Low-speed electric vehicles endure a hard, repetitive duty cycle: a sightseeing shuttle on a resort loop, a campus buggy, or a golf fleet car. The pack is charged whenever the vehicle returns, discharged in short bursts, and expected to last a decade on a budget that will not tolerate a premium management board. The JNFN ANT 20ZLV is engineered squarely for that compromise — a 20-series 72 V platform, 300 A continuous output, an IP67 housing that survives washing and rain, and a limp-home mode that lets a driver finish a route instead of abandoning the vehicle on a path.
The board is deliberately conservative in what it asks of the installer. Cell wiring lands on a labelled terminal block, the configuration is a fixed 20-series profile that can be re-flashed for 16 or 24 series, and the CAN frame set matches the motor controller families used in this vehicle class. Everything else is about surviving a depot: reverse polarity tolerance during installation, sealed connectors, and a diagnostic log that a fleet technician can read with a phone.
- 72 V 20-Series 300 A Platform: Sized for the 5 kW to 15 kW motor class typical of shuttles and fleet cars, with headroom for the brief inrush that occurs when a controller is engaged on a slope.
- IP67 Sealed Housing: The board mounts under the seat or in a battery box that gets hosed down during depot cleaning; gasketed connectors and a potted current path mean the enclosure does not care.
- Limp-Home Mode: When a cell group drifts or a temperature threshold is reached, output is progressively limited rather than cut, so the driver can complete the loop and return to the depot under reduced power.
- Vibration-Resistant Termination: Busbar joints and sense connectors are specified against a random vibration profile modelled on the route surfaces these vehicles actually drive — the failure point on cheaper boards.
- Controller-Compatible CAN Frames: The frame set covers the common low-speed vehicle controllers, with a mapping table supplied so an integrator can align identifiers in an afternoon.
- Charge Interlock: A dedicated input prevents traction while the charging connector is engaged — a small function that avoids a very expensive depot accident.
- Optional Driver Display: A 2.4-inch panel can be added to show state of charge, remaining range estimate and fault codes at the dashboard.

Sightseeing shuttles, resort and campus buggies, golf fleet cars and low-speed utility vehicles running 72 V packs are the intended fit. The board also serves small electric sweepers and ground-care vehicles that share the same controller ecosystem.
Fleet operators benefit from the limp-home behaviour and the diagnostic log, while vehicle builders benefit from a single board that can be re-profiled for 60 V and 76 V variants without a hardware change.
Each unit ships with the potted board, a labelled sense harness, four NTC probes, a power lead and a wiring card. Boards are high-pot tested and functionally exercised against a 20-series simulator before packing.
One piece for evaluation, volume pricing from fifty units. Vehicle-specific harness routing, controller identifier mapping and dashboard branding can be configured before shipment. A 24-month limited warranty covers the management board.
