Hi all

Please could someone direct me to where I can buy some power cables suitable for seplos system? Picture attached.

Thanks

If you bought these used, they are supposed to come with the kit...
Contact the seller?
If you got them straight from Seplos they would have been included.
 
they are using futronics connectors.
i ordered my new ones at aliexpress minerals store, as i found seplos overcharges for their cables and they are a maximum length of 2 meters

Odd that seemingly no one has figured this out. The connectors supplied can't accommodate a wire gauge large enough for a 15 kWh battery box.

I mean they are fine if you don't need to draw 200A from it.

Also you can get better wire - like arcticflex blue - 1AWG will carry 200A and work with the standard connectors.

50 mm2 is fine for short burst of 245 a, or 150a continues...
If you're pulling 150a ( or more than .5c from 280a cells continues) you need more batteries, not thicker cables
 
My Seplos style quick connectors arrived today via Aliexpress. They actually came five days earlier than anticipated. I swapped my cabling from 2/0 to 1/0, which seems to fit perfectly. I also confirmed they match the connectors on my Apexium box. I have 45 kWh, so I won't be pulling more than 100 amps from each box. You can see the copper sticking out from beneath the terminal.
