Have to agree! I really can't complain cause the price was rite
I opened mine up & there is no chance of a sled or even a bigger battery installed the same way. I plan on just using the parts, I'l wait till I can find 2 LV Grus's on sale & swap the chips over, Plus The Evolv 510's are great to have for spares, not to mention 2 brand new 18650's I realize Evolv just used these as "Testers" & this was good enough for their purpose
@Steamer861 I have an ERM with a battery sled for 18650's in it running the old dna 75 board. Built this a few years ago and it's still going strong. Some crappy, quick, cell phone photos -
I have a few of those also You sent Me the sleds! That also works with the Ebay Hana enclosures
The problem with the New ERM 75c is it's smaller than the older ones. There is absolutely no room for a sled

@Steamer861 Maybe see if the back of a Hana case will fit onto the front of the 75C?
That mite just work! I have 2 old hana's hanging around & it seems the consistency isn't the best
The black one is the same size & will probably work! But the blue one is a few mm short
I have some old similar enclosures from Proto with DNA200's in them & they to are a perfect fit
So now I have the option to use a different back piece & fit an 18650 sled 
Speaking of that reminds me, I need to buy a stun gun to keep the wife at bay. Maybe I can convert my wire welder to something more useful.
That long hair cat of mine is mostly white, I really have to be careful not to wick with it. It is about as fine as rayon.
might do better than rayon 
So I found these Key Stone sleds, I had in my parts collection & they are tinny! I had to use a single strand copper wire to save space! I'v used this kind of wire before & it's good for battery connections I had some magnets here from an other project, I drilled 7/64" holes in the case & the back to accommodate them. I used Crazy Glue to secure them, I also cut the screw heads off the original screws to cover the hole, also crazy glued in I cut a grove in the sled on the + wire side to reese the + wire were it cross's over to the space in board were it fits fine The - wire has plenty of room I also had to file the conners of the sled on the - end.
So now I have an ERM 75c with the original case & an 18650 sled, for swap & go battery changes BTW that the battery that came with, I unsoldered the wires & rewrapped it

Those are the battery sleds I was telling you about. So you already had one. See how they are low profile holders meant to be mounted on a PCB?
