LiTime 12V 200Ah Self-Heating LiFePO4 Lithium Battery with 100A BMS, Low Temperature Protection

A: When deciding whether to get a self-heated battery. We've had customers use this battery when skiing ice fishing or doing other various winter activities. You can use and discharge LiTime lithium batteries in cold temperatures but a self-heated battery might be what you want if you plan to charge in the cold.

A: The auto self-heating function will be activated by the BMS when the battery is connected to a charger at -20℃ to 5℃ (-4℉ to 41℉). The heating will stop when the battery temperature reaches 10℃ (-4℉).

A: No. The charging will start after the lithium battery heat itself to 10℃ (50℉).

A: 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.

A: 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 – 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 batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

Yes, you can charge LiTime LiFePO4 lithium batteries with solar panels. You should size your charge controller based on the voltage and current output of your solar array setup. That will ensure that your charge controller can process and regulate the power coming from your solar panels. Take a 24V MAX. 22 amps output solar system as example. You would need a solar charge controller that can handle 24 volts and 27.5 amps (125% of your max current output).

LiFePO4 batteries can safely charge between 32°F to 113°F (0°C to 45°C). LiTime 12V 100Ah Smart LiFePO4 batteries include the low-temperature charging protection which will automatically cut the battery charging off when the cell temperature is lower than 32℉, thus preventing the battery cells from damage when charging under the freezing point. If necessary (not recommended), you can push the low-temp protection button twice, then the BMS would allow your battery to charge under the freezing point for emergency use.

How do I store LiTime LiFePO4 lithium batteries?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: 10℃～35℃ (50℉～95℉），45%RH～75％RH
