【⚡ Pre-sale】WattCycle 12V 314Ah Mini Super LiFePO4 Battery with Bluetooth & Active Balance

The difference between 1A, 2A, and 3A active balance lies in the maximum current (amperage) they can use to transfer energy between battery cells.

In essence, a higher amperage rating means the active balancer can correct imbalances more quickly and handle larger cell capacities more effectively. All types use non-dissipative energy transfer methods, meaning they are more efficient and generate less heat compared to passive balancing systems.

If the balancing switch is on, balancing will begin when the maximum cell voltage differential in the battery pack exceeds this value and will end when it falls below this value.

For example, if you set the balancing start voltage differential to 10mv and the balancing stop voltage differential to 5mV, balancing will begin when the cell voltage differential exceeds 10mV and end when it falls below 5mV.

The recommended balancing start voltage differential is 0.005V for cells over 50Ah, and 0.01V for cells under 50Ah.

When the lowest cell voltage is below the set value of 2000mV, active balancing will not begin, even if the cell voltage differential exceeds the set value. The balancing current represents the continuous current used to discharge the high-voltage battery and charge the low-voltage battery during energy transfer. The maximum balancing current represents the maximum current during energy transfer, which does not exceed 3A.

Active balancing is a cell management technique that moves charge from higher-voltage cells to lower-voltage cells, keeping every cell in the pack at a similar state of charge instead of simply shedding excess energy as heat. So your battery won't get hot as soon as you start using it, like before.

At a continuous 3A rate, this balancing is strong enough to correct cell drift during normal use and to support higher, safer charge currents.

Practically, active balancing means you retain more usable capacity over the life of the battery pack, accept faster and fuller charging without hitting early cutoffs, and experience slower capacity fade so the system delivers steady performance year after year.

Without active balancing, individual cells drift to different States of Charge (SoC) over repeated cycles, which means the battery’s usable energy is effectively capped by the weakest cell; that mismatch forces earlier charge or discharge cutoffs, limits safe charge rates, reduces usable capacity, and accelerates overall ageing.

Absolutely. LiFePO4 is the most stable lithium chemistry on the market. WattCycle cells are UL-certified and housed in an IP65-rated case. Our internal BMS guards against:

• Over Charge & Over Discharge
• Under Voltage & Over Voltage
• Over Current & Short Circuits
• High Temperature
• Low-temperature Cut-off

No, the 12V 314Ah Super Lithium Battery cannot start a car. However, it can be used as an auxiliary battery for cars.

Unfortunately not!

However, our 12V 314Ah Mini LiFePO4 Battery with Bluetooth is ECE R10 certified (E57*10R06/03*1833*00).

The WattCycle 12V 314Ah Mini Super LiFePO4 Battery is very powerful and suitable for most common inverters.

• Continuous power: It can deliver 2560W of continuous power. This is enough to continuously operate most camping and household appliances, such as kettles (1000-1500W), coffee makers, or even small air conditioners.
• Peak power: Thanks to our powerful 200A BMS, it supports a peak power of up to 5632W (220A for 10 seconds). This provides ample reserves to easily start devices with high starting currents, such as microwaves or refrigerators/compressors.

In short, the 12V 314Ah Mini Super LiFePO4 Battery is ideal for inverters up to approximately 2500W-3000W in continuous operation and can also handle larger loads for short periods.
