Best charger that can charge over 1 amp other than Opus and Miboxer?

What was the cell’s voltage when it happened? Once the cell is close to full, the charger will automatically reduce current - standard CC/CV algorithm thing.

3.6V.

Pete I’ve had 2 cells in there charging for 51 minutes now and it says 4.2V but the charger also says the cell is 28% charged.

Can’t beat the Rocket! Press of a button shifts between 1amp to 2 amps and it is relatively inexpensive.

Nitecore has some that do 3A charging IIRC.

That’s a bit much for me. Right now at least. I dont need a charger with bluetooth and an app.

I will look at some of the mentioned chargers.

Is that the Nitecore VS4 or whatever it’s called? New charger (I just seen it) looks like D4 just bigger, tells you if the battery is “good” and such?

Pete I guess I shouldn’t say it’s “too expensive” since I did buy the Maha Powerex for NiMH over $100 lol.

Try some alcohol on the contacts . Should drop the ohms .

Hey pennzy I actually just did clean them last night with some rubbing alcohol. Worked good at dropping the ohms. Seems to be either the protected batteries with issues or the charger. Idk anymore. The percentage did just change from 28% to 81% just now so idk what’s up with that.
That Xtar Rocket looks really nice. Might buy one just because I like the idea of a smaller 2 bay charger like for traveling or whatever. Looks like a nice little charger.

But yeah I don’t get what’s going on with whatever is causing this problem.

Could I just be the batteries?

Oh btw I cleaned the charger with alcohol last night. Used a pencil eraser on the battery contacts today.

Unless it’s preventing you from selecting higher charge currents, I would not be concerned with what it reads. I have exactly one cell that reads low. All others read high . The 26650 is the one that reads low . I think it is also the longest, putting the most pressure on the contacts. With this theory , resistance should decrease by pressing on the slide with my finger but no, it doesn’t so I don’t know whats up with it.

Ok. It seems to be working now. Maybe I just put em in and just let it do whatever it wants to do.
Lol. Thanks all for the help.

Such a drama queen. :slight_smile:

Only me Pete! Only me haha :smiley:

SC4 I think.
Check the specs, I’m sure it has protection against faulty batteries like all good quality chargers do.

Thanks Enderman. I’ll check it out. I said other than Opus because I just bought the BT-C3100 from liionwholesale. I’ve heard (on YouTube) that it’s awesome but sucks pretty much. So I just want a decent charger without breaking the bank. Nitecore chargers are usually priced fairly I think. I’ve only had their old I4 and a few D4 that I gave away as gifts.

Why do you think the Opus one sucks?

I don’t. I just see lots of U tubers commenting that it melted and arguing about stupid stuff. I bought it because I was told and read it is a great charger. If I thought it sucked I wouldn’t have bought it lol.
I don’t mind that little fan noise. Dunno what it sounds like, but if it works then that’s good with me.

Will also suggest the Miboxer C4-12 (charge current is selectable, and it shows IR relatively reliably — for checking conditions of various cells).

The SkyRC MC3000 is probably the top-of-the-line and it’s about twice or more as expensive as the C4-12, but MC3000 seems to be the best (or most functionality that the common people probably won’t get to use).

Both of the above can charge 4x 26650 at 3A at the same time. (both come with a beefy 60 watts power supply brick)

How about an ISDT-C4? You should be able to get one for under $60. It is good for charging pairs of 18650s quickly. You can set the current anywhere between 0.1A and 3Amps per slot. Total charge power is limited to 25Watts combined.

The C4 does not have sliders. Cells that stray too far from the standard won’t work. It is limited to two 18650s or a single 26650. Short cells would need a DIY spacer. It can also charge 4xAA or 2xAAA but not at the same time.

For me, the biggest drawback is the single 26650 slot.

HKJ tested it but not with the latest firmware. The current firmware fixes some of the issues he reported.

Ok everyone it’s the drama queen again lol.

Really like my Opus BT-C3100 V 2.2
But dug my C4-12 back out (i also bought the SV2 Rocket which is awesome)

I was emailing back and forth with Thrunite customer service who were VERY helpful and quick to get back to me about cleaning the cells.

Guess i used the wrong alcohol. So i went and got me some of that isopropyl alcohol (not sure on that spelling) the 91% stuff from Walmart.

Cleaned all my batteries. I haven’t checked this thread in forever but i got some brand new protected panasonic NCR18650B and the IR is crazy again.

Should i try cleaning the contact points on the C4-12 with alcohol and not the pencil eraser which i think i said i did?

I contacted Miboxer on here PM and they said to make sure the charger is completely dry before i go to charge again. So my stupid question is…… how long should i wait for the charger to dry to make sure it’s completely dry?
Never cleaned a charger or any electronic device with any type of liquid form before.

Thanks anyone.

I think this is the thread when JasonWW solder blobbed my Samsung 30Qs. Not sure. I just didn’t want to start another thread about the same thing pretty much
