Four A/C units!

Wow, just wow. . .

Yah, a portable genny wouldn't do it. 8-)

For this thread to not become the monster like the one for those who use LFP for house power, the posts need to stay on topic. Thread drift is so easy to do and I have helped that a few times but.......

Has any one used, or know someone who has used, or heard anything else about, the 123SmartBMS product?

And any thoughts from looking at the site?

The manual and site info leave a few things out, or at least make it a bit hard to understand how to do some things. It is similar to the now defunct House Power BMS but it does not do intermediate high and low voltage warning/cutout, only one voltage for high and one for low.

I know some people using it in an RV installation with 160Ah Winston cells with no reported issues up to now.

Thanks for the info. It would be great if a user has documented their installation and whether it did what they wanted specifically since it seems everyone has different approaches to their installations.
