What the BMS Does—and Why It Matters
The Battery Management System (BMS) is the brain of any lithium battery. It monitors, controls, and protects the battery cells through:
- Voltage and current regulation
- Temperature management
- Cell balancing
- Fault detection and shutdown
- Data communication with chargers and controllers
If the BMS fails, the battery fails. That’s why Fleet Lithium developed the NexGen BMS—a smarter, safer, American-engineered system built for real-world performance.
What’s Inside Fleet Lithium’s NexGen BMS
- Active Cell Balancing: Balances cells while charging and discharging. Extends performance and lifespan.
- Internal Heating: Automatically warms cells below 32°F to ensure safe cold-weather charging.
- Integrated Parallel Board: Drop-in capability to add batteries. No harnesses. No dealer intervention.
- Bluetooth App: Monitor real-time amperage, voltage, SOC, temperatures, and error codes from your phone.
- CAN Bus + RS485: Communicates with Navitas, Curtis, and other advanced control systems.
- 700A Max Discharge: High output for acceleration, torque, and extreme use cases.
- Fire Suppression System: Built into the battery case, not the BMS. Activates automatically in thermal events.
Why NexGen Outperforms in Every Application
Golf Carts
- Handles throttle spikes with 700A max discharge
- Real-time diagnostics prevent mid-ride failures
- Plug-and-play expansion for more range
Marine
- Balances uneven loads from accessories
- Cold-weather readiness without add-ons
- CAN Bus integration with marine electronics
RV & Overlanding
- Monitor power usage on the road or off-grid
- Parallel for HVAC and inverter-ready systems
- Works with Victron, Renogy, Redarc, and others
Street-Legal EV & LSV
- High discharge handles acceleration and regen
- Advanced communication with controllers
- Cold start and diagnostics for all-climate driving
Bottom line: Most batteries are built for one purpose. NexGen is built for all of them.
What Customers Actually Need
| Concern | Fleet Lithium Solution |
|---|---|
| Cold charging fails | Internal heating system |
| Uneven cell degradation | Active cell balancing |
| Not enough runtime | Expandable parallel-ready design |
| Battery shutdowns under load | 700A continuous discharge output |
| Lack of diagnostics | Mobile app with live data and fault codes |
| Fire risk concerns | Built-in fire suppression system |
Why Other Brands Don’t Cut It
- EcoBattery: No heating, limited diagnostics, requires external parallel kit
- Allied: Basic passive balancing, limited discharge rate
- RoyPow: Imported electronics, minimal controller integration, poor cold handling
- Bolt Energy: Rebranded hardware, no CAN Bus, no internal safety redundancy
