My winter ride is about an hour each way and the temps get down to 0F on occasion - with this system and in these conditions, I've never had an issue with battery life.
I've had mine for about 6 years now and really like it too. The battery life has been decreasing with time, but it's still good enough to get me through my longer rides and it doesn't bother me to charge it more often now.
