Orion JR2 BMS — 48 V Class (1–16S)

Compact, affordable battery management for 48 V nominal systems (up to 60 V max). JR2 brings core Orion 02 safety—OV/UV/OT/UT, OCP, passive balance—into a smaller package.

1–16 cells in series
Passive balancing
Optional CAN 2.0B
OBD-II support

Orion JR2 Battery Management System Controller

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 large HV controllers. It monitors cell voltages and temperatures, computes SOC, enforces CCL/DCL, and communicates with chargers/VCUs via optional CAN 2.0B.

Where JR2 excels

48 V ESS & Backup

Home/storage cabinets, telecom UPS, and micro-grid nodes with strict safety requirements.

Light EV / Robotics

AGVs, AMRs, e-moto, powersports—when size, cost, and reliable protection matter.

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 required?

No—CAN 2.0B is optional but recommended 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?

Select the Hall-effect model that matches your pack’s peak/continuous current (e.g., CS118200, CS124500B, CS133800B, CS1371KB).
