About rx200

[Colourless]

I'm currently in the process of moving out of my sister-in-law's house, the lady friend and I just moved to Kentucky and we're in between jobs for the moment. I ordered the mod and batteries right before my last temporary job ended and no one was having issues with the USB charging since it was just released, and I assumed it would be fine.

Do you have "unbalance charging" signal when plugged?

As I said in an earlier post, I just received my RX200 yesterday. Some observations:

I am using Sony VTC4's. I purchased three brand new ones for this mod that are dedicated to it. My new charger did not come yet, so I decided to give the USB charging a try. I carefully measured the batteries several times during the charge by four methods, and compared the three: 1 the internal voltage readings in the RX200 2. My DROK Volt/ohm multimeter 3. My Fluke multimeter and 4. An LED panel mount voltmeter I intend to use as a small portable volt meter. The readings were almost exact on all four meters, and the three batteries were amazingly close (within .01 volt). I also measured the resistance of several different addys, both Kanthal and Ni, and the measurements of the RX200 were dead on. The batteries were at about 50% when I received them at 10 am yesterday morning. It took from 10 am until 3 am this morning to charge the batteries via the USB charging port. Pretty slow, but no heat issues, all three batteries charged evenly, and the vape this morning has been wonderful. My RX200 came loaded with software version 1.07, but I was surprised to see that version 1.08 had been released on Dec. 24, so I did upgrade to 1.08 before I did anything else. Evidently, 1.08 was simply an upgrade in the font, and I found the font on the screen very clear, very easy to read, and very nice. I had zero charging or heat issues whatsoever.

Conclusions: My intention has always been to use my new Nitecore 4 bay charger for the charging of these batteries for the RX200. I even purchased a car adapter for the charger. However, in a pinch, let's say to top off the batteries when I'm out of the house, I would have no problem in using my USB port in my car to the USB charging port on the RX200. I am impressed. This is a great piece of gear. I am spending the day experimenting with different addys, different coils and builds, and the multitudes of settings available to me. I am a very happy vaper today.

and one of the reviewers done a lot of testing and is not that sure that the RX200 is realy capable of good balance charging and recomends if you use one , you should charge the batts externaly . at least as a safety aspect to keep the batts in sync

I bought a separate charger because

I mean if the Manufacturer says it's better...also wouldn't fault them, I mean they told me so.

So i got my wismec rx200 and paired it with 3 brand new lg choc batts.
When i put the batteries in the mod started to heat up, after awhile it stopped.
It also shows that batteries is low.
When i charge the mod(though usb port) it heats up so bad that it burnt my hands.

... man.

Seems like chocolate batteries would melt pretty easily, yep. I like my RX200, so funny though that I got purple efests for it (to keep in line with being a cheapskate, ya know?) and they have this extra layer of clear plastic on the wrappers, so the door won't sit down flush on my mod lol. But it's still holding fast with the four magnets Don't really like these efests...they work but the insulator + saran wrap or whatever you would call it is so fragile, I'll have to replace them due to damaged insulation way before battery life depletion

There are going to be defective units but all four of my rx200's have worked flawlessly since I got them always had married lg chocs battery's and the mods reading of the battery's is a bit off but they are always close when put in the charger. I view the USB as an emergency way to charge rather then the normal way and given wismec say themselves to use an external charger I think it's wise to follow the recommendation.

It should be noted that charging and balance charging are two COMPLETELY different things.

A triple 18650 mod in series requires balance charging, that's where the mod looks at the voltage of all 3 cells and adjusts accordingly so they all end up charging up at nearly identical voltages. Simply supporting charging means they ran 2 cables from the USB to the chip. It would not be advisable to charge this mod via USB unless you know it supports proper balance charging, from everything I've seen and heard I'm almost 100% positive it doesn't, unlike the DNA 200 version. If anyone has a schematic of the internals or a good picture of the chip I'd be curious to find out.
