The method listed for buying in the US on their website is to send an email to info@rec-bms-usa.com. I've emailed them twice in the last month, and never heard back. I've checked my spam folder. What are others doing for US deliveries? I see https://offgridsoftwaresolutions.com/ *maybe* but it's expensive. All the sites otherwise listed appear to only serve their local countries. I'm just trying to source the precharge delay relay.
