FAQs Can 12V 314Ah Mini LiFePO4 lithium battery be used as a starting battery?
No, Humsienk 12V 314Ah Mini LiFePO4 lithium battery is a deep-cycle battery designed for energy storage and not for the high, short-burst current required for starting an engine.
Are Humsienk LiFePO4 lithium batteries safe?
All Humsienk LiFePO4 lithium batteries have built-in powerful BMS, which has multiple protections such as overvoltage, overcurrent, extreme temperature, short circuit, etc.
What are the dimensions and weight of this 12V 314Ah Mini LiFePO4 battery?
The dimensions are 382 x 193 x 249.5 mm, which is smaller than LiFePO4 batteries with a capacity of over 300Ah on the market. The weight is 28 kg.
How many amp hours does 314Ah Mini LiFePO4 lithium have?
Humsienk 12V 314Ah Mini LiFePO4 lithium battery is equipped with 4 x 3.2V 314Ah EV grade A+ prismatic LiFePO4 cells and 100A BMS, delivering massive 4019.2Wh of usable energy and 1280W output power. Ideal for high-demand applications, LiFePO4 for RVs, Solar & Marine.
How to check the capacity of the 12V 314Ah Mini LiFePO4 lithium battery?
For Bluetooth Version: Built-in Bluetooth 5.0, can be monitored via the HumSienk Smart BMS App. Bluetooth Guide.
How many hours will the 12V 314Ah Mini LiFePO4 lithium battery at 500 Watts last?
Approximate 8 hours. Assumed close to 100% efficiency, 500 Watts divided by 12.8 Volts is about 39A. If you run the battery dead 314Ah divided by 39A is about 8 hours.
How to charge this 314Ah Mini LiFePO4 lithium battery?
There are three general charging methods: AC-DC LiFePO4 charger, solar panel charging and DC generator charging. Charging Voltage: 14.4V-14.6V
Recommended Charge Current: 60A (0.2C)
Can I charge Humsienk LiFePO4 lithium batteries in cold weather (under freezing temperatures)?
All Humsienk LiFePO4 lithium batteries are charged within a range of 0°C to 55°C and feature low temperature cut-off protection. When the ambient temperature is below 0°C, the BMS will cut off to protect the battery. Charging in freezing temperatures will damage the battery cells.
Can I charge the 314Ah Mini LiFePO4 lithium battery with a normal charger?
No, this is not recommended. All Humisenk LiFePO4 lithium batteries are LiFePO4 deep cycle batteries. Using a charger not specifically designed for LiFePO4 batteries may result in overcharging and damage to the LiFePO4 battery cells.
What is the maximum number of Humsienk 12V 314Ah Mini LiFePO4 lithium batteries connected in series or parallel?
Humsienk 12V 314Ah Mini LiFePO4 lithium battery supports up to 4 series and 4 parallel connections, which means that 16 12V 314Ah Mini LiFePO4 lithium batteries can form a 48V 1256Ah battery system. ⚠️ Critical Connection Requirements Same brand: The batteries need to be of the same brand, as the cells and BMS of other brands of batteries may be different from those used by Humsienk.
Same Battery Model: Using the exact same battery model with the same voltage (V), capacity (Ah), and BMS rating (A).
Purchased in the last three months: Ensuring they are from the same manufacturing batch for balanced performance.
Tips: Before connecting batteries in series or parallel, each battery needs to be fully charged.
Can I just replace a lead acid battery with this 12V 314Ah Mini LiFePO4 lithium battery?
Sure! Switching to LiFePO4 lithium batteries requires some planning to ensure it works seamlessly with your existing lead-acid battery system:
1. Voltage compatibility
2. Capacity and runtime matching
3. Dimensions and connection terminals match
And you need to consider whether the charging device should match the LiFePO4 battery.
