FAQ
What makes this 320Ah battery different?
This 12V 320Ah LiFePO4 battery provides 4096Wh of usable energy, compared with about 3840Wh from a 12.8V 300Ah battery. It also includes Bluetooth app monitoring, a built-in 200A BMS, low-temperature protection, and expandable 4P4S support for larger energy storage setups.
Does it support Bluetooth monitoring?
Yes. The built-in Bluetooth function lets you monitor battery voltage, capacity, current, temperature, and operating status from your smartphone.
What charger should I use?
We recommend using a 14.4V–14.6V LiFePO4 charger. For this 320Ah battery, a 20A to 40A charger is commonly suitable, while a higher-current charger can reduce charging time if supported by your system.
How many batteries can I connect together?
This battery supports up to 4P4S connection, allowing expansion for 12V, 24V, 36V, or 48V systems when properly configured.
Is this battery a starting battery?
No. This LiFePO4 battery is designed for deep-cycle energy storage applications such as RVs, marine use, solar systems, off-grid setups, and backup power. It is not intended to be used as an engine starting battery.
