The Orion BMS is one of the leading battery management systems on the market today. Known for its durability, flexibility, and American-made quality, it has been trusted for more than a decade by OEMs, Motorsports teams, and DIY builders to safeguard lithium-ion battery packs.

• Significantly smaller enclosure size for 24-72 cell configurations.
• Roughly 40% lower weight on all models due to the new enclosure design and streamlined (removable) heatsink. Minimum heat dissipation requirements apply.
• Considerable boosts in measurement accuracy and processor speed allow for more advanced calculations and logic.
• Direct hardware support for several popular charging protocols including hardware support for both SAE J1772 Type1 and IEC Mennekes Type 2 (directly interfacing with the pilot / proximity lines) and CHAdeMO for DC fast charging. CCS2 is also possible with the addition of the Fellten CCS2 System, contact us for more information.
• Wider input power voltage range (now 12v-24vDC compatible) for better support on heavy vehicles and equipment. The Orion 2 BMS remains fully compatible with 12v applications.
• Ability to directly drive certain contactors on select inputs (bypassing the need for intermediate signal relays in some situations)–see supporting documentation for details.
• Completely redesigned multi-unit series configuration (now using Remote Cell Tap Expansion Modules). This greatly simplifies connecting multiple units together in series and improves the overall reliability.
• New Status LED on the unit to indicate power status and the presence of faults.
• Addition of 2x new Multi-Purpose Output pins with programmable functions.
• Significant algorithm and software enhancements to improve overall system accuracy for parameters such as State of Charge and pack health.

• Capable of measuring up to 24 battery cells connected in series.
• Configurations available in increments of 12 cells in series.
• Centralized design provides high EMI and noise immunity.
• Performs intelligent cell balancing (passive).
• Calculates state of charge (SOC).
• Uses professional automotive-grade locking connectors.
• Calculates discharge current limit (DCL) and charge current limit (CCL).
• Can measure cell voltages between 0.5v and 5.0v.
• Dual (x2) CANBUS 2.0B interfaces which (fully programmable).
• OBD2 diagnostic protocol support.
