Orion JR2 BMS — 48 V Class (1–16S)

Compact, affordable battery management for 48 V nominal systems (up to 60 V max). The JR2 brings core Orion protections—OV/UV/OT/UT, OCP—and passive balancing into a smaller package, with CAN-enabled integration for chargers, gateways, and vehicle controllers.

  • 1–16 cells in series
  • 48 V class (60 V max)
  • CAN 2.0B (included)
  • OBD-II diagnostics
Series range 1–16S
Voltage class 48 V nominal (60 V max)

Why Orion JR2

Built for 48 V energy storage, e-mobility, robotics, and backup power, the JR2 delivers Orion-grade cell supervision and protection without the cost or complexity of high-voltage controllers. It monitors cell voltages and temperatures, computes SOC, enforces CCL/DCL, and communicates over CAN 2.0B for clean integration with chargers and control systems.

Configuration guidance

Choose your current sensor range

Select the smallest sensor that safely covers your peak current (not just continuous) to keep accuracy high while avoiding clipped transients.

  • 200A — light EV, robotics, small ESS
  • 500A — general purpose (common choice)
  • 750A — high-burst traction / larger ESS
  • 1000A — heavy traction / industrial

Setup vs diagnostics (PC interfaces)

JR2 supports both direct programming and CAN-based diagnostics:

  • RS232 → USB adapter: direct configuration/programming.
  • CANdapter: CAN logging, live telemetry, diagnostics.

If you’re commissioning a new harness for the first time, a Cell Tap Validator can prevent first power-on mistakes.

FAQs

How many cells can JR2 manage?

From 1 to 16 cells in series. For higher series counts, see the Orion 02 family.

Is CAN included on this kit?

Yes—this is the JR2 w/CAN kit. CAN 2.0B is included for charger/VCU integration and telemetry.

Does JR2 balance cells?

Yes. JR2 uses passive balancing to maintain cell alignment and pack health.

What current sensor should I pick?

Pick the smallest sensor that safely covers your peak current. The kit includes a Hall-effect sensor selected by your range option (OEM part numbers include CS118200, CS124500B, CS133800B, CS1371KB).

Which harness SKUs are included?

Main I/O: CWHJRMC2. Cell tap: CWHJ2166 (also referenced as CWHJR166 in some listings). Current sensor harness: CWHJ2CUR.

Do I need RS232 → USB or CANdapter?

RS232 → USB is used for direct programming/configuration; CANdapter is used for CAN diagnostics, logging, and live telemetry. Many builds use both (setup + commissioning).
