My son and I received our new 2S LiPo's yesterday (Tuesday). Charged both and went out with our Stampede's. I lost a pin in my MIP axle after 10-15 minutes. My son played with his for about an hour before having to go in. Neither battery was discharged to the point that the ESC cut them off.

My question is, do I just throw them back on the charger and bring them back up to 100% to use tomorrow (Thursday)? Or just leave them as is and use them until the cut off point and then recharge them afterward?
