This is a pack of three Castle Creations 6.5mm Polarized Bullet Female Connectors. Polarized connectors have a place in the hearts of many modelers as they make it impossible to destroy their expensive electronics and batteries by plugging them in backwards. However, they have been lacking a connector capable of extremely high currents, constantly having to increase their voltage to maintain amperage levels. But what do you do when you’re maxed out on voltage and your setup requires more amperage than battery connectors on the market will handle? What if you don’t want to or can’t increase your voltage due to size constraints or competition rules? The answer is simple, you go green. The Castle Creations polarized connectors will handle up to 200 amps of continuous current (for the 6.5mm version; 75 amps for the 4.0mm connectors) without breaking a sweat at any voltage level used in R/C applications.
These are the highest rated polarized connector on the market. Not only that, but they’re user friendly too! Castle Creations has added ridges to the housing making them easier to grip, they accept up to massive 6 AWG wire, and they're marked "Battery" and "ESC" for easy reference. Batteries and ESCs aren’t the only things they’re useful for though. Use them on your charger leads, parallel and series harnesses, high current amp/watt meters, and anything else that needs super high current. They’re what "going green" should REALLY mean!

Anyways, I used to love these castle connectors and have installed a number over the years, but my last batch had different tolerances it seems - some were extremely hard to plug/unplug so i had to loosen them up by squeezing the male ends, which made my others far too loose and didn't fit tightly. Due to this problem and needing more of them, i ditched castles and standardized on ec5's which cost a fraction and I have never had an issue with them fitting different, even between the Chinese brands.
pros:
If you need a connector that fits an 8 awg wire then I'd stick with these.
I also like how they are shorter barrels, so they take up less room and can look better.
Walls are thick too - they are made very beefy.
cons:
Expensive
Questionable QC? mfg tolerance
-2 stars because they are very expensive and I had an issue with them not fitting the same, causing me to abandon using them due to cost of replacing
