Upon receiving your battery, it might have a low state of charge (SOC) due to transportation and storage. To ensure optimal performance, please charge the battery immediately to prevent over-discharge.
For batteries equipped with Bluetooth functionality, they may arrive in a powered-off state, displaying a terminal voltage between 3V and 5V, which prevents connection to your smartphone. This is a standard shipping practice, akin to how mobile phones are shipped powered off, to minimize self-discharge and extend battery lifespan.
To activate the battery, you can use either an AC-DC lithium battery charger or an MPPT solar charge controller to charge it for 3 to 10 seconds. After this brief charging period, the battery should function normally.
If you intend to store the battery for an extended period, it's recommended to charge it to approximately 50% SOC and perform maintenance every three months. This practice helps preserve the battery's functionality and performance over time.
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℉).
No. The charging will start after the lithium battery heats itself to 10℃ (50℉).
Yes. The self heating lithium battery can safely charge between -20℃ to 50℃ ( -4℉ to 122℉). The built in self-heating pad will automaticlly start heating the battery.
LiFePO₄ (Lithium Iron Phosphate) batteries are widely considered to be one of the safest lithium battery types available today, with excellent thermal and chemical stability that significantly reduces the risk of overheating and fire. LiTime's LiFePO₄ batteries have passed a number of international certifications including UL, FCC, CE, RoHS and UN38.3, ensuring their quality and safety.
In addition, all LiTime batteries have a built-in battery management system (BMS), which provides over voltage, under voltage, over current, over mild short circuit protection during charging and discharging to prevent battery damage. After rigorous testing, LiTime's LiFePO₄ batteries also performed well under extreme conditions without safety incidents such as fire or explosion.
