Compact, safe and built to last.
The Green Cell CUBE 12.8 V 125 Ah LiFePO₄ delivers dependable 1.6 kWh energy for motorhomes, boats, food trucks and small off-grid systems. It’s up to 3× lighter than comparable lead-acid, offers >3,000 cycles (≥70% capacity), and includes an intelligent BMS, IP54 splash resistance and low-temperature charge protection. 

Highlights

• Long service life: up to 3,000 cycles @100% DoD and 5,500 @60% DoD for 10+ years of typical use.

• High usable power: 125 A continuous discharge with 150 A peak for starting loads and inverters. 

• Smart protection: integrated BMS, charging blocked below 0 °C, and IP54 ingress protection. 

• Scalable system design: connect in series up to 4 units (48 V) or parallel (unlimited) with identical new batteries. 

• Lightweight vs. lead-acid: LiFePO₄ chemistry cuts weight by up to 3× while maintaining a flat 12 V voltage curve.

Recommended applications

• House battery for campers/motorhomes; food trucks & service vans

• Small boats/yachts & 12 V onboard systems

• Golf carts and light mobility equipment*

• Off-grid cabins, garden/home offices, security/monitoring, UPS/inverter backup
  * Always verify device voltage and current requirements.

Charging & use

• Use a LiFePO₄-compatible charger or inverter/charger with CCCV / IU profile. Continuous charge current: 50 A. 

• For series/parallel banks, use identical, new units with the same voltage (ΔV < 0.3 V); size cables/fusing correctly and install by a qualified professional. 

• Operating window: discharge −20 °C … +60 °C; charge 0 °C … +45 °C. Voltage range: 9.2–14.6 V.
