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 it in the cold.

There are 2 heating pads built in. 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℉).

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 low-temperature charging protection series like LiTime 12V 100Ah TM & LiTime 12V 230Ah will automatically cut-off the charging when the temperature is below 0℃ (32℉), and it requires you to take some measures, such as placing the battery in a warm indoor environment, to warm it up to 5℃ (41℉) and restore charging capability.

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

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.

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 for example. You would need a solar charge controller that can handle 24 volts and 27.5 amps (125% of your max current output). Besides solar panels, there are 2 more ways to charge.

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.
