The SPC can enlarge the battery life for high frequency use (update period below 5 minutes). 581 581 582 - Seethislinkfor detail: [[https:~~/~~/www.dropbox.com/sh/351dwor6joz8nwh/AADn1BQaAAxLF_QMyU8NkW47a?dl=0>>url:https://www.dropbox.com/sh/351dwor6joz8nwh/AADn1BQaAAxLF_QMyU8NkW47a?dl=0]]506 += 3.
