Same 314Ah Capacity — So Should You Choose the T300 or T300L?
Same 314Ah Capacity — T300 vs T300L
In energy storage, backup power, and RV applications, users today aren’t just looking for big capacity anymore. Fitment, available space, and system compatibility matter just as much.
That’s why Tistar developed the T300 and T300L 12.8V 314Ah LiFePO₄ batteries. While both models share the same capacity and core performance, they differ in physical design — giving you more flexibility depending on your installation space.
⚡ Same Capacity, Same High Performance
Both the T300 and T300L use a 12.8V 314Ah LiFePO₄ configuration, delivering a total energy capacity of 4019.2Wh. In terms of storage capability, they are identical — designed to provide reliable power for home energy storage, caravans, off-grid systems, and backup power setups.
🔧 Key Features (Both Models)
| IEC Certification | IEC 62619 certified battery pack |
| Cycle Life | Over 6000 cycles |
| Battery Management | Built-in smart BMS (Battery Management System) |
| Design | Lightweight, compact, maintenance-free |
| Temperature | Stable across wide temperature range |
| Chemistry | Safer LiFePO₄ chemistry |
⚡ Output Performance (Both Models)
| Charge Cut-off Voltage | 14.6V |
| Discharge Cut-off Voltage | 10V |
| Max Discharge Current | 350A (3s) |
| Continuous Discharge Current | 260A |
Whether you’re running an inverter, an energy storage system, or high-power appliances, both the T300 and T300L deliver stable and consistent power.
📊 T300 vs T300L Comparison
| Item | T300 | T300L |
|---|---|---|
| Capacity | 314Ah / 4019.2Wh | 314Ah / 4019.2Wh |
| Design | Compact | Low-profile wide |
| Dimensions | 387 × 207 × 273 mm | 522 × 241 × 218 mm |
| Weight | 26 kg | 27.8 kg |
| Best Fit | Tight spaces / shorter length | Low height / wide compartments |
📐 Different Sizes for Different Installations
The T300 features a compact structure, making it ideal for installations where space length is limited, such as under-seat RV compartments or small battery boxes.
The T300L uses a longer and lower-profile design, better suited for wider installations such as boat battery bays, underfloor caravan systems, or height-restricted compartments.
🔗 Expandable with Parallel Connection
Both the T300 and T300L support up to 4 units in parallel, allowing you to scale your energy storage system as needed. If you need longer runtime or larger capacity, you can simply expand your system without changing your existing setup.
🌍 Built for a Wide Range of Applications
With high capacity, long cycle life, and stable discharge performance, both models are suitable for:
- Caravan power systems
- Marine and boating applications
- Off-grid solar storage
- Home backup power
- 4WD touring setups
- Commercial energy storage systems
Choose based on your installation space, layout, and system design.
🧭 How to Choose
If you’re working with tighter or more compact spaces and need a smaller footprint in length, the T300 is the better fit.
If your setup requires a lower height profile or a wider layout — especially in underfloor or larger battery bays — the T300L offers a clear advantage.
In all other aspects — capacity, lifespan, output, and safety — they’re identical. It really comes down to one thing: fitment flexibility.
🔋Final Thoughts: Same Power, Smarter Fit
The T300 and T300L give users more freedom in system design without compromising performance. With identical 314Ah capacity, high output power, and long cycle life, the only difference is how they fit into your space.
Whether you’re building out a caravan, a marine system, or an off-grid energy setup, you can choose the model that suits your layout best — and enjoy efficient, reliable energy wherever you go.
