Was it possible that you had a radio turned on in close proximaty to the charger. I found that if I was charging a pack, then turned on my M8 (within a foot or two) the voltage as displayed on the charger would jump up to 10-11 volts, then if I turned my radio off or walked away, down the voltage came and off with the charge (false peak). If you had your radio on next to the charger, the voltage could have been unstable and the charger wouldn't have been able to pick up the peak, therefore overcharging your pack.

Check it out sometime. Start charging a pack, then turn on your transmitter and move it close and away from the charger while charging and watch the voltage reading on the charger freak out. It does this with M8 and I think futaba.

I adore the work you made with your charger? did you do it yourself? Was it hard? Care to share it?

The quasar pro is the best charger for me! Maybe the settings were wrong, or maybe he was charging TX packs then charged the packs without changing the settings.

Quasar Pro still get my vote!

Adrian - haha, alright! For some reason, I had a pretty violent image in my head. Thats not so bad. When you listed all those chargers, I could only think..... "Hmmm.."

It sounds to me that when the shrink wrap exposed the outer part of the battery which is negative that it could have shorted out against a battery bar and BOOM with an overcharged battery.

That or each cell casing shorting out on the other but this only goes to show you double check your chargers settings.

My friend had one of their charger but they wanted $90 to fix it. The problem is there are many people blowing up GP3300 with Qusar Pro charger. AE is now considering a recall on all the units still on the shelve.

I had a pack vent IN MY BATTERY CASE! Like a dumbass, I pulled the pack out of the car and tossed it in the case (the Trinity 8 pack case) hot with all my other packs. I was in a hury to leave after the race so I was paying no attention. Got home later that night and pulled my box out and noticed a really bad smell. Went to open the case and noticed the black vinyl was melted. Opened it and six of my packs were fried! All of them were new 3300's. This was a couple weeks after the Reedy race and I had bought some brand new GP3300's for that race. I was so pissed at myself. The only thing I could think that caused it was the hot pack with no ventalation kept getting hotter until the shrink wrap split and boom.

I've got two of these chargers, the newer one I use for 4 cell 1/12 scale and the older one for 6 cell TC stock. When I try to use the older one for 4 cell packs, it overheats and shuts down, plus the fan does not run as much as the newer one. Anyone else experiencing this? I don't want to spend $90 to fix this!

Im not sure why it would get hot and shut down on you. With mine the fans always run more when I charge 4 cells compared to charging a 6cell pack. With the 4 cell it runs constantly with the 6 it goes on and off.

The fans are not temperature controlled. They are on timers.

I have put two side by side, and pressed the start buttons at the same time. The fans cycled on and off at precisely the same time.

Actually one fan is constant on and the other one is thermal controlled based on the heat sink temp.
