     If it is a MAX it is a 5S x 2P pack running LG HB4 1865 LiNiMnCoO2   
   cells rated at 1500Mah with a max current of 30 amps which is a 20C   
   rating!!!.   
      
   I strongly suspect the 5Ah pack uses higher capacity cells - which   
   ALMOST ALWAYS means lower max current rating - so you likely made the   
   right move.   
      
   -------------------------------   
   5S x 2P means two columns (Parallel) each stacked 5 cells high (Series),   
   thus the output is 5 times the individual cell voltage and the current is   
   twice it.   
      
   The SKU (Stock Keeping Unit) number matters.
