    I have two Smart UPS 600VA using 12V-7AH battery.

    I want to connect 2 of these Smart UPS to one big 12V-50AH or 12V-100AH battery as follows:


    My questions are:

    1. Can I connect and use these two Smart UPS with one battery? Will these UPSs be damaged?

    2. In case if I can use two Smart UPSs with one battery this way, will these two UPSs be able to charge the big battery?
