Can't really go wrong with the XT90 then. Can handle the current flow for either type and are larger, so they are easier to grab onto to unplug.Yea i should have said i only run 4s mostly only 6s once a month or so when I'm doing something crazy like climbing sandhills.
Took a photo of what I had so you could compare, figured you had at least one of these.
I sometimes get a small spark even plugging in my 2S Lipos on my 4S Rival MT, but it becomes even more evident the larger the battery voltage. Normally this is just an unnerving occurrence like you said, especially the first time it happens. However, very important, any sparking should not happen when hooking up your Lipos to a charger.That is immensely helpful! The connectors are expensive, but I guess you get a lot of bang for the buck.
On a perhaps related note, what size pack does sparking start to become evident? I've been thinking off just starting off with the spark arrest, but perhaps my situation avoids that all together (2-3S). Does Li-Po exhibit any form of off gassing that sparks are a problem for? Or is it just an unnerving occurrence when connecting?
You can buy them in bulk on ebay pretty cheap. They aren't free, but you can get 5 or 10 sets pretty cheaply.
I get sparking a bit when running 2S in series. I don't notice it on my single 2S trucks, but I do notice it a bit on my savage flux and brushless revo. I run 4S in both, two 2S packs in series. Lipo packs are sealed. That's why they puff up when damaged. They generate gas inside I think and puff. From what I understand, they are relatively waterproof as well because of this.
I could see sparking be more of an issue on a gas truck or nitro truck. Not sure why you'd have high voltage lipo packs your plugging/unplugging on one of those, charging I guess.
Be careful with those eBay connectors
I still shop on eBay, I just make sure to buy official Amass connectors.I stopped buying from eBay about 10 years ago...even then it was getting too sketchy for my blood. It has turned into a cheap knockoff marketplace. Sure the stuff is cheap, but who knows what any of it is actually made of.
Yes, that's correct, the XT90 anti-spark connectors do have a resistor built into the plug. It is on the positive end and only on the female (battery) side of the plug. I believe it is a 5.6ohm resistor and this prevents the sparking. Once the XT90 is fully plugged in and full contact is made, it then bypasses this resistor.I didn't realize there were two types of xt90's. The anti-spark and normal. The the AS ones have a diode or resistor/capacitor in them or something to absorb surge?... off to google!
4s may spark on mine as well. I guess I'm not 100% on that. Either I have gotten used to it or maybe I don't notice it happening inside of the nylon cover.
same hereI stopped buying from eBay about 10 years ago...even then it was getting too sketchy for my blood. It has turned into a cheap knockoff marketplace. Sure the stuff is cheap, but who knows what any of it is actually made of.
Yes, but doing so voids the warranty on the esc.I prefer XT90 have them on all my rigs.. just got a v2 infraction...can I cut the stock plugs off like any other esc?..I'm asking bc of the 3rd little wire in the middle
