I was looking in the owners manual for a new Icom handheld that uses a LiIon battery. I was surprised to see that the handheld locks itself in low power mode (0.5W) when the temperature is below 0C to protect the battery. I had a look for performance data for LiPo packs at low temperatures and all I have been able to find so far is lots of RC modelers regurgitating other peoples’ “sage advice” about the lack of performance form their packs when it’s cold but no hard performance curves. Now RC modelers hammer their batteries compared to us so it’s no surprise that they show up the worse performance of batteries when it’s cold.
I was wondering if those who have been using LiPos for some time have actually experienced poor performance when it’s cold to such an extent that it has affected their operation. Also if anyone else with a modern handy using Lithium battery technology has noticed low temperature problems.
