Capacity Test Wiring Diagram

Hey all,

I finished my top balance, and wired my battery bank into the 24v setup to do a capacity test. I'm currently wiring a few components together to test a few of the components, and do a capacity test. I'd love to get some feedback to make sure the configuration looks OK for a few quick tests - not planning on leaving it like this permanently.

Additionally, the Multiplus acts as a charger, so I'd like to use it to charge the battery bank back up once I've done the capacity test, rather than rely on my 10A bench charger. I'm assuming that can be done by wiring an extension cord to the AC Input terminals within the Multiplus, but any additional insight into that process would be helpful as well.

Pic attached, but the highlights of the setup are:

8 x 280A LiFePo4 battery cells, wired in 8s for 24V
200A Daly Smart BMS
QWORK Battery Monitor: https://www.amazon.com/gp/product/B0824X5MKM/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1
Class T Fuse, 200A: https://www.amazon.com/gp/product/B001539B60/ref=ppx_yo_dt_b_asin_title_o02_s02?ie=UTF8&psc=1
Victron MultiPlus 300VA 24V Inverter Charger w/ 70 Amp charge: https://www.amazon.com/gp/product/B0054PRVAS/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1
GFCI Outlet, 20A: https://www.amazon.com/gp/product/B08N5HJ337/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1

I'm using 10 AWG wire for the AC Out to the Outlet
1/0 wire between the battery, t-fuse, and inverter on the + side
1/0 between the inverter and the battery monitor on the - side
The BMS came with seemingly smaller cables attached, but I'm assuming they'll be fine to use between the battery (-) terminal and the battery monitor

Thanks for your help!

Need a feed for the battery monitor, a connection from battery positive to b+ on the shunt, although not shown an any instalation diagram, a small In line fuse, would be a safety feature.
