Testing the LiThink 334Ah LiFePO4 Battery (And a Huge Mistake...)

In this video, we are putting the massive LiThink 12.8V 334Ah LiFePO4 battery through its paces. During the review, things took an unexpected turn when I accidentally short-circuited the wiring directly to the pure sine wave inverters!

HIGH-PERFORMANCE PROTECTION

300A Smart BMS.

More power for RV loads.

The 300A Smart BMS delivers high continuous power and monitors each cell in real time. It protects against overcharging, discharging, overcurrent, short circuits, and extreme temperatures – giving your 12V RV, marine, and off-grid system greater power reserves with reliable control.

Cold-resistant and ready to go

The intelligent BMS automatically pauses charging at 32°F / 0°C and resumes it at 41°F / 5°C. Discharge protection works down to -4°F / -20°C and protects the battery during winter use in motorhomes, vans, and boats.

Frequently Asked Questions

Do you still have questions?
You can find more information in our frequently asked questions.

F: What applications is the LiThink 12V 334Ah MINI best suited for?

A: It is a powerful solution for 12V power supply systems in motorhomes and vans, especially for under-seat or seat box installations, as well as for off-grid solar systems, marine and fishing applications, and high-performance inverter systems that require large capacity with stable discharge performance.

F: What does ECE R10 mean in practical use?

A: ECE R10 refers to vehicle EMC compliance. In practice, this means the battery is designed for motorhome and van power supply environments in which inverters, DC-DC chargers, and other onboard devices must work together reliably.

F: How powerful is the BMS, and what does that mean for high-load applications?

A: The battery uses a 300A BMS board with 300A continuous charging and discharging current. It also supports staggered peak power of 1000A/1 s, 900A/3 s, 600A/5 s, and 450A/10 s, which is useful for startup currents such as those in compressors and pumps. The correct inverter size always depends on your wiring, protective devices, and the overall system design.

Q: Can I expand the battery in series or in parallel?

A: Yes. The system supports configurations up to 4P4S (up to 4 in parallel and 4 in series). For the most stable configuration, use matching batteries of the same model and condition, and bring them to a similar state of charge or voltage before connecting them.
