The Ultra-thin Slim 2.5kWh 12V 200Ah Lithium Iron Phosphate (LiFePO4) Battery Pack is designed for modern RV, camping, and yacht power systems where space efficiency, safety, and long-term reliability are critical.
With a nominal energy capacity of 2.56kWh (12.8V × 200Ah), this deep-cycle lithium battery delivers stable and long-lasting power for off-grid living, marine systems, and mobile energy storage. Its ultra-slim structure allows installation in narrow compartments, under seats, inside cabinets, or confined marine battery rooms where traditional batteries cannot fit.
Built with premium Grade-A LiFePO4 cells and an integrated Smart Battery Management System (BMS), this battery ensures maximum performance, safety, and durability in demanding environments.
Unlike traditional bulky batteries, this model features a slim and compact housing, making it ideal for:
RV under-seat installation
Caravan storage compartments
Yacht battery rooms
Camper van interior builds
Narrow solar storage cabinets
The reduced thickness allows flexible mounting options while maintaining full 200Ah capacity.
Nominal Voltage: 12.8V
Nominal Capacity: 200Ah
Total Energy: 2.56kWh
This provides sufficient energy to power:
Refrigerators
Lighting systems
Water pumps
TVs and electronics
Small air conditioning systems (with inverter)
Marine navigation equipment
The battery supports deep discharge while maintaining stable voltage output throughout the cycle.
The built-in Battery Management System provides:
Overcharge protection
Over-discharge protection
Overcurrent protection
Short-circuit protection
Temperature protection
Automatic cell balancing
The BMS continuously monitors each cell to ensure safe operation and maximize lifespan.
Optional upgrades may include:
Bluetooth monitoring
RS485 / CAN communication
LCD voltage display
At 80% Depth of Discharge (DOD), the battery can achieve:
4000–6000 cycles
8–10 years service life under normal use
Compared to traditional lead-acid batteries (300–500 cycles), this lithium battery dramatically reduces replacement costs and long-term investment.
Compared with a 200Ah AGM battery, this LiFePO4 version:
Is up to 50% lighter
Provides nearly 100% usable capacity
Maintains high efficiency (>95%)
Has very low self-discharge rate
This makes it ideal for mobile and marine applications where weight matters.
Lithium Iron Phosphate (LiFePO4) technology offers:
Excellent thermal stability
No fire or explosion risk under normal use
No acid leakage
No toxic gas emission
Environmentally friendly materials
It is one of the safest lithium battery chemistries available today.
This slim 12V 200Ah lithium battery is perfect for:
✔ RV and Camper Vans
✔ Caravans
✔ Yachts and Boats
✔ Marine Electronics Systems
✔ Off-Grid Solar Systems
✔ Camping Energy Storage
✔ Mobile Power Stations
✔ Emergency Backup Power
