A new battery module can be add onto an existing system at any time. Please make sure the new
battery module has an equivalent voltage level (OCV) compare to existing modules. In a serial
connection system, the new module, even has a higher SOH, will follow the system worst SOH
condition module to perform.
5.2.1.1 Make sure the new battery module has an equivalent voltage level (OCV) compare to
existing modules.
5.2.1.2 Shut off the whole battery string's power. Must confirm the D+ and D- terminal are without
