Iknow this is a little of topic but i had two lipos in my hpi savage last weekend ones a 11.1 2200 15c, and the others a 11.1 4000 15c. Both batteries wont charge the 2200 when charging says cell volume to low and the other one says its a 2s but then when charging the middle cell goes from 0 to 2.1 in about 5 secs none of them got hot or went under the voltage minimum while running only after i unplugged them to let them cool to charge again did they say 2s and low cell volume. I have battery voltage monitors on both battery so i wouldnt go under the voltage min. is it just a feak occurance or was it because they arent the same batts. Is there a way to bring the cell back to life or is it toast.
