OK so you recommend insulation to keep them cool?  For me, insulation 
is more likely to result in higher temperatures in summer.  In 
winter, an insulated space is obviously ideal for performance 
depending on the kind of winter (which seems to be a variable these 
days).  In summer, insulation directly on the battery seems unlikely 
to keep them cool.  On charge they will definitely need a temperature 
sensor and will be likely to get hotter than ambient if insulated.
