X5C battery connector
Battery connector very hard to use.

Just got my X5C a couple of days ago.Managed to get a few preliminary trials before one of the motors just up and quit. After a lot of fooling around, I finally took the thing apart and as I suspected, one of the wires to that motor was was disconnected from the board. Poor soldering job I guess. Anyway, I fixed it and after reassembly, everything worked fine.However, I find the connector for the battery is very difficult to disconnect. Pretty sure something is going to give there soon, as I need a small pair of needle-nose pliers to pull the battery lead out for recharging.Anybody else having this difficulty? If so, is there a fix for it?

Hi Suncoaster,

Never had your problem having 3 X5C Quads, the motors are like the same on the Blade MQX

I agree the connection to connect the battery to quad a bit of a pain as explained on review- here

So I marked the battery connector to know correct side up- hope helps a bit.

Thanks for your reply. Getting the proper orientation isn't the problem. Even plugged in properly it still results in a struggle to UNPLUG it.

Avoid making a short on the battery terminals with the pliers the strips of metal are rather close.

Thanx Redfive. I closely examined the battery connector and see there is a tiny bump on each side of the slide (battery end). Looks like it's meant to hold the connection firmly (maybe a little TOO firmly?) together. One of my batteries is harder to remove than the others and I'm contemplating razoring the little bumps down on this one. Trick will be not to remove too much eh?

There are no bumps on mine so reducing them may help a lot

Here's what I see when I examine the connector. Hard to see inside the matching connector in the quad, but I'm guessing its pretty much the same. The two "bumps" slide past one another to form a lock that, in my case, was too tight.BattConnector.jpgImage Enlarger

Having studied mine with a magnifying glass I can see a slight bump on one side just like your picture but don't think there is any harm in reducing it.

Thanks for your interest. I shaved it down with a razor knife on that battery and it now slides in and out much easier. Still feel the slight click connecting--feels like a secure join.

This suggests the bumps were well-intentioned but turned out to be an unexpected problem, so they eliminated them in subsequent production.  

This exchange will be helpful to others who might have the same problem.  Because difficulty in connecting and un-connecting these fragile little components always will, in time, be destructive.

I just received two x5c replacement batteries from an Amazon vendor called "Micro Mall."  The battery connectors fit the socket in the heli quite loosely and require manipulation of the wires to maintain contact between connector and the socket terminals.  

"Micro Mall."

It's not the battery body that's too loose.  It's the connecting plug.  It fits too loose in the socket and I must arrange the wires to apply pressure when the door is closed on them to maintain contact.  But a significant bump causes movement and resultant power-out.  

Ironically, the original battery complaint was the little bumps on the edges of the plug.  Those bumps would solve the problem I'm reporting here.  It occurs to me that complaints about those little bumps have prompted the bettery manufacturer to eliminate them

There are a lot of different batteries out there, not all of the same standard.

Which is why I mentioned "Micro Mall" (via Amazon) as the source of the batteries with the defective connectors.  Their delivery is prompt, the price is right, and the batteries do work.  But there is that connector problem.

Follow-up on my last (above) message:  I had to toss those two batteries I got from MicroMall.  Their connecting plugs became less and less capable of maintaining contact with the copter's socket.
