FAQs
Unfortunately, no. The Humsienk 12V 314Ah Mini LiFePO4 battery is a deep cycle battery and can only be used as a power supply battery, not as a starting battery.
Humsienk 12V 314Ah Mini LiFePO4 battery is engineered for high-capacity supply. It has a 314Ah capacity and 4019Wh energy, ideal for your RVs, home storage, marine usage, and more.
LiFePO4 lithium battery's runtime depends on multiple factors, including the power consumption of the devices it's powering, depth of discharge (DoD), temperature, battery age and condition, internal resistance, inverter efficiency etc. But the following formula based on power consumption and battery capacity can help you estimate runtime:
Runtime (hours) = (Battery Capacity (Ah) x Voltage) / (Load (Watts) x Inverter Efficiency (if applicable))
Example Calculations:
Load: 100W, Inverter Efficiency: 90%
Runtime = (314Ah x 12.8V) /(100W x 90%) = 44.66 h
Humsienk 12V deep discharge batteries support 3 Charging Ways: LiFePO4 Battery Charging, Solar Charging, Generator/ Alternator Charging. The charging mode needs to be set to LiFePO4 mode, and the charging voltage needs to be set to 14.6V.
Avoid routinely charging to 100%. When charging, please choose a LiFePO4 charger or select the LiFePO4 mode and ensure the correct charging voltage 14.6V.
Under ideal sunlight conditions, a 400W solar panel can typically charge a 12V 314Ah LiFePO4 lithium battery in about 10 - 12 hours.
Supports multiple batteries connected in series or parallel.
- Maximum Batteries in series: 4
- Maximum Batteries in parallel: 4
- A total energy of batteries in 4 series and 4 parallel: 64.3kWh
Note: It is recommended to use batteries from the same batch and model.
Cycle life: Over 6,000 cycles (80% depth of discharge), up to 10 years.
Warranty: 5 years.
Our Humsienk 12V 314Ah Mini LiFePO4 lithium battery offers the following advantages:
- Smaller size, taking up approximately 30% less space.
- Lighter weight, making it easier to handle and install.
- Uncompromising performance, maintaining 12V 314Ah capacity.
- Ideal for RVs, boats, or energy storage systems where space is limited.
Yes, but only after removing or isolating the AGM batteries. Mixing LiFePO4 and AGM is not recommended.
It has low-temperature protection built into the BMS, preventing unsafe charging below 0°C and ensuring safe discharge down to -20°C.
You can restore it by simply charging it with a lithium-compatible charger with activation function.
