Don't laugh guys. I have a physical problemo flying my electrics. I call it TICS Thumb Is Cracking Syndrome, and I'm sick of it. Here's the deal - when I have several days in a row where I'm using the LIPO batteries a LOT, plugging/unplugging them from the chargers and the helis like 40 times, I end up with the tips on my fingers (thumb and 1st finger) hurting, chewed up, and even splitting where it hurts to grab anything with my thumb. Some of my EC5 connectors are not as tight as others, but none of them are "easy" to plug/pull apart. Needless to say, this causes me grief because I am (of course) using the SAME thumb to FLY WITH pinching the stick!

Any advice on how the pull these stupid plugs apart without injuring myself would be appreciated. Maybe a thin glove? Thank you.

I would think that you could slide something long and thin between the plugs and give you a little more leverage.

Some guys use snap ring pliers (expand when the handles are closed together) to push the connectors away from each other. It works surprisingly well, although it does chew up the plastic a little bit.

I have seen this if you use different brand EC-5s. Use a tool like two sets of needle nose pliers of pver the connectors and use the tips as leverage to get them apart...

I suggest you hire someone to charge and plug/unplug your batteries. Obviously a sign you are flying too much.

You could do away with the plastic sheath and just have 5mm bullet connections, just heat shrink over the females.

60% of the time, it works every time!

Might Help!!

I have the same problem, but it is more of a dry skin condition that causes my thumbs to split....

I use a lotion called Corn Huskers, both morning and night before bed... this seems to keep things working for me, and limits any cracking/splitting...

Might help you out??

Good Luck, Stan

Richard and Stan hit the nail on the head..

I was of the school of thought, to cut the EC5 housings apart to have just a single bullet to separate.
Danny Melnik said he just uses bullets and heat shrinks them.
Way better solution in my opinion. Much eaiser to make a series connection. And a lot less wiring too. The corn huskers lotion work great for keeping your thumbs from cracking..

P.S. Put a Jeti Anti spark connection in there as well. To keep from pitting the contacts.

Sticky connectors

Just wondering if there is some kind of electrical grease that would loosen them up a bit?

Just please keep in mind that reducing the connectors to bullets removes the polarity protection.

I'm disappointed with the EC3 and EC5 connectors. Even with same brand connectors, putting them together completely is really hard and getting them apart is even worse. The housings also started to deform after only a couple of mate/de-mate cycles. I've changed them out with something else.

Cracking fingertips

I have had this problem for a few years--recently started using "working hands" at night and before work--problem solved!

I do a great decending funnel!

+1 on halving EC5s

Been cutting them in half for years. Best of both worlds, polarity protection and easy to separate. Oh, and i don't advise straight bullet connectors for their lack of shielding... you'll discover all sorts of grounding paths you didn't know existed on your model as you fish batteries in and out of the mechanics. Don't ask me how i know this...

Try pulling xt60 apart, then you will love your ec5

Grease them.
It's what I do.

Another way is to buy better EC5 connectors.
The Horizon Hobbies ones are the best.

I literally never use the word literally right.

Guys thank you all for the excellent ideas and suggestions. I am using some hand stuff for my fingers, Neutrogena which helps. Yes I do get dry hands, especially in winter.

I like the cutting the connectors in half idea - I guess I've gotten so used to plugging both neg/pos in at the same time, it's just convenient. Do you have a picture of this?

Vaseline helps really?

Yeah, I guess I was flying too much...

HA! I have some nitros and will never give them up! Gaui NX4, Raptor Titan 50. As most of you, I really like the ease and no-oily-mess of the electrics, but like the just grab-and-go of fuel without having to worry about charging. Best of both worlds.
