FAQs
Unfortunately, no. The Humsienk 12V 310Ah deep discharge battery is a deep cycle battery and can only be used as a power supply battery, not as a starting battery.
Humsienk 12V 310Ah LiFePO4 battery is engineered for high-capacity supply. It has a 310Ah capacity, and 3968Wh 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 = (310Ah x 12.8V) /(100W x 90%) = 44.09 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.
When properly maintained, the 310Ah deep discharge battery can last up to 10 years. Humsienk provides 5 years battery warranty.
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 310Ah battery in about 10 - 12 hours.
Unfortunately no! The Humsienk deep discharge batteries can be safely charged between 0ºC to 55ºC.
Maximum Batteries in series: 4
Maximum Batteries in parallel: 4
A total energy of batteries in 4 series and 4 parallel: 63.488 kWh
If your system voltage is fixed at 12V, we would recommend purchasing a single 12V 310Ah LiFePO4 Lithium battery. This saves more space and cumbersome cable connections, and the charging efficiency is also higher than three parallel battery packs.
