https://www.trailmanorowners.com/for...25&postcount=3 I separate that battery to live in its own Thread (here).
Although it might be OK to simply tape the cells together with the BMS, and then set the assembly into a small open-faced wooden box, I intend to do a couple of changes.
These are Eve "type "N" cells. Eve says that they will last for up to 6000 cycles with moderate depth of discharge, a much longer lifespan than they advertised for cells of the previous "K" version. But they might last even longer as a compressed pack. I already bought compression screws, and I intend to compress the pack up to about 640 lbs of pressure between two steel "compression plates" after my compression plates arrive from Amazon, and I cut them down to size 8" tall by about 9" wide. (4 compression screws, each tightened to about 160 lbs).
The el-cheapo "Daly Smart BMS" unit BMS unit provides equal length ""battery -" and "common -" jumpers with 8mm binding lugs. But the welded battery terminal assembly provide for 6mm studs, and the top-side contact area on those welded terminals is quite small. I'll be cutting the BMS -> battery binding lug, and replacing it with 6mm terminal lug. The BMS jumpers are also AWG-2, much smaller than 2/0 wiring I will be using elsewhere. (from the "+12v" battery terminal" and from my battery bus bolts into the Inverter.) Reducing their length is a good thing, they will add a lot of resistance when the Inverter runs hard.
I can (and have) tightened the stud bolts to almost 70 inch-lbs on these "welded terminals", they're rated for more than 80. (That's 3x more torque than you use with old-style into-the-pack terminal threaded stud holes.) High pressure between the lug and the terminal assembly helps to make up for the small terminal area.
Yum! Charging up a new 230Ah LFP battery pack.
