Are you saying that the batteries that caught fire, was not supposed to be charged at 5C? In all the years that I've been using LiPos in this hobby, I've never charged at more than 1C, no matter how much of a hurry I was in. I even get the eeby jeebies charging a 5000mah, 6s battery at 5A (1C). I find myself going up to them periodically and feeling them for heat.
One of the guys at one of my flying clubs burned his garage down and almost took the whole house with it (charging LiPos unattended - don't know at what C he charged at).

LiPo Safety
I love flying my RC planes and Jets as much as the next guy. However, we often forget that these aircraft run on LiPo batteries that have the potential to cause serious damage if not properly charged and / or stored. I learned the hard way and wanted to share my experience with others, in order to avoid such things from happening to others. I bought a multiple battery charger was excited about using it. The idea of charging 6 batteries at one time seemed very appealing. What I failed to do was follow instructions and charged the batteries at 5C ratings. I had a combination of Hobby King Turnigy batteries and ChinaHobbyline batteries. All 6S batteries, with some at 30C from HK and others 40 C from China Hobby Line. I left the charger unattended and within a few minutes the Hobby King Batteries started to smoke and the heat spread to the adjacent batteries. Luckily I was able to get the situation under control. I sent an email to Both Hobby King and China Hobby Line to just inform them of what happened. I was not trying to pass blame or make them feel bad about what happened. Hobby King could care less. Surprisingly China Hobby Line offered to replace all the damaged batteries for free, including ones from Hobby King. I didn't expect such support from ChinaHobby Line since it was totally my fault. I asked if they could just replace just the ChinaHobbyLine batteries and I would be happy. Aside from Motion RC, I have never seen such customer support, but I'm not complaining.
I'm sure everyone knows the importance of charging batteries properly but just as reminder, look at my photo and make sure this does not happen to you.
