I've tried a protected UltraFire Li-Ion 18650, doesn't fit. I bought IMR 18650, LiMn 2000mAh Battery, fit perfectly.

I've found this to be the best battery to use in my gripper

My gripper just came in, I can't get it to work. I put in a fresh 18650 and the OLED flashes 3 times and then the device remains unresponsive. Any help would be appreciated.
Remember that shut off when you put in a bag, because the voltage changes pretty easily and 6v with pwm isn't pretty when you aren't expecting it.
im playing around with my gripper and I really like it. I am finding one thing annoying...my cartomizer feels so loose when it is screwed in. The connector in my old lava tubes felt solid (uintil they just snapped off whenI inevitably put it in my pocket with the carto still attached). This connector is loose, not crazy loose, but enough to be noticeable.
I am th inking of a little dab of epoxy under the connector between the plastic. There are a couple mm separation there that could work, but epoxy tends to be viscous and I doubt I could do it without making a mess. Any ideas?

I don't have a gripper and have no clue as to what that looks like inside. But some people use JB Weld to hold things when they do some kinds of modding. Would that work in your case ???
Just a suggestion I'm no stranger to JB weld...both of my older lava tubes looked like some sort of home made pipe bombs near the eds of their lives. I want to keep this box looking nice though.
If you dont want to crack open your case, which isnt hard, you could try winding some wire around the connector under the lip, that might remove the slack.
Went thru same problem with Gripper bought from another vendor, theres a fault in the design as the way the 510 connector sits inside the box.
Fixed mine a good while back by gently prting on the sides and getting it to open , seems like its crazy glued shut thats all.
Once inside mix your JB weld and with a toothpick let it drain off into the slots and around the connector and let it fully cure .
Once fixed no more problems, course they could have used a better quality 510 connector as well but we do what needs to be done which really should not have came out from the factory this way.
Its a design flaw.

Here is what i mean look at the 510 connector its simply resting "kinda" snug but thats all .
As a note this was a picture posted on a gripper in another thread on Ecf as there have been others mentioning this also.
The oled screen is nice and that chipset works excellent i like to add.

The button on these are the weak point, besides the battery door. Have now had two buttons get to the point where they wont fire consistantly. I may need to learn how to solder and order a new button.
You can get a brand called Tool Shop Soldering gun with the silver solder in package for under 5.00 @Menards and or probably Walm.
Button no problems as of yet, the batt door if pried to far or dropped will definitely brake are held on by a plastic pin on each end .
One problem i had was the metal ground that small hole on each end held by melted plastic stubs and easily pops out .
Good ole JB weld again which also fixed a crack in my oil pan on jeep some years back and still holding !
JB weld has made my e cig habit much cheaper. If I had to buy a new mod every time I ended up fixing one with JB I would probably end up spending close to what I save on analog tobacco. In fact I am currently out of quick cure JB, gotta make a hardware store run.
