Default Can i bring this lipo back to life

hi all, i just bought a thunderpower 1320 today and when i put it on my accucycle elite i got a message stated, cannot charge voltage too low!!! the reading was at 3.7 volts for the pack. is this thing far beyond gone? i can;t believe the voltage was that low. i put my other pack on there i bought, exact same pack, and it charged just fine. did i get a defective pack?
if i contact thunderpower, would they send me a new one.

A friend ran his Lipo pack down too low last weekend. The Astro109 wouldn't touch it because of low voltage. We hit the pack with 250 mA with a Astro 110D until the voltage came back up. After that, the Astro 109 would accept it. We did loss a little capacity but the pack is fine, so far.. The simple thing to do is contact TP. Most likely they'll replace it.

Contact Thunder Power before you try anything. If this is a 2 cell pack, it should have read around 7.6 - 7.8 volts when you got it. Sounds like a defective pack.

Sounds like a dead cell to me, fully charged lipo cells are 3.7 volts each. I would definately contact Thunder Power.

You know I was wrong earlier a fully charged cell is 4.2 volts, 3.7 volts is what each cell is rated for, and 3.0 volts is a discharged cell. I would still contact Thunder Power though.

Yes, if a new pack isn't behaving as expected, ALWAYS call the manufacturer for advice.
