FAQs
Unfortunately, no. The Humsienk 12V 300Ah LiFePO4 bluetooth battery is a deep cycle battery and can only be used as a power supply battery, not as a starting battery.
Humsienk 12V 300Ah deep cycle LiFePO4 bluetooth battery is engineered for high-capacity supply. It has a 300Ah capacity and 3840Wh 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 = (300Ah x 12.8V) /(100W x 90%) = 42.66 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.
No, the Bluetooth module consumes very little power and has almost no impact on battery life.
