Lipo is acting strange, you ever experience this?
So I have a SPC Lipo, 2S2P 8000mAh 12C about 3 years old. This battery has been rock solid. My last run it ran fine, and I went to charge it it to about 50% because it will sit until the weekend (about a week). I put it on the charger and it hit 8.4v at around 3300mah. The battery was totally dead, I ran my rustler for about an hour with the battery and the LVC kicked in. Now i will put it back on the charger probally Friday night for the weekend but I a little worried that the battery is shot. Each cell coming off the charger was with in 0.1v of each other.

What are the volts at?

When it first came off the charger they were at 4.2 each, but after like 10 minutes they dropped to 3.7 each

That's still 7.4 volts, so it's not bad!!

yes I understand that , but when it hit around 3000mAh it started to reduce the charge current already like it was getting close to peak, remember this is an 8000mAh battery that was totally dead, it will never hit 8000mAh when the charge is starting to reduce at 3000mAh. Typically this battery would start to reduce the charge current around 6500mAh.

Yeah, that's the just of it, I have an old reedy that I use for bashing in my drifter, it's like 2 and a half years old, and it's sposed to be a 5000 and it will only take 3000 or sometimes 3200 so it just happens when they bet old!!
