There could be many causes of electronics failures, but for a short circuit in a battery the following are some possible causes to consider and test:
Please reference to this FAQ for SCD debugging. How to debug FET failure resulting from short-circuit testing
I am inclined to say this behavior is due to bullet point number 4 above. The gate of each FET requires a small gate resistance to avoid oscillations. Please also reference to this app note - Tips for Successfully Paralleling Power MOSFETs
