Melting heat shrink and soften solder on A123 pack

[snellemin]

Hey guys,

The heat shrink is shrinking even more and the cells are showing. The solder on the balancing cables are softening. This is a 3s1p pack that goes in my FLM rustler. It has enough punch to pop wheelies all the way till the pack dumps. I started noticing this last sunday at the dragrace. I'm thinking I'm pulling more that the rated amp discharge rate of the batteries with the Mamba Max setup with the heavy rustler. The 3s2p setup should reduce my heating problems, correct? Or should go for a different motor?
