Nations Alternator Charging System Upgrade for Winnebago Ekko

This upgrade is a perfect option for all Winnebago Ekko owners who have the stock Balmar 170 Amp Alternator with Balmar charge controller, but have upgraded their battery banks to something more powerful than stock.

  • Replaces the factory-installed secondary alternator with a heavy-duty 280XP unit.
  • Integrates seamlessly with the Ekko�s existing 48V or 12V Lithionics battery systems.
  • Provides a massive boost in idle output for faster recovery after overnight camping.
This upgraded alternator is specifically tailored to address the unique power demands of the Winnebago Ekko�s all-season, off-grid design. By installing this high-performance alternator, you benefit from a system that can effectively charge your large battery banks while simultaneously powering the microwave or high-efficiency air conditioning. The alternator charging system utilizes the Wakespeed WS500 regulator to ensure that your lithium batteries receive the precise voltage they need, preventing the common undercharging issues found in stock configurations. As a premier high-amp alternator solution, it allows you to bypass the need for an external generator entirely, even in extreme temperatures. This upgrade ensures that the Ekko�s specialized systems, like the Truma heating and large refrigerator, remain fully operational throughout your journey. Order today.
  • CNC-machined bracketry ensures a perfect, vibration-free fit in the Ford engine bay.
  • Specialized internal cooling fans protect the unit during prolonged high-output cycles.
  • Eliminates energy anxiety by maximizing charging efficiency during short transit drives.

Benefits of the Nations Alternator Upgrade Charging System


  • Higher Amp Alternator & Direct Fit to Factory Location
  • CAN-Based Charge Control
  • Faster charging
  • Configured to read Data from a CAN Network
  • Charging decisions are now made by the BMS, which remembers its state of charge from one engine-start to the next. This means no more overcharging on startups.
  • Battery temperature sensors are eliminated, as the battery temperature becomes just a piece of data sent over the CAN.
  • Current and voltage sensing is improved. They become just other pieces of data - not something that has to be measured remotely.
  • Running other loads will not affect the charge delivered - because the target voltage and current are just data delivered by the batteries.

Thankful for Nations!!
I recently purchased a Nations alternator to upgrade my Winnebago EKKO RV and I am very pleased with the product and the quick delivery of the product. Of note is how easy it was to find the correct system for my camper. It is already bundled together and clearly labeled for EKKO owners!!

Switch from Balmar to Nations
I replaced my Balmar alternator setup on my Winnebago Ekko with the Nations system, and it completely solved the issues I’d been fighting for months. The quality difference is obvious and Nations’ team was also incredibly helpful walking me through the setup. I wish I’d made the switch sooner, hands down the best upgrade I’ve made to my Ekko
