BetterBMS spent five years inside EVDrive's own performance packs before it ever shipped. Cell-level supervision, real fault tolerance, and configurability sized for large packs, not retrofit onto an engine controller.
Hardened across five years of real performance deployments, including a top-speed-record Corvette pack, before it was ever sold.
Monitors and balances at the individual cell, surfacing a weak or drifting cell before it drags a whole string.
CAN integration, field-updatable firmware, and direct support from the team that wrote it, not a reseller queue.
Budgetary ranges shown to help you scope. Final pricing confirmed with your pack configuration.
Tell us your chemistry, series-and-parallel layout, current limits, and thermal thresholds. We spec the master, satellites, and harness for your exact pack, the same way we build our own. No fixed topology, no closed ecosystem.
Where sport-tuned controllers add battery features onto an EMS, cell supervision is the entire job here.
