APPLICATION

ABOUT US

The LTW 13S BMS supports configurations of 7 to 14 battery packs, making it flexible for various power scenarios. With a powerful 30A continuous discharge capability, it ensures your devices receive the power they need while maintaining safety. An integrated charge cut-off function prevents overcharging, while a reverse connection protection mechanism prevents potential damage caused by incorrect wiring.

Safety is paramount, and the LTW 13S BMS features dual safety protection, providing extra protection for your battery system. Multiple hardware protection mechanisms prevent overvoltage, undervoltage, and short circuits, ensuring your battery always operates within safe parameters.

One of the highlights of the LTW 13S BMS is its extremely low quiescent power consumption of only 10μA. This energy-efficient design not only extends the battery system’s lifespan but also minimizes energy waste, making it an environmentally friendly choice.

FAQ

Q: Does this BMS support LiFePO4 or NMC (Lithium-ion) batteries?

A:This BMS is compatible with both LiFePO4and NMC/Lithium-ion batteries. Please specify your battery chemistry when ordering so we can configure it accordingly.
Q: My battery is 14S/15S. Can I use this 13S BMS?

A: No.The BMS must exactly match your battery's series count. Using a BMS with a different series count will result in improper function or potential safety hazards.
Q: What is the difference between "Common Port" and "Separate Port"? Which should I choose?

A: Common Port: Uses a single high-current terminal for both charging and discharging. Benefits: simpler wiring, balanced port wear. Recommended for most users. Separate Port:Has dedicated terminals for charging and discharging. Benefits: independent charging control.
Q: What is the purpose of the "Balancing" function?

A: Balancing is crucial. It acts like a "manager" to keep the voltage of each individual cell in the battery pack equal. This: Maximizes total capacity by preventing the entire pack from being limited by a single cell. Significantly extends battery life by preventing individual cells from deteriorating due to over-charging/discharging.
Q: Does it support Bluetooth APP? What data can I see?

A:Yes, it supports Bluetooth APP connection (via a dedicated module). You can monitor in real-time: Total Voltage, Current, and State of Charge Voltage of Each Individual Cell (most critical data) Temperature, Cycle Count, and Error History
Q: Is it normal for the BMS to get very hot during charging?

A:Slight warmth is normal. However, if it becomes excessively hot (too hot to touch), it is abnormal. Possible causes: Charging current is too high for the BMS rating. Poor heat dissipation (e.g., installed in a confined space). A potential fault in the BMS itself.
Q: Is technical support available?

A: Yes, we provide professional technical support to assist with installation and troubleshooting after your purchase.
Q: What is the Minimum Order Quantity (MOQ)? Can I order samples?

A:We accept sample orders for testing and validation. Please contact our sales team for specific MOQ and sample policies.
