Overview
The JBD OH17SA01 is a Smart Battery Management System (Battery Management System / Smart BMS) for LiFePO4 or Li-ion battery packs from 7S to 17S. It supports Bluetooth app monitoring (via an external Bluetooth module), and provides multiple communication interfaces (UART/RS485/CAN) for viewing battery information and adjusting parameters.
Key Features
- Battery chemistry support: LiFePO4 / Li-ion
- Series strings: 7S–17S (supports automatic identification of string number)
- Bluetooth balancing management: supports Bluetooth APP; one-click automatic balance
- Communication interfaces: UART / RS485 / CAN
- Continuous current: 40A–120A
- Maximum peak current: 120A–360A
- Balancing: static equalization; balance current 50–150 mA
- Good heat dissipation: power aluminum substrate; dual aluminum sheet open heat dissipation
- Sampling accuracy: electrostatic voltage sampling accuracy up to 15 mV at standard temperature
- Support display: Yes (RS485 display)
- Imported chip (more stable and efficient)

Details
Use the OH17SA01 smart BMS to monitor and configure 7S–17S LiFePO4 or Li-ion battery packs via UART/RS485/CAN, with Bluetooth app access using the included module.
Select the wiring map that matches your pack series count to connect the balance harness to the BC17/BC0 port correctly.
Main terminals connect to B- and C-, and the balance harness connects to BC17/BC0 according to the series count (up to 17S).
UART/RS485/CAN interfaces allow reading pack data and adjusting key settings during setup and maintenance.
Aluminum heat-spreading construction and accurate voltage sampling support stable operation under load.
Connection ports are clearly labeled for CAN/UART/RS485 communications and NTC temperature sensing.
Suitable for e-bike and light EV battery packs, AGV systems, and home energy storage builds using supported series counts.
The JBD OH17SA01 Smart BMS uses a MOSFET-heavy layout with TVS protection to help manage over-current and overvoltage conditions.
JBD OH17SA01 Smart BMS uses imported chips, TOLL package MOS tubes, and a thermal separation design upgraded to 3.0.
The JBD OH17SA01 smart BMS supports intelligent cell balancing management with multiple balancing modes for battery strings.
Documentation provided includes RoHS, ISO 9001, and SGS certificates along with patent and test report paperwork.
JBD OH17SA01 Smart BMS is commonly used across electric bikes, tricycles, cars, energy storage UPS systems, RVs, and AGV logistics vehicles.
Production equipment covers SMT placement, soldering, and automated testing processes used in manufacturing and quality checks.
