Looking for connectors

[Big.mac]

Hi guys, I just had my solar panel fitted to the roof of the van but I’m struggling to source the connectors I need to connect it to my DC-DC.
Cables are 4mm sq, connection point on charger is an M8. I’m looking for the connector style shown in the picture but can’t find a 4-8 anywhere. Anyone able to give me any pointers please? I’ve ordered 50 from AliExpress as they were only £4 but they won’t arrive until June and I’d like to get it working prior to that.

Thanks in advance

Smallest size is for 6mm sq cable. I’m looking for 4mm. I found a couple of places on eBay but they’re all out of stock of the size i want

thats fine . . . the crimp will crush down with no issues.

if your worried just strip and bend the cable back on its self. . . (double up) then just trim down a bit.

then use heatshrink for Tessa tape to make a neat job of it.

Battery cable crimping tool recommendation please

As per the title. Lots of options but the reviews are mixed at best, though anything I buy will not see anything more than light use. Been looking at the hydraulic options, like this ColdShine Hydraulic Crimper Tool Kit Tube Terminals Lugs Battery Cable Wire Crimping Force: Amazon.co.uk...

Any decent electrical wholesaler on your local industrial estate will have them. Yesss, CEF, Edmundsons for example.

Thanks Dell. I usually heat shrink over the end and I have the same crimpers already. Agree they are very good. I’ve got some 6mm connectors so if I can’t get the 4mm ones, I’ll probably do a temp connection using the 6mm and replace them when the slow boat from China delivers the 4mm ones. I’m also not a fan of the yellow insulated connectors someone else suggested in this application. The contact area on the crimp is quite small and I want to get a better connection.

How many amps are you expecting?

How many amps are you expecting?

Probably 8 or 9 on a good day

Then the yellow insulated are more than sufficient.
