Did the price change on that? I'm seeing $200 when I thought the pre-built ones used to be $280, hence why that 2nd option I was considering was building it myself using those cells. $200 isn't bad if it includes a case and some basic balancing boards. -4*F minimum charging temperature is tempting too compared to the typical 32*F threshold. 40A max continuous discharge shouldn't be an issue since the meanwell doesn't charge much higher than that and has had no issues so staying below 40A shouldn't be a problem at all.

Did you replace the connectors on that battery? They look pretty flimsy.

EDIT: Ah, I see now that the tabs can be removed.
