Seabee Posted July 3, 2023 Share Posted July 3, 2023 I used to use 4mm connectors as then that was all that appeared to be available but found some inconsistency in the fit when mixing them, then came Deans which were in my opinion just awful. Now I only use XT60s but it is worth noting that often it is the plastic that is making the tight connection not the connectors themselves. In some cases the split pins after a lot of use have compressed and don't make a really good contact but they are easily uncompressed with a nail or similar. It is worth visually checking the split pins in the XT60 plug on the ESC before plugging it into the LiPO. 2 Quote Link to comment Share on other sites More sharing options...
leccyflyer Posted July 4, 2023 Author Share Posted July 4, 2023 That point about the plastic housing giving the false impression that you are getting a good solid connection does seem to be an issue, at least for the EC5s. Personally I'm much happier now having replaced those, but those 6mm gold bullets do seem awfy short! Quote Link to comment Share on other sites More sharing options...

My 6mm bullets are indeed shorter than the 4mm ones, and I have used them a lot in higher current applications. Photo attached of 4mm and 6mm bullets both separated and together, plus a ruler confirming sizes/ Dick Thanks for the pics of the 6mm bullets - look worth investigating. Re the 3" - OK - I guessed, but I wasn't far off: Quote Link to comment Share on other sites More sharing options...
Dickw Posted July 4, 2023 Share Posted July 4, 2023 Yes Mike, looks like your 4mm bullet connectors are quite a bit longer than mine. I can make mine even more compact if I am careful with the way the wires are solder in Dick Quote Link to comment Share on other sites More sharing options...

SM Modelbau in Germany fit them to their 400amp current sensor, and I regularly see peak currents of approaching 200 amps on mine. many years ago when F5B was limited to 6s Lipo and I was using only 5s I did see current peaks of approaching 400A. (and even slightly over when I had an ESC fire 😀) Dick 1 Quote Link to comment Share on other sites More sharing options...
