【Self-Heating Function】After connecting the charger, if the charging current exceeds 10A, the BMS will begin monitoring the battery temperature. When the battery temperature drops below 32°F (0℃), the BMS will automatically activate the self-heating function, at which point the charging current will power the heating film inside the battery. Once the battery temperature rises back to 41°F (5℃), the BMS will immediately turn off the heating function and resume the normal charging process.
【APP Monitoring】After downloading the APP, users can monitor key battery parameters in real time, including capacity, voltage, current, power, battery error status, and temperature, providing a more comprehensive and intuitive understanding of the battery's operation.
【BMS Protection】The protection functions of a Battery Management System (BMS) are primarily designed to ensure the safety, lifespan, and performance of the battery during charging and discharging. Common protection features include: overcharge protection, over-discharge protection, overcurrent protection, short-circuit protection, over-temperature protection, low-temperature protection, cell balancing, and overvoltage/undervoltage protection.
【Wide Application Scenarios】 The 12V 300Ah lithium battery, with its large capacity and stable 12V DC output, is widely used in various applications requiring long-term power supply, including daily power needs in RVs, campervans, and boats for lighting, microwaves, refrigerators, etc. It is also suitable for off-grid solar systems and home backup power supplies, providing power to devices such as computers, televisions, and mobile phones via an inverter, providing users with continuous and stable power support.
【3 Charging Methods】12V 300Ah lithium battery can be charged using a 14.6V lithium charger, solar power, or a generator. If you use our 14.6V 70A lithium battery charger, it will take approximately 4.3 hours to fully charge the battery. If you use solar charging (with a power output of 800W or more), it will take approximately 4.8 hours to fully charge the battery.
【Important Note】 Not suitable for use as a starting battery or golf cart battery.
