I need to rearrange my battery storage and as a consequence, one set of a longer pair of the interlinks which are used to join the individual units together.

The ones that come with each unit are about 20cm long terminated with what appear to be Amphenol Surlock connectors which are non-keyed and rotate with positive engagement.

I bought what I thought was a longer set on the web but they transpired to be a 2m long cable with a lug one end with the correct connector the other.

I need something about 1m long with the correct connector on both ends.  I've tried all the local electrical shops with no joy. 

It seems Farnells sell the connectors (if I can work out the exact one) but that then leaves fitting it to the cable - seems to need some sort of substantial crimp.

Any suggestions welcome!

You should have a spare set of short cables with the Amphenol Surlock connector on each end from the Pylontech batteries ?, as you always need one set less than the number of batteries you have. And you have bought a long set with one at the end.

So you cut the short cables in two and connect them to the long one with a 25mm Butt Splice Connector sold for pennies. Cheesy

Either hammer them flat on the cable  Shocked, or treat yourself to a hydraulic crimping tool, you can get them on fleebay or amazon for as little as 20 delivered. fingers crossed!

Yes, I do have a spare and suggested that in the local electrical shops but they were clueless. 

I'll do some research. 

Thanks!

You could just make a lead without hairy butt crimps.
