It's impossible to judge how much a single complete discharge would hurt a particular battery bank. If left discharged for a period, damage is greaty increased. If the battery is old it could spell the end. In cold weather, the damage is likely less pronounced. You can likely get some figures from battery mfg sites....seems like I read about 3% or 5% might be a rough estimate of power loss due to a single complete discharge...
