WattCycle 12V 314Ah Mini Bluetooth lithium leisure battery has an internal 200A BMS(Battery Management System), which ensure a max 200A(1C) continuous discharge/charge current. Made of EV-grade A+ cells, it can store 4.01kWh energy, providing enough energy during your motorhome trip.
The external IP65 waterproof rating makes the battery fearless of salt environments, and the internal metal frame ensures that the battery is safe even in bumpy environments.
With high and low temperature cut-off protection, it keeps your essentials powered through the cold and heat. When the battery is in use, the BMS initiates protection when the temperature drops below -25°C to -15°C. When the temperature rises from 5°C to 15°C, the battery continues to discharge.
WattCycle 12V 314Ah Mini Smart Battery can be placed sideways. Its dimensions of L384 x W194 x H248 mm are extremely suitable for the narrow space of the motorhome yet provide much more usable energy.
Whether you’re preparing a powerful energy system in your campervan, storing energy for your boat on open waters, or setting up an outdoor portable power station, this battery offers complete flexibility in installation.
It can be safely mounted upright, sideways, or flat, ensuring stable performance and reliable power delivery in any position. No matter the environment, it adapts perfectly to your space and keeps your energy flowing without compromise.
WattCycle 12V 314Ah Mini lithium leisure battery has a unique internal design. There is a metal frame inside to enhance the stability of the battery. Built with braided flexible copper wires, it can deliver 50% more power and run 30% cooler with the aluminum colling fins.
WattCycle's flagship 12V 314Ah Mini Bluetooth lithium battery redefines portable power with its space-saving dimensions (L384 × W194 × H248mm, L340mm without the handles) and remarkably light 27kg frame. Delivering 2560W output and 4019Wh capacity, it outperforms traditional setups - replacing three bulky lead-acid batteries (87kg) that offer just 1800W/1800Wh. It's a smarter and more efficient energy solution for modern needs.

Yes. Our 200 A BMS protects against charging or discharging in unsafe temperatures.
We recommend using a WattCycle LiFePO4 battery charger, which is specifically designed to meet the unique charging needs of LiFePO4 batteries. Alternatively, you can also charge the battery using photovoltaic solar panels through MPPT or use an inverter with a built-in AC to DC charging function.
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:
Yes—our 12V 314Ah LiFePO4 Battery is designed for seamless solar charging. Simply pair it with an MPPT charge controller and a 1.200W PV array to top up in one sunny day (≈4.5 hrs of peak sun).
Optimal Setup: A 1.200W solar panel bank feeding an MPPT regulator ensures efficient charging of your 12V 314Ah solar battery.
Charge Profile: MPPT controllers adjust voltage/current to maintain the ideal 14,2V – 14,6V range, protecting cell health and maximizing cycle life.
Scalable: Whether you’re building out 12V 314Ah batteries for solar panels in parallel or keeping it simple with one pack, the WattCycle system adapts—no special wiring or firmware tweaks required.
1. Recommended Storage Conditions
2. Recommended Charge Level During Storage
LiFePO4 batteries should be stored at a partial state of charge (SOC) between 50% and 80%.
Why Avoid Full Charge/Discharge?
