Expandability of battery banks

[addieboy]

Hello everyone. Planning to build a 16s/280ah battery bank using a daly smart bms 300a. Question is, can I add another set or sets in the future in parallel to get twice or thrice the capacity? I cant seem to find information if the multiple bms's can be paralleled.

E.g.,
Set 1 - Daly 16s Smart 300A connected to 16pcs EVE 280ah
Set 2 - Daly 16s Smart 300A connected to 16pcs EVE 280ah
Set 3 - Daly 16s Smart 300A connected to 16pcs EVE 280ah
...and so on

Figured this should be covered in a video. I have tried various wiring configurations over the years, and using busbar w/ equal length conductor has never given me problems. I would still have issues with other common wiring methods. Would love to hear what you guys recommend. Keep in mind that...

Thanks for this. I was wondering, why the busbar? How about just use the same length of wire and terminated to the breaker?

If the breaker terminal can holds three or four lugs, go for it.

1 breaker 1 conductor only, per code and best practice.

Square-D QO breakers are rated for 2 conductors

touché...wouldn't exactly call it best practice though.

how about this one? this is rail mountable

Hey that looks nice! A compact busbar (power block) with the right number of lugs! Is it pricey?

Edit. I found it for $34
