Summary of Major Improvements
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 SAE J1772 (directly interfacing with the pilot / proximity lines) and CHAdeMO for DC fast charging.
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.

Q :
Hello. I am keen to purchase an Orion 2 BMS for delivery to my mother in France, who will bring it to me in South Africa on 6th February. I am unsure about my chemistry yet, so my exact cell count is still unclear. It will either be 108 or 96. If I buy the 108 Orion kit, can it be reconfigured by me to use only 96 cells?
A: Hello, Orion 2 BMS 108 cells will work with 96 cells or less. Thanks!
