Never heard of them. are they a bit tougher? i just made an order at TCS and figured id throw them in so i had some options/spares.

The charger may be defective as well then, because the first time i let it go to 4.26 before shutting it down. i dont know if if would keep going or not. the charger is kinda a cheapy entry one ill just have to watch it closely as it charges that one pack to make sure i shut it down before 4.22

thanks for the welcome btw, this forum is indeed a gold mine. i was recommended to come here since there was so much knowledge on BL, and lipos.
