The battery heaters are self consuming. All of these quality drop in LiFePO4 batteries have low temperature cutouts. So the BMS will not allow your charging system to charge the battery below this temperature setting. There is no problem with discharging at low temperatures but generally low temperature cutouts are set at or below freezing depending on the brand and it's BMS.
