its funny how you say you wouldnt use a cheap charger, kinda suggesting that normal people need to plunk down $100 for a charger, with some cute brand name, and complex capacity to do things.
yet when they blow up the cells in TESTING, what do you think they use ? A High amperage hobby charger.
because these overpriced chargers need a expert practicaly to operate them Correctally, and CAN exceed the specs for a cell, mabey a expert would want to use them, but there is no need for the consumer to try and charge FASTER to be safer.
lots of these cells are tested to 5V <--- yup WAY over, to see if they will start a fire, and they do not, untill you increase the AMPerage too.
while telling people to avoid cheap chargers, that go OVER spec when charging, is a good idea. The TOO high ones need to be identified, but the current on a cheap charger is so low, that catastrofic failure is LESS likly than a improperly used FAST charger.
if people aint gonna plunk down the cash , and time , and read manuels, they are better off with a LOW amp rate, then a High amp rate charger.
look at the specs for the Caused Fires, they are always pumping in some major juice.
ID the junk, and stop the sale of it alltoghether, its not good enough to say "pull it when its green" , it should be the thing sucks send it back, dont use it.
there are a lot of good SLOW chargers, and the day you see people setting them up out back to blow up batteries, you can convince others that they will.
Wheras the high end hobby chargers Misused are what you CAN/DO start a fire with.
we need good chargers, consumers dont need FAST chargers, nothing good will come of that, and proof of that is What exactally were each Fire causing event using? High end RC fast chargers, and fast high amp laptop chargers.
if i was staging a fire event, the last thing i would use is a nano.
ID the junk , but dont increase the rate.
