I am interested in Lithium Iron Phosphate battery technology for the big weight savings compared to other batteries, but I have heard that they do not do well in warm environments such as in the engine compartment. I am also concerned about the battery overheating from improper charging. Is the warm environment concern justified? What special design considerations are there for a charging system with these batteries.

BTW, rumor is that a major LSA manufracturer is planning on using this type of battery in a new model.
