UPS. Install a build-out resistor at the COM-OUT port on the last lithium battery. 1. The UPS2000-G-3KRTLL needs to connect to external lithium batteries. Each UPS supports a maximum of eight batteries connected in parallel. This document uses two lithium batteries connected in parallel as an example.
