Yes you will need a charger that either has a A123/LiFePO4 setting or adjustable CC/CV. If you are creative you may be able to charge on other settings too if. I've heard of "resistor" charge method, but it takes longer than CC/CV.
My charger that I use is a Hyperion 610i that I bought several months ago because I felt that it was a really good charger and could charger just about anything I may use.
