If you run batteries that require 4mm bullet connectors instead of the "normal" plugs these are the ones to use. Unlike the "cage" type banana plugs these will not arch and melt the connections inside your battery. They remain easy to insert and remove wile providing high current capability.
These bullets are very light weight. They feel like plated aluminum, but I could be wrong. They soldered up great though, and the fit is good. Ran them for the first time last weekend and all seems good.
Tried many and these are my favorites. Tension stays perfect even after many many uses. Height is just right to run the wire in vertical or horizontal position. Enough material sticking up so you can get it out with your fingers.
These work great on all my SMC Lipos(shorty) will get more for all my ESCS
Great. Cheap, simple to solder, and the fitment is great,
Reviewers largely praise these 4mm solid gold bullet connectors for easy soldering, good fit and snug connections, with several reporting long-term reliability and no melting in battery connections. Some describe them as lightweight and find them a favourite over alternatives such as Castle and TQ bullets. Criticisms are mixed: one reviewer found they did not fit SMC LiPo packs, another found the connectors awkward to work with, and one reported that the latest batch would not plug into any of their packs. Most reviews are five-star, and the single low rating concerns a recent batch rather than the product in general.
