I get a ton of customers who dont ride in the winter and loose battery capacity because they left their bike uncharged in a cold garage for 6 months. With the controller muake sure the area it is in is sealed. I even heard of one guy putting a sandwich bag over the controller.
LipoPo batteries shouldn't lose capacity permanently left in the cold properly charged to a storage voltage of 3.8 volts per cell, on the contrary I understood the cold should extend their lifespan. Yes a cold battery has less capacity temporarily as long as it's cold that I understand unless your customers posssibly left their batteries hooked up to the BMS and/or controller causing a battery drain? I'm also assuming le4waving batteries warm up before charging and letting batteries warm up inside before discharging/riding in cold weather.
