for the appliance now without upgrade ok pa yang battery mo , but if meron ng additional load like induction cooker mag bottle neck na battery mo. magagamit mo naman yan induction cooker with one battery but there is a tendency mag trip yung BMS mo due to continues discharge limit. yung can do slective loading during mag luluto ka and dapat sa umaga lang kung naka full load ka. for peace of mind add a second battery. thanks
