do purpose built battery racks exist?

does something like this exist? would be made of thick steel welded together. would able to carry 4 bricks of SLA stacked in 2's.

Not as far as I have seen. That looks similar to a paper carriers cargo rack though.

Yes, but they're generally propietary, like Currie's Rack Mount Battery System. (Giant uses a similar design on their ebike.)

Been working on this for a few weeks.

I split my Ping and am using romex and 14 ga to marry the two halves.
I'll paint it black tomorrow and it will go on my home made bent.

That is really fine work, SB! Is the box bolted or welded also? Very neet bike too!

i looks pop riveted. be sure to use really thick wire to joint the two halves. not just for efficiency but because the added Vdrop across the joining wire will be assumed by the BMS to be happening inside a cell. if you don't use 4mm thick wire you get BMS cut outs.

nice work tho

Pop rivets and construction adhesive.

4mm? Seems a bit much, tho you can't have too much copper. Four wire romex should suffice to hook up the two halves and another for the charge wires.
14 ga for the bms sensor wires.

Thanks guys. A lot of sweat (and fun) went into my pony.

Baked Sculpty clay over a metal armature and silver leafed.

you need 4mm diameter of copper joining the two halves. you want to keep voltage drop in the wire under 0.05V or it will trip the BMS much earlier than it other wise would. this means you cant use fuses or anderson connectors in that join. big thick terminal block is best. all the other wire can be whatever you want.

Thanks Matt, I guess you should know.
I'll amend my specs.

Well, my purpose build battery rack holds only a couple of Dewalt packs.

Lyen, Those are very interesting tops/battery holders you're using on those batteries. Can you tell me what they are?

Thanks

These are the Dewalt DC509 floodlights. I simply trimmed the inside and mount them onto the seatpost rack. See below:
