USB 3.0 increased the number of wires, not the number of connectors, to make it bi-directional. The plug itself is exactly the same.

That's flat out untrue. They have exactly the same number of pins in the exact same configuration. Buying a USB 3.0 cable is actually a scam because there's really no such thing. Where there was a difference was when we went from USB 1.0 to 2.0. They upped the wire gauge to handle the power.

This is getting off topic but 3.0 connectors do have more pins (although they are in the same configuration for backwards compatibility). Usb 3.0 transfers data up to 10 times faster and charges at 900ma instead of 500ma (but you're right that there was a bigger difference between 1.0 and 2.0).

I'd rather discuss why the VS data cable balances during the whole charge rather than just the last 5% like all of my 24g charge-only cables.

USB 3.0 has a wider connector that wont fit the dna 200 port and I wouldn't recommend using 24g charge only cables. I thought the gold-plated cable I bought from Best Buy was charging properly even though it wouldn't connect to escribe. It would stay at 1.95a all the way to 95% before it started balancing at around .5a, but after a few weeks it was going to 0.00a around 94-98% and I noticed it was charging much hotter than the VS data cable (which constantly fluctuates between 0-2a up to 100% every time).

When it stopped charging at 84% last week I connected it straight to escribe and all three cells were at 4.2v but the charge estimate in device monitor was at 8.45wh... I tried setting the battery capacity to 8.45 and the device screen jumped to 100%. I was hoping that was too low though so set it back to 10.22 and changed the DM charge estimate to 10.22 manually and it jumped back to 100% and fully charged on the next cycle. It stopped at 98% the next day though so I figured maybe my battery really was 8.45wh, but tried the VS cable and its been charging to 100% at 10.22wh without getting hot since then. I don't think 24g cables allow the balancing to function properly at 2a because all the ones I own charge at a constant current (all varying widely between 1.6-1-9) while the VS cable is always balancing.

The usb cable has nothing to do with balancing. It just provides 2a/5v power to the board which handles balancing.

I'm not sure what usb cables you're buying but they should have the exact same connector as a 2.0 cable. Micro usb is a specification for the connector. It shouldn't vary at all.

This is getting off topic but 3.0 connectors do have more pins (although they are in the same configuration for backwards compatibility). Usb 3.0 transfers data up to 10 times faster and charges at 900ma instead of 500ma (but you're right that there was a bigger difference between 1.0 and 2.0).

USB 3.0 can support 2.0 or 3.0 connectors. The 3.0 connector is for external devices that require more power than the 2.0 connector is rated for.

They changed the power specs for USB 2.0/1.1 to <1.5a a few years ago but not all controllers will go up that high. Some legacy ports only allow 500ma.

For some reason the only cable I can hook up to Escribe is the VS cable

I emailed Vaporshark to see if that sold additional cables and said they may but wouldn't cough up which vendor the cables that the mod comes with came from.

That's what I thought but then why would they charge so significantly different? Maybe balancing is the wrong term, but it seems like the data cable is constantly monitoring cell voltage and temp while the charging cables just pump straight 1.9a current up to 95%

Same here, I'm going to try an Anker cable from Amazon like @KTMRider suggested a page back. I've had good experience with their batteries

Sounds like a bad cable or a malfunctioning chip.

ill get a DNA 200 when Eleaf puts one in a box and sells it for $50

Helpful right there. Thanks for your opinions, but the Eleaf thread is ------> thattaway. Enjoy their top notch, high end, temperature control, they are all the rage right now.

im glad you found it helpful, im glad to make a contribution

I don't think it would be a bad chip since the behavior is consistent for each of the 4 cables I've tested. None of the charging cables fluctuate like the VS data cable does so either my VS cable is bad or the 2a balance charger requires a data cable to monitor the cells properly.

Does your VS cable maintain a constant usb current or do the amps change every few milliseconds? Mine goes from 1.4-1.9 and occasionally drops to 0 for half a second. Plug in a charge-only cable and it stays at 1.93a

 

[KTMRider]

My Anker cables stay up around 1.92a - 1.95a while charging. I'm using a PowerBot PB5000 usb 5 port charger. One of the best 5 port charger that supplies 2a per port up to 4 ports simultaneously (8a total) and just happens to be very inexpensive too.

Does the anker data cable ever drop below 1.9a before 95% or get hot while charging? Would you mind testing the short VS data cable to see if it maintains the same current with that charger?

 

[Wingsfan0310]

The data cable has nothing to do with the balanced charger. It's part of the mod (inside the mod). The only thing the cable does is supply the power to the balanced charging board. If your amps are fluctuating with only that cable, then it sounds like a bad cable too me.

Cheers,
Steve

 

[moneymike]

I didn't think the data cable should make a difference either but then why is it the only one mine will charge to 100% with... Shouldn't the balance charger hit the same % regardless of how many amps the cable supplies? Even if the Wh in escribe isn't accurate for my pack it should still charge to the same % with any cable. Other people on the evolv forum have reported their VS200 stopping before 100% so I'm hesitant to say my VS data cable is bad until someone confirms theirs maintains a constant 1.9-1.95a

 

[Wingsfan0310]

Hi @moneymike,

The only thing I can think of is try cleaning both the connectors of the cable with a qtip and deoxit or rubbing alcohol, if you haven't already. Could just have some dirt that might be causing the current to fluctuate. Good luck!

Cheers,
Steve

 

[moneymike]

According to this post the fluctuating is normal but I'm going to email them about it for a more specific explanation

VaporShark 200 - DNA 200 Early Adopters Forum

I tried charging the device from a computer USB, iPhone wall charger and a iPad wall charger with the same issue. The issue being that the battery and usb voltage's fluctuate and not in small numbers. I called vaporshark this afternoon, they basically told me this is normal and if the battery holds a charge I am in the clear to use the device. Should the voltages be changing as much as they are? My Hana 200 does not do this.

 

[Wingsfan0310]

I have 3 different DNA200 mods (unfortunately not a VS, all mine charge at 1 amp max). I set the charging display to show USB current. Other than at the very end I get slight fluctuations (.95-1.0 amp). I use various wall warts rated from 1-2 amps. I can understand small fluctuations, but bigger ones make me wonder what's causing it. Maybe since the VS uses quick charging, it functions differently. Now I'm curious.

Steve

What DNA 200's do you have?

 

[KTMRider]

The fluctuation is from the variances of the lipo pack. Each one is different so not everyone will get the exact same results. If it's dropping significantly with 3 of 4 cables, I would suspect those 3 cables are not high quality. It doesn't sound right but there are more cheap cables than good out there and it wouldn't be uncommon to have 3 of 4 cables being sub-par. I have dozens of cables and only 4 or 5 were good (tested with cable tester). That's why I bought some Anker cables.

Back on topic: How clicky is your fire button on your VS DNA200? I just noticed mine barely clicks at all. I checked my rDNA40 and DNA40 and those fire buttons has a very noticeable click. Might be why it locks so easily?

 

[moneymike]

If the current isn't supposed to drop and 8.45wh was accurate then something might've damaged my lipo. This all started right after I installed my shark skin and never changed the case heating constant so maybe that allowed the battery to get too hot.

Mine is extremely clicky but there's been 2 times I pressed the button and nothing happened. Never had it lock on its own set to 3 clicks.
