Finally convinced to get rid of puffed lipos.

Realized it wasn't worth the risk in charging or flying with them, so hooked them up to a 50 ohm 10 watt resistor and let each one discharge overnight till the resistor was cold again. At least I was sure they weren't discharging at too high a rate.

Warning, the resistor gets hot during discharge, I used an infrared thermometer to check the temp.

While these batteries were not that overly used, they were a couple years old. I think my main problem was charging them too fast. When I first got my charger, what I read had said to charge at 2C, but everything I see now says 1C. So, I'll be changing my charging procedure.

My charger has a temp probe I can use, so I will be using that from now on, and I do use a metal can to contain the batteries during charging. I always charge them attended with a fire extinguisher close by.

Just went and ordered new batteries. Should be worth a little peace of mind.

2C vs. 1C charge rate will have zero difference on usable life. Storing in fully charged state, storing in a warm environment, and overdischarging by relying on low voltage cutoff are far more damaging to lipolys.

Store in a cool area in a discharged or partially charged state and only charge prior to use and your lipolys will reward you with a long life.

Glad to see you got rid of all of your damaged LiPo batteries. While I understand it's a free country, I don't understand why people insist on using damaged LiPos when batteries are so cheap. The risk just isn't worth it. I may be a bit overcautious but any LiPo that's damaged even the slightest gets discharged and disposed.
