Lithium iron phosphate batteries are happy to discharge in weather that would have you reaching for a jacket. Charging them below freezing is the limit. Plating can form inside the cell when you push current into a pack that is under 32°F, and that damage does not show up on the state-of-charge meter the same day.
What to do on a cold morning
If the cart slept outside and the battery is near freezing, drive it gently or bring it into a warmer bay before you plug it in. Do not assume the charger is smart enough to refuse. Some battery management systems block the charge. Some do not. The manual for that battery is the rule.
Heated packs
Bedrock and other makers sell heated versions for carts that are charged outdoors in a freeze. The heater warms the cells before charge current is allowed. If your cart lives in a place that freezes and you cannot charge it indoors, ask for the heated battery before you order the standard kit. Lead time is longer than a stock kit.
Tell us the climate and the cart and we will point at a standard kit or a heated one. The warranty page is where a cold-charge claim will be judged, and charging below the published range is the usual reason a claim is declined.
