozzle and stored volume of water to be sprayed on the fire as soon as the thermal relay closes may be easy enuff, but you wanna have the water pump on a separate circuit from the charger because you can expect the charger to blow the circuit breaker.
you can rewire that service box with 240V from the service panel in the house using the current 12AWG romex running out there now. you could do it yourself or hire the guy who worked for you before. he will know how to wire the third wires for the smoke alarms too. he could install the GFCI breakers in that service panel in the garage and bring out several circuits from the panel there.

open your eyes, and read what i frocking wrote, you assholeetriker said:That is why I said crazy.
How does he know his insurance man won't read this ?
He is already planning a new workshop and still might charge unattended ?
thanks for getting me thoroughly pissed off, on top of all the other shit i have to deal with.GCinDC said:maybe i will stop charging unattended.
that is an amazing idea! i love it!hydro-one said:i like the idea of a |fume hood" for charging.

IMHO something pretty tramatic happened to GCinDC and he is processing it. He was a good enough chap to share it, pretty much unedited, realtime, and raw with all of us so we could learn something. I am absolutely sure he has pondered it, processed it, and will make some future changes.
The man could have lost everything, and I for one, think as an other poster said, "someone upstairs was keeping an eye on things for him!" I couldn't agree more.
That said, I have done some things that seemed right at the time, and considering the outcome, were pretty foolish in hindsight. People mess up, organizations mess up... just ask NASA about launching Challenger!
I for one appreciate GCinDC's posts and the chatter and analysis that has ensued.
In my opinion you have moved into making ad hominum attacks on his character, and I believe they are out of bounds and not in the spirit of the board. I am asking you, respectfully and kindly to simply shut it down on this thread and move on.
All the best,
bigMoose
