	'''Conclusion:''' Although there are benefits to using the A123 LiFePO4 cells, it is the opinion of the tutorial creator that the Li-ion pack has a more favorable nominal pack voltage window (slightly better performance in most situations) and is ultimately similar in safety. The availability of Li-ion cells is also an advantage.
