Winnebago Ekko Additional & Replacement Battery Installations

Add a new lithium battery to your Winnebago Ekko or replace an existing Ekko battery that is losing capacity.

When an Additional Ekko Battery Makes Sense

Some owners add a second battery to increase the capacity of the Ekko power system. This is common for Ekkos used in off-grid locations, winter conditions, or trips with limited solar exposure. An additional battery benefits owners who:

• Camp off-grid in their Winnebago Ekko for multiple days
• Rely heavily on the inverter for cooking or electronics
• Travel where sunlight is limited for solar charging
• Use the Ekko as a basecamp with high electrical demand
• Want more usable energy for heat, fans, water systems, or Starlink

An expanded Ekko lithium battery bank increases stored energy and extends off-grid runtime.

When a Replacement Ekko Battery Is Needed

Many Winnebago Ekko vans are now reaching the age where the original house batteries begin to decline. Most factory Ekko lithium batteries show reduced performance after several years of cycling. Common signs include:

• Shorter runtime for the Ekko electrical system
• Slow charging from alternator or solar
• Inverter tripping under moderate loads
• Drops in capacity during cold weather
• Inconsistent performance during off-grid camping

A replacement Ekko battery restores dependable power for heating, cooking, refrigeration, lighting, and 12V accessories.
