Brand new 12/100Ah lithium battery smart. Zero volts. No bluetooth.

Is it normal to receive a new battery in shutdown state? 1 volt and no bluetooth? Is this normal to receive them like this??

I understood the batteries were half charged to keep them in optimum condition. I have a small Victron battery charger 12/7A. I am reluctant to try and charge it at this slow rate. I am hoping to keep this battery going for a long time with all the relevant Victron protection devices. I have designed the system so can add another similar battery when I can afford one in series. Not cheap!

Should I wait until I can charge with my Multiplus Inv/charger which is halfway through installation and not wired up???

Or get a replacement battery.....

@Philotechnic If your brand new battery has arrived with such a low terminal voltage that the bluetooth does not work, it is broken.

Contact your supplier and ask for a replacement.

What is the build date? (first 4 numbers of the serial #)

Looks like its knackered!

@Philotechnic What should I be getting from a brand new one?

Your battery is damaged beyond reliable use.

Could be that the battery has reduced Ah capacity. Could be that a cell has higher than speced self discharge.

LSB manual.

Contact your supplier.
