Sounds like something is intermittent. I don't think most boost chargers 
would hurt the FI, but just in case, what is the voltage across the battery 
when you have your charger on boost? I can't imagine that anything less 
than 20 V would hurt anything, and 20 V would be awfully high for a charger.
