WattCycle 16kWh 48V 314Ah LiFePO₄ Battery FAQs
This 51.2V 314Ah floor-standing LiFePO₄ battery provides 16.07kWh of energy storage and is designed for off-grid homes, farm properties, workshops and professionally configured backup power systems.
One battery stores approximately 3.14 times the energy of a 5.12kWh battery, reducing the number of batteries, cables and parallel connections required. It is a practical choice for customers who need higher overnight capacity in one cabinet.
Runtime depends on the combined power consumption of the connected appliances.
As a simple theoretical guide:
- A 1,000W average load: approximately 16 hours
- A 2,000W average load: approximately 8 hours
- A 4,000W average load: approximately 4 hours
Actual runtime will be lower after allowing for inverter efficiency, battery settings, temperature and system losses.
Estimated runtime = usable battery energy ÷ average load.
Send us your daily electricity usage and essential appliance list if you need help selecting the correct battery capacity.
The battery supports a standard charge and discharge current of 150A, equivalent to approximately 7.68kW at 51.2V. Its powerful 300A BMS can support up to approximately 15.36kW of DC output, subject to the inverter, cabling and complete system design.
Actual AC output and appliance start-up capacity are determined by the inverter. High-demand appliances such as air conditioners, pumps, heaters and power tools must remain within both the battery and inverter limits.
An inverter is not included. This is a 51.2V DC battery and requires a compatible 48V/51.2V inverter-charger to power standard AC appliances.
The battery supports CAN and RS485 communication, but this does not mean it works with every inverter model. Compatibility depends on:
- Inverter voltage range
- Battery charging settings
- CAN or RS485 communication protocol
- Inverter firmware
- Communication cable pin configuration
Please send us your inverter brand and exact model number before ordering so that compatibility can be checked.
Grid connection and rebate eligibility are not automatic. They depend on the complete battery and inverter combination, the current Clean Energy Council approved product lists, network requirements and installation by an appropriately accredited professional.
CE, IEC, FCC, EMC, RoHS or UN38.3 documentation does not by itself confirm Australian grid-connection or government-rebate eligibility.
If you intend to use this battery in a grid-connected system, export electricity, join a VPP or claim a rebate, ask your installer to verify the exact battery and inverter models before purchasing. It is primarily suited to compatible off-grid, farm, workshop and professionally designed backup applications.
The standard charging current is 150A, with a maximum supported current of approximately 305A.
Under ideal conditions:
- 150A charging: approximately 2.1 hours
- Maximum-current charging: approximately 1 hour
Actual charging time may be longer because of charging losses, temperature, state of charge and charger limitations. One-hour charging requires a compatible high-power inverter-charger and correctly sized electrical protection.
The recommended charging temperature is 0°C to 55°C, while the discharge range is -20°C to 60°C.
The battery measures 450 × 240 × 880 mm and weighs approximately 115kg. Swivel wheels make positioning easier, but the battery should be securely restrained after installation and should not be treated as a portable power station.
Up to 20 matching batteries can be connected in parallel, expanding storage capacity from 16.07kWh to approximately 321kWh. Parallel systems require matching batteries, balanced cable lengths, suitable busbars, DC protection and a compatible inverter.
Due to the battery’s weight and high current capability, professional system design and installation are strongly recommended.
1. Cell Overcharge Protection and Recovery
When the voltage of any cell is higher than the set value of the cell overcharge voltage, and the time of duration reaches the cell overcharge delay, the system enters the overcharge protection state, the charging MOS will turn off, and the battery cannot be charged.After the cell overcharge protection, when the voltage of all cells drops below the cell overcharge recovery value, the overcharge protection state is released. It can also be released by discharge.
2. Overall Overcharge Protection and Recovery
When the overall voltage is higher than the overall over-voltage set value, and the time of duration reaches the overall overcharge delay, the system enters the overcharge protection state, turns off the charging MOS, and cannot charge the battery.When the overall voltage drops below the recovery value of the overall over-voltage protection, the overcharge protection state is released, and it can also be released by discharge.
