Scepterr said:Have you examined the PCB for protection mechanisms? Might be worth keeping on
Would also be kinda awesome to make a PCB to connect all the data lines and have live data for every cell, I think they use i2c protocol
Pogopins in a breadboard would be pretty cheap

Now I have questions.
I uploaded a plastic part to one of the online printing places and about craped when I saw the price, I could get 10 of them machined out of aluminum for the same price.
So to buy or build a 3d printer, what is the cost to run it?
And plastic cost?

Where did you get those LG cells? They aren't cheap.

These is a very nice setup.
I have a couple of questions:
I know your mounts are custom as described earlier, and you answered about the glass fuses...
a) the battery box you are using, can you provide dimensions to it and where you sourced it?
b) What fabrication did you do to it to get your mounts to work specifically?
c) Do you have a pack build video? I'm intrigued at the screws holding down the bus bars - how did you do that, and are you finding any issues?
Thanks a bunch.

The box is about 24"x24" and about 6" deep. I got it from a local electrical surplus place. As far as the fabrication i just had to drill and install new latches because the built in lock stuck in about an inch and hit my last pack because the packs are so large that they stick out about to the door now.
No videos, i just used coarse thread screws with washers to screw right into the plastic cell holders. Seems to hold it well as long as i don't pull on them which will strip them out pretty easily with any force.
As another update, just got a batrium bms andit's up and running as of 10min ago.
Just need to get the shunt installed and figure out how i'm going to setup my remote trip breaker. I'm planning to pull everything off the wall and rearrange to be able to fit both of my battery packs.

Made one design flaw though, the batteries stick out further than i anticipated and interfer with the door on the cabinet closing and locking. I'll have to do some slight fabrication to the door to get it back in working order.

Can you post the stl to the 18650 mounts you used?
