Battery & Charger Question

[nbates50]

Using "Vamped" 18650 batteries rated at 3.7 volts and 2300 mah and "40 Amps". Using a Trustfire TR-001 charger to charge them. This charger has a switch on the side of it for 3.0 or 4.2 volts. Which setting should we be using? 3.0 volts seems a little low and the batteries dont last that long. We tried 4.2 volts but the batteries get pretty hot but the LED's are still red.
My wife uses these batteries with a Kanger Subox Mini. Lately, the ohms setting (0.5 ohms) on the screen flashes and it wont vape. At times. Sometimes it works fine. Really hit or miss.
Best advice with this combination of stuff? Thanks

You want to charge those batteries to 4.2 volts.

The 3 volt setting is for a different type of battery.

If your batteries are getting hot while charging, stop! something is wrong! You may have damaged your batteries.

Someone more knowledgeable than me should be along to give you good advice, but it sounds to me like you may have been damaged the batteries by over-discharging them.


My batts are usually down to about 3.6 volts when I recharge to 4.2

Batteries can get warm while charging but not hot. Also is the charger getting hot or the battery? Some chargers will get pretty warm and its the charging circuit. Those cheap trustfire chargers might be working to hard to charge a high drain battery.

Warm is ok but hot is bad. When I say warm I mean like someones got a fever warm where its just above your skins normal temp.

I don't like the sound of this.

First, if you were only charging your batteries to 3.0 volts, then using them, there's a chance you've drained them so low they're permanently damaged. "Vamped" cells are suspect at best, anyway.

Still, this makes no sense because a Subox wouldn't fire on that low of a charge...or it shouldn't.

I hate to dip my hand into your wallet, but it sounds like it's time for a trustworthy charger - I like Xtar, the Efest Luc series (but never Efest batteries) and Nitecore Digicharger or Intellicharger series, in that order. Also, if those batteries got hot (not like warm on the back of your palm, but actually hot), it's time for them to be replaced with something trustworthy that's manufactured by Samsung, LG, or Sony with a 20 amp continuous discharge or higher.

I have 2 LUC v4 chargers and love them. One of the finest chargers on the market for price and reliability. Im partial to LG batteries these days. HE2, HE4 or my current faves for my RX200 the HG2's.

I like my nitecore with its display that shows info about charging. And I like my yellow LG 18650 batteries.

She also has 2 red batteries, may be no name, dont know, the printing is pretty much rubbed off. They act the same way. They also get pretty warm. Hot? Well, kinda. Not red hot, but what Id call hot. They also act up in the cig. It may be because the thing has always leaked like a sifter. Bought her a new tank of a different style a while back. Works fine, but it leaks as well. Ive seen juice running out around the buttons and everywhere else. That may be causing the problem. Seems stupid to me to design a tank to hold liquid that comes apart at the bottom. Of course its gonna leak.

This sounds dangerous. Please stop everything and figure out how these things work before someone gets hurt.

Ive had them on for a few hours now at 4.2 volts. Warm, but not "hot".
Yes, I think the whole works can be dangerous. And thats what will eventually get vaping outlawed. Too many "God" mods, mechs, ohms, voltages, messing, fooling, making "clouds", etc. for the average person. Really, who wants to be an algebra mathematician just to smoke? I had much rather just light a Camel Silver. No muss, no fuss. I do have a pen type myself, a disposable rig that came with a battery, 2 tanks and USB charge cord. $15. Works first time, every time. Couldnt pay it to leak. Just pick it up and smoke it. I think thats really all the average person is gonna want. My wife is constantly fiddling and fooling with the Kanger Subox Mini. If it were me, Id just throw it in the bushes and be done with it, lol.

People are accountable for their own actions.

Battery safety doesn't care how you feel about it. Batteries can be dangerous if misused.

O.k., one of them has went to a green LED on the 4.2 volt setting. Took it out and checked it, multimeter says its at 4.22 volts. The other one that still has a red LED is at 4.12 volts. They got warm while charging, but not what Id call real hot.
I still think the problem is in the cigarette, not the batteries. I put one of the red batteries in it and the screen lit up and showed the battery as half full and it wouldnt hit. "Spun" the battery just a little bit and it hit fine. Like it just wasnt getting good contact. The battery contacts in the Kanger look fine. The spring loaded part works normally. Didnt use to have any problem with any of this, just the leaking thats always been a problem.
