Does your BMS support overcharge, overdischarge, overcurrent, and temperature protection?

What is a BMS and why do I need it for lithium batteries?

A Battery Management System (BMS) protects lithium battery packs from overcharge, overdischarge, overcurrent, short circuits, and overheating. It ensures longer lifespan, better performance, and user safety.

What is the difference between a hardware BMS and a software BMS?

A hardware BMS offers basic protection functions using fixed circuits. A software BMS includes a microcontroller, allowing advanced functions like SOC/SOH calculation, data logging, communication (CAN/UART), and remote monitoring.

What is active balancing vs passive balancing?

Passive balancing dissipates excess energy as heat, while active balancing redistributes energy between cells, improving efficiency and extending battery life. Active balancing is more suitable for large or high-end battery packs.

Which battery types are compatible with your BMS?

Our BMS products support Li-ion, LiFePO4, LTO, NMC, and custom lithium chemistries. Always confirm voltage and configuration compatibility before use.

How do I choose the right BMS model based on battery voltage and current?

Select a BMS that matches your battery’s series (S) count and max continuous/current ratings. For example, a 13S battery with 30A discharge requires a 13S 30A BMS or higher.

Can I use your BMS for electric bikes, scooters, or golf carts?

Yes. We offer tailored BMS models for e-bikes, e-scooters, electric tricycles, golf carts, and more. Select based on voltage and application needs.

Do you offer customization for different cell counts (e.g. 13S, 16S, 20S)?

Yes, we provide OEM/ODM services. Custom BMS design is available for 3S to 32S or more, depending on your project requirements.

What communication interfaces are supported?

We support UART, RS485, CANBus, SMBus, and Bluetooth. Please check the product model for specific interface availability.

What is the maximum continuous and peak discharge current your BMS supports?

Our BMS ranges from 10A to 500A continuous discharge. Peak current tolerance depends on the MOSFET and design; datasheets specify exact limits.

Does your BMS support overcharge, overdischarge, overcurrent, and temperature protection?

Yes. All models include these protections. Higher-end models feature multi-level safety and redundancy mechanisms.

What’s the balancing current and threshold?

Typical passive balancing current is 30-100mA; active balancing ranges from 0.5A to 5A depending on model. Thresholds are configurable on software BMS models.

What’s the standby current or quiescent current of your BMS?

Standby current varies from <50μA to <200μA for most models, ensuring low battery drain during idle.

How do I wire the BMS to my battery pack? Do you provide connection diagrams?

Yes. Each product includes a wiring diagram in the manual or datasheet. We also offer installation videos and 1-to-1 support.

How do I configure BMS parameters through PC or mobile apps?

We provide PC software (via USB or UART) and mobile apps (Bluetooth) for parameter adjustment, monitoring, and firmware updates.

Can I monitor battery performance in real time?

Yes. With communication-enabled BMS models, real-time monitoring of voltage, current, temperature, SOC, and fault logs is supported.

Do you provide user manuals or configuration software?

All products come with a digital user manual and configuration tools. Download links are available on each product page or via request.

What is the MOQ (Minimum Order Quantity)?

We support low MOQs for most standard models (1-5 pcs). For custom BMS, MOQ depends on complexity and material lead time.

Can I get a sample before bulk order?

Yes. Samples are available for testing and evaluation. Contact us for a quotation and delivery time.

What certifications do your BMS products have?

Our BMS products are CE, RoHS, and FCC certified. Some models can be designed to meet UL or IEC 62133 standards upon request.

What is your typical lead time for production and shipping?

For stock models: 3-7 days. For customized BMS: 10-25 working days depending on R&D and material cycle.
