12.8V 30Ah LiFePO4 Battery Pack for RC Boat / Model Boat Propulsion

A model boat customer needed a power pack that could deliver strong output for propulsion while staying safe and stable on water.
PKNERGY engineered a robust 12.8V 30Ah LiFePO4 pack based on IFR32140 cells, focusing on
low internal resistance, 60A continuous discharge, and long cycle life for repeated use.

Nominal Voltage

12.8V

Capacity

30Ah

Max Continuous Discharge

Customer Profile (Anonymous) & Project Context

The customer builds RC boats that require a strong, stable power source for propulsion and control electronics.
Their key concerns were safety on water, consistent high current output, and long service life under frequent charge/discharge.
Due to confidentiality, the customer name is not disclosed.

Application

RC boat propulsion / power system

Key Requirement

High current + stable output

Priority

Safety on water + long cycle life

Customer environment / device context (optional)

Challenges (What the customer needed to solve)

1) High current demand for propulsion

RC boats draw significant current during acceleration and continuous cruising. The pack must handle sustained load without excessive voltage sag.

2) Outdoor water environment reliability

Water environments raise safety expectations. The customer needed a stable chemistry and predictable operating window for hobby and field use.

3) Long cycle life for repeated use

Frequent charge/discharge cycles require a durable solution. The pack needed strong longevity while maintaining consistent performance.

Engineering note

For propulsion loads, we optimize the pack for low internal resistance and strong current output to reduce voltage sag,
helping the boat maintain speed and responsiveness.

Solution (How PKNERGY engineered the pack)

PKNERGY delivered a LiFePO4 pack designed for RC boat power systems, balancing strong output with safety and long service life.
The pack supports high current operation and repeatable performance for hobby and field environments.

High Output Power

60A continuous discharge supports propulsion load stability during acceleration and cruising.

LiFePO4 Safety

LiFePO4 chemistry offers strong thermal stability, ideal for outdoor hobby products and water-side usage.

Low IR Performance

Internal resistance ≤ 60mΩ helps reduce voltage sag and improves throttle response.

Long Service Life

≥ 2000 cycles (80% DOD) supports long-term use and reduces replacement frequency.

FAQ — Common Questions

Q1: Why choose LiFePO4 for RC boat power?

LiFePO4 offers strong thermal stability and long cycle life, which is ideal for outdoor hobby applications where safety and repeat use matter.

Q2: What data do you need to customize an RC boat battery?

Provide motor/controller voltage, peak/continuous current, target runtime, space limits, connector type, and any waterproofing constraints.
Photos or drawings of the battery bay help confirm fit.

Q3: Can you customize wiring, connectors, and packaging?

Yes. We can customize harness length, connector models, waterproof treatment recommendations, and wrapping/labeling for production.

Q4: How do you reduce voltage sag under load?

We optimize cell selection, pack structure, busbar design, and internal resistance control so the pack can deliver stable current with less drop.
