All Li-Ion packs are not created equal. Charging rates depend upon 
capacity, and proper Li-Ion packs have built-in protection modules. 
Study batteryspace.com to get a handle how these things are built.  This 
company is "the American partner" of a small battery mfr in China. The 
Chinese company manufactures the cells, the American company puts them 
in packs with protection circuitry and suitable connectors, and does the 
marketing.

My neighbor, W6GJB, bought one of their bigger LiFe 12V packs. Looks 
quite solid.
