Amass 10 Pair XT90 Male Female Bullet Connectors Power Plugs for RC Lipo Battery Motor … …

These connectors are pretty good quality. Great fitting connectors with good current flow. 👍

I've been an EC-3 guy for a while, but these connectors are making me transition to XT-60 and 90. The Amass product is excellent: The fit is perfect, the connections to solder are easy to access, and the supplied click on covers fit perfectly and can be removed if you have to resolder. Great value as well. Tip: if you're creating a voltage monitoring lead and adding a small voltage lead to the connection, followed by heat shrink, use a small reamer or round file to enlarge the cover holes. I've created perfect harnesses this way. Thank you Amass.

Works great,no more melted plugs.

These connectors are better suited for high current and voltage than something like a deans connector, and they have the added benefit of being safer to keep around electronics and metal. Since the male and female sides are both inside their own housings, it is much less likely to short out a battery. And depending on your battery type, this could save you from blowing a battery circuit or even burning the battery on fire. With LiPo batteries these days, you never really know, and because they are so powerful, I would recommend changing all your connections to these XT90s... It makes everything easier to work with and safer. (Please learn how to solder the proper connections before attempting any of this... there are certain ways to change the connectors safely without creating a short)I am also using these for my Lithium Ion (21700) solar power bank, and Lithium Ion (18650) CPAP Machine USP Backup.The high amperage means that at 48VDC &90Amps, I can run my solar system up to a 25 Amp Breaker on 125VAC Inverter even if it has a low efficiency ( like 75%)... This makes it very simple and safe to plug and play anything battery or otherwise in my home or during travel with CPAP machine. For Higher DC voltage solar setups, you can get even more from these little connectors, and probably run 3 or 4 15Amp breakers on a Single connection.

Connectors are very good quality, all connectors mate firmly with each other and also with 3rd party XT-90s, however they do not include enough heatshrink. The 40 8mm long connections on the back of the battery would require a minimum of 400mm of heatshrink tube to cover. However, only 200mm (100 black and 100 red) are included in the kit, meaning if you are 100% efficient and don't have any mishaps/mismeasurements, you can only cover half of the terminals.

They are durable, easy to connect and disconnect

I converted my 2 competition truggy 4s packs, 4s bash pack, and 3 x 3s bash packs tonight. I really like these xt90's, they don't heat up on 4 and 6s bash sessions. I have not taken my truggy to track yet but I think they will hold up just fine since that will run less power than my Notorious 6s basher. Soldering these connects is very simple. I set my soldering station to 800c, tin the tip, touch the leads on the backside of the xt90 and feed solder in immediately, they take on solder and stick amazingly well. I will convert all my 3s+ packs and run this for anything 1/8th scale.

Works great love how there labled positive negative

Funciona como se espera. 👍

These are great connectors. They solder easily and mate securely. I’m not certain what my average current flowing through them is but the old SAE two pin connectors got quite hot to the touch. These connectors don’t heat up at all under the same conditions. I like the size because I feel that they are better for unplugging because you can get a secure grip on them. The backing they come with is great too. Covers the terminals and click nicely in place.

Nice product with high quality. The delivery was also surprisingly fast given I'm in Australia. Thank you.

While with any of these type of connectors they are a bit difficult to solder but the recess for the wire helps. It JUST fits 10 AWG and don't forget to put pieces of heat shrink and the backing on BEFORE soldering. The connectors start off a very fit and after a few connects and disconnects are still nice and snug but reasonable to put together and take apart.The connectors fit nice and snug, I can't comment on their amperage handling capacity yet but they should handle the 7.5-ish amps at 12v for which I am using them for.Overall I'm happy with my purchase.

seems to be of decent quality
