Green Cell CUBE LiFePO₄ 12.8 V 50 Ah (640 Wh) – Leisure/Solar Battery

Compact, safe and built to last.
The Green Cell CUBE 50 Ah LiFePO₄ is a lightweight 12.8 V battery for campers, boats, golf carts, foodtrucks and small off-grid systems. With stable LiFePO₄ chemistry, an intelligent BMS and IP54 splash resistance, it delivers dependable power in mobile and outdoor environments.

Highlights

• Long service life: > 3,000 full cycles with > 70% capacity remaining — over 10 years of typical use.

• High usable power: continuous discharge capability of 1C (≈ 50 A) for fridges, pumps, 12 V inverters and other onboard loads.

• Safety first: integrated BMS guards against over/under-voltage, over-current and temperature issues; low-temperature charge protection (< 0 °C) included.

• Weather-ready: IP54 protection against splashes and dust for marine and outdoor use.

• Scalable system design: series connection up to 4 batteries (48 V); parallel connection to increase capacity (use identical, new units).

• Lightweight vs. lead-acid: up to 3× lighter at the same capacity; low self-discharge keeps it ready after storage.

• Peace of mind: 36-month warranty from the manufacturer.

Recommended applications

• Campervans/motorhomes (house battery), foodtrucks & service vans

• Small boats/yachts, trolling motors* and onboard 12 V systems

• Golf carts, light mobility devices*

• Off-grid cabins, garden offices, security/monitoring equipment, UPS backup

* Always verify voltage and current requirements for your specific device.

Charging & use guidelines

• Use a LiFePO₄-compatible charger or inverter/charger (CC/CV profile).

• For multi-battery systems (series or parallel), use identical, new batteries balanced to the same voltage and follow proper cable sizing and fusing practices.

• Operating window: discharge down to −20 °C, up to +60 °C; do not charge below 0 °C (built-in protection helps prevent this).
