I want to use the 2000w PowerStation outside my RV. It’s ideal during “quiet hours” when generators are prohibited. However the RV connections are outside. The unit can be easily chained securely. But the batteries themselves could be stolen from the PowerStation. I’d like to see an accessory or bracket that locks all 4 batteries to the PowerStation for security and to prevent theft. This is a problem anytime you need unattended operation of the PowerStation.
