Got a bunch of LK 26650s that I forgot I even had(!), and just wanted to test the capacity. Found out the hard way that I can only stuff 2 at a time in it, not all 4 at once like I can do in my almighty Miboxer. Then again, the almighty Miboxer only does capacity testing in slot 4, so thatās 1 at a time, vs 2 at a time in the Ope. Oh, wellā¦
So I load āem up, but thereās no contact. Ironically, not at the positive end (flattops), but at the negative end. Had to slightly bend the sliding tabs forward to make contact, and thatās precarious at best.
Is this an outlier, or has anyone else had issues like this?
And damn, that fanās noisy, yet thereās hardly any breeze coming out.
I used to have to bend the negative ends to make contact with my old crappy UltraFire charger. Never had that problem with the ā3100 though.
I made a holder to do 4 āDā cells for my Opus
Check out the Accupower IQ 338XL. Iām currently using that and can charge 4 26650 cells on all 4 ports + analyze them. Charge rate can also be maxed out at 1500ma on all ports.
I just figured that being stretched to the end-of-travel and only gripping near the edge of the cell vs more towards the middle, was bending it outwards. Probably the shrinkwrap was acting juuuuust enough as a spacer to keep the relatively flat pad from making contact. The perfect storm of no-contact. :confounded:
Right now I got āem going, and am taking care to not even breathe on the whole setup.
Fwiw, these are the blue-wrap LKs, not the black ones. Both tested to 3.6V almost exactly, within a few mV of each other. Both topped off at about the exact same time, and are running neckānāneck in the discharge cycle right now. Nicely matched.
Well, at least this one pair. Still got the other to do.
Fully intend to pull āem when charging back up to about 3.6V as well, vs topping off. Probably going back into storage unless I put a couple more F13s into rotationā¦
Another charger?!? Good God, Iām already hip-deep in chargers. I have a bevy of small LKs plotting to kill me in my sleepā¦
Kidding aside (well, maybe. still not sure about those LKsā¦), looks like a nice charger, but right now my 26es are more of a āspecialtyā item, and canāt really justify getting another charger for something Iād do maybe once per year, if that.
Was just curious if anyone had glitches using 26es in any chargers, specifically the Ope.
Kinda odd that the Ope can only handle 2 at a time, though. Just a hairās more width and Iād be able to stuff 4 in there.
I got a few INR26650-50A (looks similar to Liitokala INR26650-50A cyan, but not labeled Liitokala, because at the time I couldnāt find a seller that ships the Liitokala INR26650-50A to my country, so I just got the plain INR26650-50A from another seller, and they look similar based on the pics). Anyway, I notice that these INR26650-50A cyan, also are extremely picky with my different chargers
I either have to insert or adjust them to a slight angle for the charger to recognize the battery, and the slightest nudge can sometimes knock them out of charging too. Not sure if thereās a better solution for these āvery flat topā 26650s with chargers.
