I have a general question about charging LiPo batteries. I just bought a new 2s LiPo that says it can be charged at 3C, or 15 amps. The LiPo charger that I am currently using will only charge up to 5 amps. Are there any disadvantages to charging at 5 versus 15 amps, other than taking longer to charge the battery?

No one has shown evidence that I've seen that reduced charge rates increases or extends lipo cycle life or provides any other measureable benefits.

I upgraded charger equip just to take advantage of this. I'm buying 5C capable lipos and will be charging them at 25amps - enjoying 12-13min charges.
