The self-heating function will be auto activated by the BMS when the battery is connected to a charger at -20℃to 5℃. The heating will be stopped when the temperature has reached 10℃, and then the battery will be normally charged.
【4000+ CYCLES LIFETIME & UPGRADE BMS】The built-in heating pads of the Ampere Time Self-Heating battery will change the battery inside cells temperature and maintain the temperature of the cells between 5℃ to 10℃, so it will not affect the battery life and enables protecting the battery cells when charging in cold weather. Additionally, the battery used the superior automobile grade cell and reliable BMS system with a low discharge rate, which enables provide 4000+ cycles & a 10-year lifetime.
【Max. 40.96kWh CAPACITY EXPANSION & 1/3 SMALLER WEIGHT】Our LiFePO4 batteries can be connected in parallel and series for larger capacity and voltage. Allow being extended up to 4 in series and 4 in parallel (Max 4S4P) to get more capacity (Max 800Ah) and higher voltage (24V, 36V, 48V). Meanwhile, Ampere Time 12V 200Ah LiFePO4 Battery is only about 48.28lb which is smaller and 1/3 the weight of the lead-acid battery at the same capacity, and it’s convenient for you to remove and place it.
