Looking for specific info?
Is this battery easy to install?
Yes, the GoKWh 12V 320Ah LiFePO4 battery is designed for easy installation. At 55.12 lbs with a space-saving square design, it's manageable for one person to handle. The standard M8 terminals ensure seamless compatibility with existing systems.
Can it be used in cold weather?
Yes, the GoKWh 12V 320Ah LiFePO4 battery is specifically designed for cold weather use. It can discharge normally at temperatures as low as -4°F (-20°C), making it excellent for winter outdoor applications.
The advanced BMS automatically cuts off charging below 32°F to protect the battery cells from damage, but it continues to provide power even in freezing conditions.
What devices is it compatible with?
The GoKWh 12V 320Ah LiFePO4 battery is compatible with a wide variety of devices and applications:
RV & Marine Equipment:
- RV air conditioners and electrical systems
- Boat motors and trolling motors
- Marine electronics and house batteries
Solar & Off-Grid Systems:
- Solar panel storage systems
Does it have overcharge protection?
Yes, the GoKWh 12V 320Ah LiFePO4 battery has comprehensive overcharge protection through its upgraded 200A Battery Management System (BMS).
The BMS actively protects against:
- Overcharging - prevents damage from excessive voltage
- Over-discharging - stops battery drain at safe levels
- Overload and short circuits - cuts power during dangerous conditions
- Temperature extremes - automatically stops charging below 32°F
Battery Balancing Method and Balance Current？
GoKWh 12V LiFePO4 Battery uses passive balancing to ensure cell voltage consistency:
Balancing Current: When a cell’s voltage reaches 3.2V and the voltage difference between cells exceeds 300mV, a 0.05A balancing current is applied.
Cell Selection: Cells are selected with a voltage difference of less than 5mV to ensure uniformity.
With minimal voltage variation in the 12V (4S) configuration, passive balancing ensures optimal performance and longevity.
This approach guarantees reliable and balanced power distribution for long-lasting performance
