Nations - 280 AMP Alternator Charging System Upgrade for Winnebago Revel (280A, Wakespeed External Regulator)

Purpose-built for the 2018-present Winnebago Revel (Mercedes-Benz Sprinter 3.0 L) this kit is a direct replacement for the OEM (Winnebago) Balmar 170 Amp unit that’s prone [understatement] to premature failure.

Key Benefits & Features:

• 30–50 % Faster Battery Charging
  Cut idle time and get back on the trail sooner.
• Rock-Solid Reliability
  Fleet-grade components built to thrive in harsh, off-road conditions.
• Massive 280-amp hairpin alternator delivers roughly 3,500 watts of charging power and 180 + amps even at idle, slashing generator or shore-power time
• Clutch-Type Pulley Pre-Installed
  Stops belt slip and protects the front-end accessory drive when pulling big amps
• Wakespeed WS500 advanced external regulator controls charging using battery current, voltage, and temperature for the fastest, safest multi-stage profiles on lithium (LiFePO₄) battery banks
• Smart-system ready — CAN-bus PH-CAN harness talks natively to Lithionics, Victron, and other BMS/monitoring networks; Bluetooth app and USB make firmware updates or fine-tuning easy
• High-efficiency, run-all-day construction: 6-phase 12-diode rectifier, dual internal cooling fans, and heat-shedding ceramic/e-coat finish keep temps low under continuous full-field loads
• Idle-charge optimization lets you top up batteries while parked, maneuvering, or in camp without high engine RPM
• Integrated alternator & battery temperature sensing automatically rolls back output to protect components and extend service life
• Ignition-protected (SAE J1171) and isolated-ground compatible for safe use around fuel systems and modern common-rail diesels
• Supports large battery banks (ideal for 400-600 Ah lithium at 12 V) and pairs perfectly with high-draw inverters, air-conditioning, or induction cooktops
• Complete kit in one box: 280XP alternator, WS500 regulator, PH-CAN van harness, and mounting hardware — backed by a two-year limited warranty and lifetime tech support
• Heavy-Duty Serpentine Belt (Sold Separately)
  Recommended for long-term reliability under higher loads
