Besides,
There's like multiple cell types that you can order with "Zippy" batteries (Korean, Chinese-1, Chinese-2) many different sizes, different discharge rates, etc.etc.etc.... So it would be impossible for me to make any kind of blanket statements.
I guess I'm not sure why people always try to save money in batteries -- they are the most important part of the system. Poor batteries mean poor performance, and good batteries mean good performance. So buy the best batteries you can afford, and skimp on the "bling" parts.
