Product Description

Smart Battery Management System BMS for E-Bike
Product Overviews
Active Balance

All Smart BMS units are actively balanced, featuring a balance current of 1A and a peak current of 1.2A.

Parallel Protection

Built-in parallel current limiting module eliminates the need for additional parallel modules. Parallel capacity expansion is more convenient and safer.

Built-in Bluetooth

Integrated Bluetooth module allows seamless connectivity without needing an extra BT interface.

App/Program Download

Easily scan the QR code on the BMS to download the mobile app, PC program, and user manuals.

One-Key Setting

Quickly configure parameters with a one-key setting via the mobile app or PC host software.

Comprehensive Protection

Includes basic protections (overcharge, overdischarge, overcurrent, short circuit, temperature) plus four advanced functions: parallel, miswire/drop, and precharge protection.

Rich Interface Support

Features CAN, RS485, UART, DIO, NTC, and KEY ports. Connects to multiple extended accessories (heating, buzzer, touch screen, WiFi, GPS, CAN BOX, switch, etc.) simultaneously. (CAN/RS485 is not default interface)

Support Function Customization: Reserved custom interfaces available for bespoke function requirements.

Applications

The primary objective of a battery management system is to maximize the utilization of residual battery energy. A BMS protects multi-cell battery configurations from deep discharge, over-voltage, extreme fast charge stress, and high discharge currents. It balances individual cells to ensure consistent charging and discharging characteristics across the entire pack.

Crucial for all lithium-ion applications, this BMS is ideal for: electric two-wheelers, electric tricycles, residential energy storage systems, outdoor portable power stations, AGVs, RV power configurations, leased battery swapping networks, electric wheelchairs, lead-acid-to-lithium conversions, electric bicycles, and more.

Frequently Asked Questions
Q1What type of balancing technology is used in this BMS?

The system utilizes third-generation FLYBACK bidirectional DC active balancing technology, providing a highly efficient 1A balancing current (1.2A peak) for superior cell equalization.

Q2Does the protection board support parallel battery configurations?

Yes. It features an integrated 5W parallel current limiter that adjusts automatically based on voltage differentials, ensuring secure parallel operations without requiring extra external modules.

Q3What specialized features set this BMS apart from competitors?

Beyond baseline safety features (overcharge, overdischarge, overcurrent, short circuit, temp protection), it integrates four advanced systems: parallel connection limiting, pre-charge control, drop/miswire detection, and comprehensive hardware safeguards.

Q4What does "BMS with built-in Bluetooth" mean?

It means the Bluetooth communication module is soldered directly onto the PCB board inside the BMS casing. There is no need to plug in a separate external dongle to access wireless features.

Q5Do I need a separate BMS for each specific number of battery strings?

No. We offer multi-string ranges: 4S–8S, 8S–17S, and 8S–24S. For instance, the 4S–8S version adapts automatically to handle anywhere from 4 to 8 series battery configurations.

Q6What is the standard warranty period for this unit?

This active balancing BMS comes with a standard warranty coverage of 12 months.
