Are you in a garage? As long as you have 30+ amps of 240v, you are fine charging in winter. It will spend 5-15 minutes warning the pack (and show only a little charge rate) and then kick into your full charge rate. The only time you are screwed is in like 15-20 amp 120V, it takes nearly all the power to keep the battery warm so almost nothing left to charge. If it weren’t for winter I likely would have kept only a 120 in my garage as that is plenty for summer charging at home.
