Anyone know the correct name and size for the "prong" type terminals on an Arri 16SB? Best I can come up with so far is "pin end banana jack" which keeps returning the male plugs with the springs and plain sockets when I search for them. I am trying to make up a new cord for my camera and also to make a ground wire for my hi capacity mag (I assume the small socket on my mag is for an external ground). The original coiled cord I got with the camera is still working but the pins are quite dark and I havn't figured out how to get in there and clean them properly. The other end I am going to convert to a more modern plug system to match the new battery pack.

I have a recently acquired Arri 16SB that I am tinkering with that has a battery belt that although it charges to green and is in excellent condition obviously has very little capacity left. Seeing as how I am also into electric vehicles and pretty familiar with battery pack construction I am thinking of rebuilding the belt with new technology cells and converting to 12v at the same time. Googling on this subject and watching a couple YouTube videos where guys are running a couple of R/C car battery packs makes me wonder if this re-powered belt would not just be huge overkill - capacity wise? IE: realistically how much battery capacity do I really need for even the most extreme usage? BTW I already know about converting the magazine to 12v (no problem) and havn't decided whether to try using the Arri variable speed motor I already have (until it gives me trouble) or to by one of the newer Tobin 24v VS motors. I already have a 115v motor for indoor use. Any comments, thoughts or input from some "power users" would be greatly appreciated.

Up for auction is a very nice Arriflex Cooke Speed Panchro 32mm Arri std mount. Ebay listing https://www.ebay.com/itm/312157903445 I also have the same lens in 40mm that I am considering selling. Both lens are in very nice shape.
Recommended watt hour capacity for Arri 16SB battery pack?

Correction to my earlier post: when I said Tobin 24v motor I meant 12v. I cross confused the model # and the voltage, LOL. Probably should have used "AHr capacity" too but used to working with much bigger battery packs.
