The auto self-heating function will be activated by the BMS when the battery is connected to a charger at -20â to 5â (-4â to 41â). The heating will be automatically activated once the charging temperature drops below 0°C(32°F). It will stop when the battery temperature reaches 5â (41â).
These two series primarily address the charging issues of LiFePO4 lithium batteries in cold weather. The main difference between the Low-Temperature series and the Self-Heating series lies in the presence of an automatic Battery Management System (BMS) heating module. The Self-Heating series allows the battery to self-warm without any action required from the user while charging.
However, the LiTime cold weather batteries will automatically cut-off the charging when the temperature is below 0â (32â), and it requires you to take some measures, such as placing the battery in a warm indoor environment, to warm it up to 5â (41â) and restore charging capability. Read on LiTime Low-Temperature Batteries VS Self-Heating Series for more information.
Yes. The LiTime 12V 200Ah self-heating LiFePO4 lithium battery can discharge if it has power while heating. However, we don't recommend discharging during the heating process, as it may harm the performance and lifespan of the battery.
External heating only heats the casing and does not heat the battery cells. In conditions of -20°C, after external heating for two hours, the battery cells temperature rise to 5°C, but the lead-acid casing temperature has risen to 70-80°C.
Therefore, it is not recommended to externally heat the battery, as the actual cell temperature cannot be determined at this time.
Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. LiTime lithium cells are UL certified for the highest safety and sustainability standards.
All LiTime LiFePO4 batteries come with an internal Battery Management System which protects against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during charge and discharge, and short-circuit protection â protects battery cells from damage. Additionally, LiTime LiFePO4 Lithium batteries have been tested to be free from the risk of fire, and electric shock in harsh environments.
No. LiTime LiFePO4 lithium deep cycle batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.
If you need the marine starting batteries, visit LiTime 12V 20Ah Marine Cranking or 12V 140Ah Dual Purpose battery to choose.

1. Using Solar Panels
The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 800W solar panels. It may take more than one day to fully charge the battery by â„800W solar panels since the duration and intensity of light would be a great factor for their charging efficiency. Besides solar panels, there are 2 more ways to charge.
2. Generator/Alternator
If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: â 40A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ⥠100A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.
3. LiFePO4 Smart Chargers
To charge 12V battery, it is recommended to use 14.6V battery charger. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: â 40A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ⥠100A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

LiFePO4 lithium battery charging temperature range is 0â to 50â / 32â to 122â, charging LiFePO4 battery under freezing point would damage the battery cell. So it's not recommended to charge in cold weather.
If you live in the area where winter is long, it's recommended to use LiTime cold weather batteries which include the low-temperature charging protection and will automatically cut the battery charging off when the cell temperature is lower than 32â, thus preventing the battery cells from damage when charging under the freezing point.
It is recommended to store LiTime LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10âïœ35â (50âïœ95â), 45%RHïœ75ïŒ RH
