12V 300AH Deep Cycle LiFePO4 Lithium Battery(Self-Heating & APP Monitoring)

Features

Details from the VATRER POWER Amazon listing:

• 【Self-Heating Feature】After charger connection and with charging current exceeding 10A, the BMS continuously monitors battery temperature. Should the temperature drop below 0°C (32°F), the auto-heating mode activates, drawing power from the charging current for the internal heating film. The heating system deactivates instantly, and standard charging resumes when the temperature rises to 5°C (41°F).
• 【BMS Protection】To keep the battery safe, durable and working at its best while charging and discharging, the integrated BMS offers a full set of protective functions. It includes protection against overcharging, over-discharging, overcurrent, short circuits, extreme temperatures, abnormal voltage, along with intelligent cell balancing.
• 【Wide Application】Boasting large capacity and steady 12V DC output, this 12V 300Ah lithium battery is ideal for devices needing long-duration power. It perfectly fits RVs, campers and marine vessels to run lights, microwaves, refrigerators and other onboard appliances. Additionally, it works well for off-grid solar setups and household backup power systems. Paired with an inverter, it can supply power to computers, TVs, mobile phones and more, delivering consistent and reliable power round the clock.
• 【APP Monitoring】Once you install the dedicated APP, you can keep track of core battery data in real time, such as remaining capacity, voltage, current, power, fault alerts and temperature. This allows you to fully and clearly check the battery operating status.
• 【3 Charging Ways】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 golf cart batteries when connected in series.
• ATTENTION: 1. READ THE OPERATION MANUAL BEFORE USE 2. DO NOT TOUCH HOT SURFACE
