Also this is highly recommended. I used this product for my EV conversion. Mine came in a squeeze tube.

Can be seen here, with full description


No Ox Id A Special- 6oz

or

eBay - 2oz

The idea of using a paste is to smear it lightly on to the terminals, lugs, links, bolts, nuts and washers etc prior to assembly.
Also Motor and controller, shunt and contactor connections.
This way every different metal type is sealed against each other so that no corrosion can take place.

for all forms of battery terminals i have had to protect i have used ether Liquid Electrical Tape or Plasti Dip

both are excellent at stopping oxidation and can be removed cleanly if needed

PS no i havent made a EV yet

Liquid Electrical tape sets very hard. It is difficult to remove and I don't like using it for battery connections because you cannot see the connection and you are not sure it is completely sealed.

It can be used to coat complete circuits to seal them, but try and dig it off.

realy? ok i must have used a totally different stuff than you did (i dont have the tin a mate dose) it set to about 1/2 way between silicone and vinyl flooring. I am using it to coat and protect flight controllers for RC craft of all types and you know the abuse they can take i have even put a few in to ponds/lakes and that have been dry shaken off and sent right back in to service

Sorry to keep on.. but by using a grease rather than a plastic coating allows you to check the torque of your connections at any time, and to make changes/repairs.

I would definitely not recommend using Liquid Electrical Tape plastic coating anywhere around the high voltage/high current connections on an EV conversion.

I've got a bottle of Cabac EJC-300 I'm using for that purpose. Picked it up from my local Gordon MacDonald (they had to order it in for me, $26 or so).

This one bottle will last me forever. It's meant specifically for various combinations aluminium and copper connections. It's a lightweight fumed silica grease and can be used in crimped connections too.

Cabac FAQ

An excellent guide on how to prepare the surfaces for different combinations of metals

Interesting read.
So I see the issue is the copper to aluminium connection.
As on some batteries one terminal is aluminium which becomes the anodic material.
Ie the connection will slowly eat away the battery terminal.

Using Noalox (NO ALuminium OXidisation) or the like slows this issue down.

It also says:
Nuts, flat washers, and lock washers (if used) must be of the same material as the bolt.
Steel bolts may be zinc or cadmium plated or stainless steel.
When steel bolts are used for bolting flat aluminum bus bar or aluminum to copper, the use of Belleville washers in place of flat washers to compensate for the differences in expansion of steel, aluminum, and copper is recommended.
