battery reassemble problem

You can stand the battery up vertically, then put the bottom plate on. it'll be much easier

 

You do realize the white clamps are bolted to frame of battery. My rebuilder guy doesn't put those screws back in the bottom those 56 or whatever it are those tiny little things those are the ones that will get to penetrating the plastic getting you iso faults . This is especially prevalent on modules that have been through cycles a few times . I've two setups like this now . Been rear ended nothing shifted . I looked very carefully . Before this we dropped a fubar gen2 off a 12 foot fork lift on its roof the HV battery did not move 4 bolts in case to frame and the 4 nylon corners of clamps bolted . The 56 lil screws not in place . We called it good car destroyed

 

Your battery rebuilder has a lack of understanding of the "why" the battery is built as it is. And although there are 4 threaded studs, the white clamps have provision for only two nuts, unless you modify them. Those nuts effectively do nothing for the integrity of the module pack.
Those small fasteners on the bottom are what make the case a structural part of keeping the module pack in alignment.
If you start getting any significant swelling, your pack will buckle upward and rip itself apart. Those small fasteners are what prevent that from happening by making the baseplate...well, ........a baseplate.

It's really just not that hard to do something right. Try it someday.....

 

Very cool when we dropped the thing from 12 ft none of it budged so good for us . Those screws on bottom will get at some point . Screwing into soft plastic Oy.

 

Don't the screws go into threaded metal inserts?
