Took them down. Send me a pm, with an e-mail addy.
 
I'm still building grumble, it's been a stretch but such is life, have made some progress but I'll get there, thanks
 
Gerber files back on-line.

I like your design very much. Simple, modular, well planned out and not a lot of extra not need parts etc.
I would love to access the latestgerberfiles if you are so inclined. I have looked at several designs and think this design is the best
thanks

Learning how to use Gerber files, what version are they, as I can't open them with online gerber viewer? Or what program outputted them?

Not expecting a tutorial, just a point in the right direction, cheers!

They were output with an old version of Altium DXP.

Good Day,

New member here I have browsed thru this thread and I am wondering where you sourced the battery holders for your project.

I currently have a Outback 48 volt 3.5Kw system using AGM cells totaling 28Kw. and 21x250W Pv array. So I am very interested
in this project of yours building a new power wall using 18650 cells.

Thank you in advance for any and all information.
 
Our Chinese brethren are your best bet.
I found the cheapest ebay outfit and fired of an e-mail.
Don't have a link, I'm afraid.

About bloody time... and you're most welcome.
 
Hi

First of all, this looks awesome for my purpose of creating a 7S system, that I can later expand to a 14S system. (Already have the other hardware for 7S).

Can this handle 1500W@7S?

I guess that if I wanted to add a BMS to the system, I would just attach the balance wires between each of the backplanes, correct?

Also let's say that I fill all the backplane slots, then I could just add another set of backplanes in series, right?

Any chance you got the fuse indicators added to the PCB? :)
