Hi Clare, Jim, everyone.
These are DeWalt powertool batteries - 18V (20V?).
This characteristic you identify "1C" etc. becomes knowable?

  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.
