Sorry to hear that Punishment,
I am not sure the only reason they explode is being tampered with, there are many levels of failures. And sometime you just get a bad cell or charger, that is why I want to start adding the safety chips to them for one more level of protection.
Here is what I had:
The charger was a lith smart charger for 7.2 volts
Standard 25 watt pencil iron
Method of assemby:
Did not heat the cell up, the wire went through the tab hole and heat applied to the wire not the tab to keep heat to a minium.
Now what could have happened,maybe hard to tell,
I had a long run with that pack and may have overdischarged them ****aging the cell but, I did not check to see if they dropped below 3 volts, hind sight is 20/20.
I am sure it will not be the last to explode on me, lol
