I strongly urge you to reconsider that one in favour of a B2A24S15P (150a) OR B2A24S20P (200a) which CAN do LFP 8S. Several people here have had "issues" with the B2A8S models. I found one of the Best Listing with the data, downloads etc is from Hankzor (Vendor)

TIPS: (See photo below)
- The BMS P- & B- silicone wires for the "15P model" are 7-AWG and both do fit into a 4-AWG Butt Connector.
- You can use 4-AWG Silicone wire to the Terminal Lugs to attach to cell + Batt Post.
- Hydraulic Crimper is Very Highly Recommended. (I use a YQK-8 Ton - works fine but tad fiddly, use a little cardboard to steady the dies straight.
- 1/2" Shrink Wrap for teh wires is perfect BTW, get lots.
-*- The BUTT connector is tough, The one linked here provides a mid-point deadstop (important), have a dimpled interior for added grab and provides 13MM of internal space on each side (enough for double crimp). Be VERY Careful on Butt Connector Specs they are NOT all the same !

NB: PITA to handle one person. Use a VICE to hold the unit, "not too hard eh", then it is MUCH easier to put the cable with "lug or" into the slot and hold it till you start to actually crimp the wires. Also NOTE, AWG is "slightly" bigger than the Metric but it is fine but leaves tiny "wings" once fully crimped, you will NEVER get the dies tight together because of that, it IS ok.

The BMS Extensions: I made mine this long because of how I built my battery boxes.
BTW, I ended up with RED jacketed as they were out of stock on Blue. like the other wires, ultra-fine stranded wire in thick silicone jacket.
