If you use this battery in any van that has a DC-DC converter to charge house batteries from the chassis battery and that DC-DC converter determines whether the engine is running or not using voltage. Lithium batteries have a much higher resting voltage than lead-based batteries and will maintain high voltage for much of their useful capacity. This can result in DC-DC converters that stay active charging house batteries for long after you have shut the engine off. Owl takes no responsibility for any issues that are caused by this high resting voltage property of lithium batteries and it is up to the customer to ensure that their van will not have issues with high resting voltage. Please check with your builder/fitter if you have any questions. The full resting voltage of this battery is approximately 13.3V and it will stay above 13V until it is at approximately 30%. If you are using this battery, it can cause the DC-DC converter to stay on.
