I finally got around to using these. So far, as one reviewer previously mentioned, they are a poor fit and that's because they are larger than 5 mm. Using calipers, they come out to be about ~ 5.06 mm. They look great, and soldering onto them wasn't a big issue, but unfortunately...a poor fit into the battery bullet hole.

This is a trash product. My connector rings were off by a millimeter, and this caused me to have to my shit up with a torch and even that couldn’t fix it. 1up, stop producing this asap

Absolutely love the security these offer for batteries with direct bullet connectors. They are a tight fit into the connector when new but a dozen or so uses and that does ease up, then the screw holds them super tight. Got one set after seeing them on Yadmah's YT channel a number of times, and now have ordered a few more.

First set was tricky to install but I really want everything to have these after I got the other sets installed correctly. Use a jig, heat up where solder is going, and these end up great. 1up need a video showing how to do these for us rookies.

They are too small. Don't fit snug in 5mm batteries. Don't buy. I had to remove and discard. Waste of money. Bought Meus instead.

What reviewers say

Reviewers report inconsistent fit for these 5mm bullet plugs. Several found the sleeves measured slightly over 5mm (about 5.04 to 5.08mm) and would not insert fully, while one 1/5 reviewer found them too small for 5mm batteries. One owner measured a different set at 4.95mm, which fit well. Reviewers who got a good fit praised the secure, tight connection, easy removal, and colours. One reviewer reported power loss after jumps, which they linked to the sleeves moving freely on the plug. Another noted splotchy, pitted anodizing on the black unit that did not affect performance. Installation was described as tricky for some, with a jig and heat recommended for soldering. One reviewer said the manufacturer was investigating and sent replacement posts.

  • + Secure, tight connection
  • + Easy removal
  • + Good colours
  • + Looks good
  • − Inconsistent bullet diameter and fit
  • − Sleeves move freely, possible power loss
  • − Splotchy anodizing on black unit
  • − Tricky installation and soldering
