How to build a LiFePo4 battery bank.
A lot of people dont have any idea how easy it is to build a DIY LiFePo4 12V battery so I'll post a deicent video of how to do it so people can decide for themselves if it is in there capability. ...

Overkill BMS's seem to have a very good rep; however, to my knowledge they don't make BMS's larger than 120a. For those who have 2000-3000w inverters with 200-300a current requirements what options do they have? Daly makes a few 150-250a models, but they have a somewhat sketchy rep. I suppose one could parallel multiple Overkill 100-120a BMS's and LifePo4 battery packs.
Running several in parallel is not a bad idea, it would be the same as running several drop in batteries in parallel. It spreads the load (and heat) across multiple devices, and provides redundancy as well. On the down side, you would need to look at several screens on the app to see what each pack is doing, but that is not a huge deal. If you are handy you could also merge the data from each BMS into one stream as the protocol is open source.
To give credit where credit is due - these are not Overkill Solar's BMS, they are just retailing/rebranding LLT powers BMS.
