I purchased the battery monitor for some cheaper lithiums and can't get it to load. AMPED has been awesome answered bunch emails and said I'm sending you a new unit something seems wrong. Installed the new one and wouldn't show up again on my Samsung Android so I had wife bring her iPhone and 2 Samsung tablets to test. It picked right up on her iPhone but neither of the tablets. Has anyone had this issue. I have re downloaded the app and handful of times and even tried the monitors on so acid batteries originally as a test.
