Simple way to extend Daly 16s BMS voltage sensing wiring harness?

[apctjb]

Switching to Daly BMS but the length stock wiring harness that comes with the BMS is to short for my battery bank. I have three 16S batteries, each with there own BMS so hoping there is a simpler way to extend the wiring harness other than soldering 51 extension wires (3 x 17 each harness). The Daly uses a straight 17 pin flat cable connector and so far have not found anything to match.

I emailed Daly to see if they sell a longer harness, but got no response...

Use DIN rail terminal blocks.

I’ve made them just long enough and extended them. It all works great. This 18 gauge silicone stuff from Amazon is a dream to work with. Doesn’t tangle easily. Twisted ends together soldered and used heavy walled adhesive lined heat shrink. ……
