Do you need a BMS for a single Lithium Smart battery?

Fair warning: I'm a pure novice, zero practical experience.

I'll just be having one battery, my needs are modest and the single 12.8V/160Ah should easily cover them.

I think I should be able to use it without a BMS since it has it's own internal BMS.

The data sheet and manual are making me doubt that but that might be because they're written as if you'd never use a single battery. There isn't an installation guide for just using a single battery it's all multi-battery situations where you'd need a BMS to balance the different batteries with one another.

Have I got this right or do you need an external BMS with a single Victron Lithium Smart battery?

These batteries have built in Cell balancing, but do require also there to be an external BMS, to control the chargers and loads:

SuperPacks have all built-in; no thing external required.

Smart Lithiums have something built-in, but still -always- require an external BMS as well.

Cool.

I probably can't wait for them to be available near me (Australia). So I'll have to go with all the bits and bobs instead. Darn.
