This was too good to say no to! The Yixiang DIY battery box seems to have all the features we ever wanted from such a case. It has the 200A JK inverter BMS with 4.3" display and communication, a DC breaker, double terminals, side handles, can be equipped with rollers and is stackable with up to 5 boxes!
Also, the inside seems to be well designed and does not leave any further desires: middle frame for strong compression plate, closed backwall to support the cells, front panel and BMS can be removed without unplugging any cables.
Overall, this seems to be THE perfect battery case.
Update:
In regard to the issues with the rollers and broken cardboard box, Yixiang will improve the packaging for customers who order the rollers as well.
Apparently the circuit breaker has a 275A trip current for BOTH breakers in parallel. I cannot verify that and still think the voltage is too low as well.
Yixiang recommends stacking only 2 boxes if the rollers are being used (4 is possible though)
Yixiang will ensure all connections are tightened and checked
