The Camel Energy D135 is a high-performance 12.8V 135Ah LiFePO4 marine battery engineered for demanding marine applications. Designed with automotive-grade LiFePO4 cells, an intelligent Battery Management System (BMS), and optional Bluetooth monitoring, it provides reliable power for trolling motors, fishing boats, yachts, sailboats, onboard electronics, and off-grid marine systems.
Compared with conventional lead-acid marine batteries, the D135 delivers significantly longer cycle life, lower weight, faster charging, and maintenance-free operation, helping boat owners reduce operating costs while improving overall system reliability.
With a usable energy capacity of 1728Wh, the battery is ideal for both deep-cycle propulsion and auxiliary power applications.
- Over 4000 cycles at 80% Depth of Discharge
- Up to 10 years design life under proper operating conditions
- Significantly reduces battery replacement frequency
The integrated smart BMS continuously protects the battery against
- Overcharge
- Over-discharge
- Over-current
- Short circuit
- Cell balancing
- Temperature protection
This ensures maximum battery safety and consistent performance even in harsh marine environments.
Compared with equivalent AGM or lead-acid batteries, the D135 weighs considerably less while delivering higher usable capacity.
Benefits include:
- Easier installation
- Improved boat efficiency
- Reduced overall vessel weight
- Better acceleration for electric boats
The optional Bluetooth APP allows users to monitor battery status directly from a smartphone.
Real-time information includes:
- State of Charge (SOC)
- Battery Voltage
- Charge/Discharge Current
- Remaining Capacity
- Temperature
- Cycle Count
- Cell Voltage
No additional monitoring equipment is required.
Designed for marine environments, the battery enclosure provides excellent protection against
- Water splash
- Salt air
- Dust
- Outdoor vibration
Suitable for long-term use on boats and yachts.
