I just got a new 4000 3s 11.1 traxxas lipo. I have a bad cell and the battery is starting to swell. I only used it 3 to 4 times so far. I understand there are problems with new products but I'm concerned they will not warranty the battery. I charged it correctly each time and even used a balancer. I also ran the battery in the correct mode each time. I was extra careful to do so since you hear bad things when you miss manage a lipo. Does anyone know from past experience about traxxas sending you out a new lipo in this case? I hope so since I don't have the money to get a new one. I took me a while to get the cash just to buy this one. Mortgage and bills came first !
